Corner weights
For maximum performance, your 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
Equalize all tyre pressures to 30 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
Ensure the factory springs have three turns of pre-load (new cars
will have this done at the factory, and the top platform marked
with a ‘3’). See left to set pre-load.
6
Set the ride height at the front by adjusting the push-rods
7
Set the ride height on the rears by adjusting the spring platforms.
8
Set the camber front and rear.
9
Set the toe-in front and rear.
10
Put car on corner-weight scales, and set corner-weights by
adjusting rear spring platforms. It is usually difficult to achieve
identical settings on each corner. Ensure that the sum of the
diagonal weights are as near as possible.
11
Re-check ride height and diffuser height with the bodywork on.
12
Lock spring platforms.
13
Refit Nik-Links, rear anti-roll bars, reset shocks, and set tyre
pressures.
14
You are now ready to "rock & roll".
Ride height with passenger
The ride height may need increasing when carrying a passenger. The
ride height may be increased up to 100mm at the diffuser, by adjusting
the spring platforms. If you intend carrying a passenger for the
majority of the time, the above procedure should be carried out with
him/her also in the car.
Preparing your Radical
Triple Adjustable Intrax Damper (option)
High speed compression (bump) low-speed compression (bump)
and rebound can be adjusted independently, enabling a more refined
set up to be achieved.
1
Red adjuster on canister: High-speed compression, 50 clicks turn
clockwise for more damping.
2
Small 4mm screw: Low speed compression, 18 clicks turn clock
wise for more damping.
3
Black adjuster on spindle eye: Rebound, turn clockwise for
slower rebound (stiffer).
