1. GENERAL INFORMATION A1GP POWERED BY FERRARI CHASSIS MANUAL
1.1. GENERAL DISCLAIMER Motor sport is HIGHLY DANGEROUS and consequently this manual sets out guidance to assist with the safe and correct operation, use and maintenance requirements of the chassis of the A1GP car. The nature of motor sport places the chassis under significant stress and pressure which can create abnormal and extreme operating conditions, also accidents can happen. This manual is provided as a guide only, without representation or warranty and is provided to users on the basis that each user accepts all risks associated with driving a motor sport vehicle and taking part in a motor sport event and to the fullest extent permitted by law, shall be solely responsible for all loss or damage occurring to his or her person or property. A1GP suggests that, under normal operating conditions, the structural components of the chassis when new, would not show material failure before the A1GP car has completed in excess of 8000 Km. This mileage guide is provided subject to all necessary maintenance and regular safety checks being undertaken as appropriate and provided the car is not involved in accidents. A1GP is not responsible for incorrect chassis repairs, or for chassis repairs made outside of A1GP’s designated factory, or by suppliers other than those appointed and recommended by A1GP or in centres not authorized by A1GP. The chassis should be tested and inspected for structural failure not less than 12 months after delivery from the A1GP factory and then each subsequent 12 months and/or upon completing more than 8000 Km and after any major accident. The chassis should also be checked if A1GP or A1GP’s appointed suppliers advice as such. All testing and material maintenance requirements of the chassis should be completed by A1GP or A1GP’s appointed suppliers.
1.2. CONTROLLED PARTS Teams are not allowed to use, test or run chassis parts not supplied by A1GP except for the parts related to driver comfort in the cockpit. Main controlled parts are the following ones: • Springs (front: between 1000 and 1800 lb/in, rear: between 800 and 1500 lb/in with displacement spacers). • PENSKE racing shocks, dampers VDP-45 (no packers, bump stops allowed) • Differential ramps: 45°/65°; 30°/60°; only allowed • Front and rear anti roll bar: Ø 6.5mm, Ø 9.0mm, Ø13.5mm and roll free bar; only allowed • Roll free RHC 3rd spring system: rubber donuts and nylon spacer supplied by A1GP: only allowed • AP Carbon / Carbon Clutch (140mm diameter) part number CP7143-CE02-SC • Brembo Carbon discs and carbon brake pads • Brembo Brake master cylinders: Ø16mm, Ø17.4mm, Ø19mm, Ø20.6mm, Ø22.2mm • Seat harness • Steering Pinion gears : 6 teeth 37mm/rev, 7teeth 43.2mm/rev

CASTOR
When the car is flat (front and rear ride height are identical ) and the front upright inclination is 0.00° [APPARENT CASTOR ] the effective castor angle is 6.06° [BUILT-IN CASTOR ]. With different front to rear ride heights, castor angle changes because of the pitch angle of the car. For instance, with 25 mm front and 55mm rear ride heights, measured at wheel axis, (wheelbase is 3100 mm) the pitch angle is 0.55° and castor angles (both apparent and total) are reduced. Pitch angle : [(55-25)/3100] • 57.296 = 0.55° Total Castor angle : 6.06° - 0.55° = 5.51° Apparent Castor angle : 0.00° - 0.55° = -0.55°
There is no Castor Adjustment.

1.8. FRONT SUSPENSION GEOMETRY RESULTS Reference points: Z “0” Bottom of chassis (top of wooden skid) Notations: •
Wheel Def. : Wheel movement
•
Ride Height: The distance from the bottom of the chassis Z “0” line to the ground plane.
•
R.C. Height: The distance from the roll centre to the ground plane.
•
R.C. to 0-L : The distance from the bottom of the chassis Z “0” line to the roll centre, a negative number denotes that the roll centre is above the chassis Z “0” line.
•
R.C. Parity: The percentage of roll centre change in heave relative to the chassis, 100% would mean the roll centre move the same distance as the chassis moves in heave, more than 100% i.e. 120% means the roll centre movement is more then the chassis moves in heave, and less than 100% i.e. 80% means the roll centre movement is less than the chassis moves in heave.
•
Cam. Angle: The camber angle of the wheel.
•
Cam. Change: The camber angle change of the wheel.
•
VSAL Lateral: The virtual swing axle length, lateral.
•
VSAL Long: The virtual swing axle length, longitudinal.
•
Scrub: The change in lateral wheel movement in heave from the centre line of the car.
•
Unit Wheel rate: The Unit wheel rate is defined as the wheel rate for a spring rate of 1. Mathematically it is defined as 1/VR2.
•
Rising Rate: The rising rate is defined firstly as the increase in wheel rate in heave expressed as a percentage.
•
Inst Rising Rate: The instant rising rate is defined as the rate of increase or gradient of the rising rate curve.

1.10. BRAKES ASSEMBLY
CALIPERS TECHNICAL DETAILS
Introduction The aim of this document is to inform the A1GP Teams about the caliper features and its components giving also information about when and how service it. Caliper technical details P6 28/30/36 Aluminium Mono-block. Front left

p/n XA8.35.12
Maximum stack: 78mm
Caliper service The recommended working temperature for the A1GP caliper is < 210°C. Over 210°C the seals fitted into the caliper can be overheated and they will not guarantee the right performances of the caliper (sealing, roll back, fluid absorption,…). In order to keep under control the caliper temperature Brembo suggests to use its thermo-tape:
scale 132°C/210°C
p/n 025168.10
scale 210°C/260°C
p/n 025168.13
If the caliper temperature goes over 210°C the seals have to be opportunely refreshed. After 2000km the caliper has to be serviced changing the following components: 1. pistons 2. seals 3. pad abutments 4. bleed screws
Ti insert The caliper has fitted Ti inserts in order to reduce the heat exchange between the pads and the caliper body/brake fluid. The thickness of the Ti inserts is 4mm. The Ti inserts are just clipped on the pistons. Even when the Ti inserts are fitted on the pistons the maximum carbon stack is 78mm.

CARBON-CARBON BRAKES
Introduction The aim of this document is to help the A1GP Teams on managing the carbon friction material. Because of wear rate and performance are strictly related with the pads and the disc working temperature in the next rows the brake system cooling will be focused. Carbon technical details Disc Carbon material:

Carbon material working temperature In order to have the best performances from the carbon material MBC 100 the disc working temperature at the beginning of the braking phase (it is what Brembo calls “Initial Temperature”, measurable in the end of the straight before touching the brakes) have to be in the range of 350°C-550°C. Use the Brembo paint (p/n 02.5711.10) on the discs in order to check the disc temperature. In a normal use it should be:
the green paint completely turn to white (T> 430°C);
the red paint turn to white just close to the friction surface (T>610°C);
do not remove paint as it erode the surface when removed;
On a green track, during the first practice, Brembo suggests to start always with partially blanked ducts (from 20% to 50% it depends on the circuit duty). After the first run adjust the duct blanking in order to guarantee the correct working temperature of carbon material and caliper.
Bedding With new discs and pads it is necessary generate a high temperature in order to guarantee the quick bedding of the disc and pad contact surfaces. On the out lap the driver has not to be too gentle on the brakes in order to avoid any glazing problem. Brake ducts: about 50% blanked. Page 26 of 99
Glazing The “glazing” is a physical phenomenon that happens when the carbon material is used in low temperature/energy conditions. If the disc and the pads are glazed the friction coefficient drop dramatically creating problem on the brake balance and on the braking performance. It is quite easy recognize a disc or a pad glazed: the surface looks shiny and touching it with a finger it remains normally quite clean (or cleaner than with the carbon not glazed!). On the A1GP car the rear axle is more sensible to the glazing because of the balance distribution and the brake system cooling, this is the reason why Brembo suggests to the teams to consider always a partial rear duct blanking on the light duty tracks. The glazing is a degenerative phenomenon, if it starts it is possible trying to recover blanking the ducts and asking the driver to push hard on the brakes. In this case the best thing to do is glass paper the disc and/or the pads in order to remove the glazed layer. In case of rain / cold conditions / extremely light track Carbon can be used in raining condition without any problem, but a blank of the air ducts of about 50% is recommended in order to have the initial disc temperature higher then 300-350°C. The same procedure has to be followed if the track is extremely light on brakes or if it is in low grip condition. New pads on a used disc It could happen it is necessary fit new pads on a used disc or vice versa, in these cases for the first laps the pedal could feel a bit longer because of the pad and the discs surfaces have to be bedded. In this case Brembo suggest to follow the same procedure recommended for the “bedding”. Remember that disc and pads must be changed when the minimum thicknesses are: DISCS
PADS
New
Minimum thickness
New
Minimum thickness
28mm
17mm
25mm
12mm
The Minimum thickness is based on piston travel and covers the situation where 2 pads are at 12mm and disc at 17mm, then the caliper pistons are still within the caliper seals. If the pads are thicker, the disc could be thinner.
Disc resurfacing The discs can be resurfaced in order to have flat rubbing surfaces and the disc holes centred in the disc thickness (the disc wear could not be even between the two half of the disc). The disc resurface is not easy and if it is not done properly the disc could generate judder. If you are going to resurface the discs Brembo recommends to contact Brembo and send the discs to the Brembo factory in order to be machined.
Page 27 of 99
Storing Carbon discs and pads must be stored in appropriate boxes in order to avoid any possible damage during transportation.
Contamination Carbon discs and pads do not have to go in touch with lubricants, brake fluids, hydrocarbons, solvents or acids.
Notes The thickness of the discs and pads to start a Race is a different situation; the wear prediction has to be calculated from the practice sessions. Brake balance: 56% starting setting

1.16. FUEL SYSTEM The Fuel system layout is as foollows:
Fuel tank gasket assembly: Fuel tank gaskets are assembled using Hylomar. Procedure: • • • • • •
Check carbon sealing surfaces for burrs, flatness and cleanliness. Dilute Hylomar in Acetone to a brush on consistency. Brush Hylomar on gaskets and all sealing surfaces on fuel tank and carbon parts. Assemble parts using correct length bolts and torque to: M5 2.5Nm, M6 3.5Nm Re-torque after one hour. Leave up to four hours before fuelling
Opening up the fuel cell in the field: It may not be possible to follow this procedure in full because of time restraints, new gaskets most always be used and sealed with Hylomar.

Page 48 of 99
Filling and Bleeding. The cooling system is filled though the neck of the pressure cap on the header tank. The system uses deionised water with water wetter additive, Shell Q Quench at ratio of .04litre to 1litre of water. With the Kenlowe water heaters connected and running bleed the system using the bleed nipple on the side of the header tank. When the system is bled start the engine, run the engine until the water temperature reaches 80°c. At this point remove water from the header tank by opening the bleed nipple to achieve the correct water volume of 475cc (see drawing). Fit pressure cap and pressurize the system to 1bar gauge using the Schrader valve mounted in the header tank. Ones this procedure has been completed it should not be necessary to be repeat unless the system is opened, or for some reason the system does not reach 1bar at 80° when the engine is re-started.
Preheater Scheme. The Preheater scheme when connected as follows:

1.22. BATTERY The battery used is a RTR15 12v 15amp The characteristics are as follows: CHARGING PROCEDURE Only use specific DRY BATTERY chargers!!!! • The charger must give a constant tension of 14.27V • The charger must be able to charge with a current of at least 40% of the nominal capacity of 12Ah, which is about 4A. The current will come down during charging. • A complete charge can take up to 10 hours. SAFETY NOTES • Never charge the battery when the battery is “HOT”. • Charge an empty battery immediately, do not leave it empty. • When the battery is stored do not let the tension come down under 12V but charge it again as soon as possible. • Store the batteries in an ambient temperature of about 25°C. Hotter conditions will reduce the life of the battery. • Make sure that all breather holes stay un-covered. • Fit the battery securely in its position, without fitting it too rigidly. Use some extra foam to reduce vibrations. DOWNLOAD PROCEDURE • Always connect the car to download battery which has a charger built in.

The Third Spring is used to control the dynamic ride height in heave and braking. Depending on the number of Donuts used, different curves ca be achieved. When one rubber donut is taken out it is replaced by a nylon spacer. Note: Donuts must be assembled with a coating of silicon grease. The Gap where the 3rd Spring makes contact can be adjusted with the Adjuster. Both Front and Rear systems work in the same way. The engagement gap is referenced at static ride height in the VDP program.

2.4. RIDE HEIGHT CHECK AND REFERENCES Ride heights are critical for setting and changing the aerodynamic performance of the car. It could be difficult to measure the ride heights directly, so we provide alternative references. The example shown is the car in the design configuration with front ride height 25mm and rear ride height 55mm (at the wheel axis under the skid). Pitch angle in the design configuration is 0.554°. (3100 wheelbase)
Measuring front ride height: [ 1 ] There are two flat areas provided on the top of the Monocoque aligned with the front wheel centre line, at 576mm from the bottom of the car, (under side of skid (plank), 10mm below the “0” line). Their distance from the ground is 601 – 576 = 25mm. [ 2 ] A flat surface is about 216.4 mm behind the front wheel centre line (front of the skid). You can calculate the ride height at the wheel as follows: measured 27.1 – 216.4 * tan (pitch angle) = 25mm Measuring rear ride height: [ 1 ] There is a machined area provided on the gearbox, aligned with the rear wheel centre line, at 409mm from car bottom, (under side of skid, (plank) 10mm below the “0” line). Its distance from the ground is 464 – 509 = 55mm. [ 2 ] Under the flat bottom, about 200mm ahead of the rear wheel axis, there is a flat surface (Rear of the Skid Plate). You can measure the ground clearance and calculate the ride height at the rear centre line as follows: measured 53.1mm + 200 * tan ( pitch angle ) = 55 mm For a more general procedure: • Define your desired ride heights, front and rear ( F & R ) [mm] • Calculate the pitch angle 57.29 * ( R – F ) / 3100. • Calculate which value you should measure from the reference you choose.

3.1. FRONT WING ASSEMBLY The different Parts of the Front Wing Assembly are:
3.1.1.
FRONT WING MAIN PLANE
The Front Wing Mainplane height on its bottom surface lowest point is:
To set these values, different Shims with thickness of 0.5, 1 and 2 mm are provided (nominal distance is 2mm) for assembling it to the pylons:
Page 82 of 99
The angle of the Mainplane is fixed to 1.5 degs referenced to the 0 line.
3.1.2.
FRONT WING FLAP
Flap angles can be adjusted with the Flap adjuster. One complete turn of the adjuster is one degree in Flap angle.
The angle range of the Flap is from 15 degs to 27 degs.
A gurney can be fitted on the gurney to obtain an extra front downforce and balance, the gurney is attached by means of double sided tape: Page 83 of 99
3.1.3.
FRONT WING END PLATE
The End Plates are assembled to the Mainplane and is where the flap adjusters are located. Rub Strips are fitted on the End Plates in the designed position, with no adjustment:
Dimensions referenced to the 0 line are the following:

Page 88 of 99
3.5.3.
REAR WING MAIN-PLANE ADJUSTMENT RANGE
The Adjustment of the main-plane assembly is made using the five holes located in the End Plates: -
The adjustment goes from the lower incidence in P1 (top hole) to High incidence in P5 (lower hole).
-
Low Downforce configuration is based in the range from P1 to P3 without gurney.
-
High Downforce configuration is based in the range from P3 to P5 with the 10mm gurney.
-
An Extra Downforce position can be achieved with the 20mm gurney in P5.

3.6. AERODYNAMIC DATA This data is to be used in conjunction with the VDP (Vehicle Dynamics Program) to aid set-up of the A1GP-F01 car. The information given in this report has been taken from data recorded from accurate modelling of a 40% scale model in a closed section constant Reynolds number wind tunnel at Southampton University. Track testing of the A1GP-F01 car has given a close track to wind tunnel correlation of aerodynamic forces and radiator cooling information. Notations • • • • • •
All forces are quoted in Kilograms (Kg) @ 240kph assuming ISA conditions. All dimensions are full scale in mm. Ride heights are quoted in mm from the ground to 10mm below and perpendicular to the reference plane (“0” line) the under side of the plank at the front and rear axle centrelines. Radiator data is given as a delta percentage of velocity from the base line configuration. All front wing angles are quoted in degrees. All rear wing angles are quoted in hole positions.
Aero values are given @ the following ambient conditions; Temperature = 15°C Pressure = 1013 mb Humidity = 0% (dry air) Aerodynamic forces are function of air temperature, pressure and humidity because they affect the air density. Typically, Higher Air Temperature by 10° F ( 5.5 °C) reduces downforce and drag by 3.0 % Higher Air Pressure by 1” Hg increases downforce and drag by 3.0% Higher Air Relative Humidity by 50% increases downforce and drag by 0.5% Drag: Downforce: Front Downforce: Rear Downforce: Front Balance %: Efficiency:
Total drag of the car including the contribution of front and rear wheel with Tyre profiles. Total downforce generated by the car, excluding wheels. Downforce acting on the front tyre contact point. Downforce acting on the rear tyre contact point. Downforce percentage spilt on front tyre contact point (=100*Lf /Lt) Total Downforce divided by the total Drag L/D
