drove the F6 in the McRae Rallysprint yesterday, I did a bit of testing in the morning (track day session) and ended up with the coilovers set 8/10 front and 7/10 rear. With better tyres I could have gone firmer, but this felt good. It would have been great to feel the difference between stock suspension and the Shockworks kit, but I'm fairly certain trying this with the stock suspension would have been a disaster. I found the oversteer to be very controllable (considering I've never driven RWD on track before), and the handling was predictable and composed for an 1800kg beast with crap tyres (Sport Maxx).
No mods other than the coilovers and a Herrod intake.
