Hmm, when I had Rayspeeds on there was no way I could of had 4mm ride height, even with proper slicks on. Maybe if I used the inner shock mounting holes on the tower and the outer most ones on the suspension arms, but thats not much use.
Will have a try again sometime this week, but I really liked the Alex Racing springs tonight, I have enough of them to go up and down in small steps.
Good to hear you finaly got your stuff
You're going to love it on the track
