Set initial front droop at 5.5mm. In bumpy or low traction
conditions, lower droop will help to improve traction and
handling. In flat or high traction conditions, higher droop
will increase response and reduce traction roll.
Set initial rear droop at 4.5mm. In bumpy or low traction
conditions, lower droop will help to improve traction
and handling. In flat or high traction conditions, higher
droop will increase response and reduce traction roll.

0.5mm shims are used between the steering block and
C hub. Axle height can be varied by moving these
shims. Generally, higher axle height will increase
steering response - good for smaller/technical layouts.

The default rear toe setup for the R12 is -3.0 degrees. When installing ATS, please setup toe linkage at
15.3mm to achieve -3.0 degrees. The rear toe can be changed by adjusting the rear toe linkage length or
suspension block inserts - with a longer link resulting in less rear toe.
There are 4 locations where shims can be added/removed to setup the amount of toe angle change during
cornering. The default setup is 2mm inside and 0mm outside. The angle of the ATS linkage will affect the
amount of toe angle change - the flatter the linkage angle, the lower the amount of toe angle change.
