Ride Height
The ride height may need increasing when carrying a passenger. The ride height may be increased to
100mm at the splitter, by adjusting the spring platforms. A “high ride height” front splitter and side
skirt will be required to achieve the 100mm maximum ride height.”
Brake Bias Settings
Set central to two turns towards front (clockwise on the dash adjuster). Further adjustment can be
made to suit individual circuits and tyre configurations. Adjust bias to the rear in wet conditions.
Corner weights
For maximum performance, the Radical should have the corner weights accurately set with the driver in
situ. The procedure is as follows:-
1.
Position the car on a flat, horizontal surface.
2.
Equalise all tyre pressures to hot setting, say 20 psi.
3.
Take all readings with driver in car, or equivalent weight in the seat.
4.
Remove bolt from one end of the front and rear Nik-Link, and adjust shocks to full soft.
5.
Set ride height front & rear, then camber front & rear and finally toe-in front & rear.
6.
Put car on weight scales, and set corner weights by adjusting spring platforms
*
. It is usually
difficult to achieve identical settings on each corner to within 10%. Ensure that the sum of the
diagonal weights are as near as possible.
*
When using pre-load, adjustable push rods are used to set ride height and corner weights
7.
Re-check ride height and splitter height with the body on.
8.
Lock spring platforms.
9.
Refit Nik-Links, rear anti-roll bars, reset shocks, remove driver or similar weight, and reduce tyre
pressures.
10.
You are now ready to “rock & roll”.
Note: If you intend carrying a passenger for the majority of the time, the above procedure should
be carried out with him/her in the car.
General Car Preparation
To keep your Radical looking at its best the fibreglass and carbon fibre items can be quickly and
effectively cleaned with polish, while all chassis, suspension and panel parts can be kept looking new
and corrosion-free by wiping them down with a cloth sprayed with WD40.
