'69 Camaro Z28 RM
Upgrades:
Do the RM straight off & change oil. Then ECU & Eng (I only went to stage 2), race filter & intake man, exhaust piping & cat. Then fit LSD & soft race tyres.
Tune:
Ride Height - as low as it goes both F & R.
Rollbar - F 2 & R 5-6 (rear up to you but both help alot with turning)
Camber - F 2.0 & R 0
Toe - F 0.20 & R 0
LSD - IT 20, A 45, B 15
Tran - 300kph
I didn't change any other settings & managed to win the historic car cup (with a little blocking)!
