I raced my car on Friday night and it performed better than it had ever done before, the difference between fastest and average laps was about 4/10th sec and the car was very easy to drive consistently. I had previously been using a setup more suited I think to a high traction surface, but we run on Prima Felt GT with a low to medium level of traction.

Here's the setup I used.

Front

5deg blocks, 6deg static castor, 1.5 deg negative camber
Silicone lube on kingpins (it dries fully so nothing sticks)
1 deg toe out
Jaco 2x pink, 80% additive, 42 mm dia
4mm ride height, servo up, AE 0.020" springs

Rear

5000wt oil in side dampers, forward position on pod plate
Gold spring, 30wt oil in centre shock, 1mm spacer under forward ball stud (HB Shock)
Thin L plates, stock roll centres on all three balls
Batteries fully back
Jaco Yellow, full width additive, 44.5 mm diameter
4mm ride height, pod level, 1.5 mm droop
