castor angle
by Mike R :
Fast Road Geometry settings:
Front: 1.5° negative camber, 2mm toe-in.
Caster as close to 3’30° as you can get.
Rear: 1.5° negative camber (not adjustable on standard rear beam, but will normally be around this depending on ride height), up to 3mm toe-in (using shims or by slotting the mounting points and tack welding the beam in position after welding – as per the Grp N cars).
Track day Geometry settings (you will need adjustable TCAs and rear beam to achieve these settings):
Front: 3° negative camber*, 2mm toe-in.
Caster as close to 3’30° as you can get.
Rear: 2.45° negative camber, 3mm toe-in.
*Please note when running such aggressive negative camber on a track car that is 4wd, longer drive shafts may be necessary and also ball jointed top mounts are recommended, so as not to put excessive load on the damper
