Race Cars Designed to Win
5. FRONT PRE-LOAD AND RIDE HEIGHT
Set the pushrod and damper length to the standard settings prescribed in the link setting sheet.
To set the car to run zero droop, first ensure springs compress slightly when the driver sits in the car
by winding off any pre-load above zero droop. Then wind the platforms up one 360 degree turn at a
time until the dampers are fully extended. The ride height should now be adjusted via the pushrods.
On smooth fast circuits you can run up to one turn of pre-load above zero droop.
For bumpy circuits run 5mm of droop measured at floor. Set using the same methods as for the rear.
6. REAR DROOP AND RIDE HEIGHT
The rear suspension runs 5mm +/-3mm of droop as standard. Set the pushrods and dampers to the
lengths prescribed in the link setting sheet. Measure height of rear bottom wishbone ear (with driver
on board) and then lift the car with a jack until the dampers are fully extended and re-measure.
The difference in the two measurements gives the droop. Adjust via spring platforms, up giving less
droop, down giving more.
The ride height can now be adjusted via the pushrods.
7. FRONT CAMBER
Measure the cambers with the driver on board and ride heights set. Use a camber gauge vertically
across the tyres and adjust via shims.
Camber is adjusted by lengthening or shortening the front upper wishbone outer joint using the
camber adjuster.
8. REAR CAMBER
As for front, camber is adjusted by lengthening or shortening the rear upper wishbone outer joint using
the camber adjuster.
9. TRACKING
Use parallel bars only for setting the tracking. Align the parallel bars with the centreline of the car and
measure the distances of the front and rear edges of the tyres.
The difference gives the amount of toe-in. Adjust accordingly.
