6. CAR SETUP
When the car leaves the factory, it will have a base setup on the car which is displayed below. This is a
setup which has shown to work, eds as they feel
more comfortable with the car.
6.1 HOW TO SET UP THE CAR
Setting up the Radical may seem a daunting task at first; however, adjustments are incredibly simple with
everything being of easy access allowing for fast setup changes whenever you feel the need to adjust certain
areas. Below is a step by step guide of how to work with the car on the flat patch.
1. Check front pushrod lengths are equal & front springs have the correct turns of pre-load. The front
pushrod is jigged from production at 230mm.
2. Check rear spring platform-to-cap distance is equal (approx. 125mm)
3. Ballast with 80Kg (10Kg in footwell by the pedals, 70Kg in seat) unless specific driver weight is known.
4. Lock steering to straight ahead using dummy steering wheel
5. Set tyre pressure to hot pressure from setup sheet
6. Disconnect front & rear anti-roll bars
7. Check dampers are set to full soft all round, bounce & roll car to settle suspension
8. Check drop heights and adjust average of front & rear to be within 1mm of target
9. Set cambers (+/- 0.1° from target)
10. Set toes (+/- 0.5mm from target)
11. Roll car off platform, turn on scales and zero
12. Roll car back onto platform, repeat bounce & roll
13. Check corner weights. Target is within 5Kg across front, and within 2% for diagonals
14. Adjust to correct using rear platforms only
15. Re-adjust drop heights equally on front pushrods and rear spring platforms to achieve target. (The drop
height will probably not be equal, due to the offset seating position, so target drop height should be an
average of the left & right readings.)
16. Re-connect anti-roll bars making sure there is no pre-load
17. Set dampers, they should always be set from fully closed.
18. Turn off scales
19. Check the diffuser is level side to side and front to back.
6.2 CORNER WEIGHTS
One of the most important factors is to ensure that the front corner
weights are as equal as possible. The cross weight is not as crucial
in comparison. (The offset driving position of the driver will usually
mean that the weight cannot be made exactly equal.)To adjust the
front corner weights, raise or lower the diagonal rear. The maximum
difference in front weights should be no more than 5kg (11
155kg 160kg
223kg 229kg
Cross% =
