Depending on how much ICE you have there should be minimal if any trimming of the kit required. I've done nothing to my S2 with a 35mm drop and it only catches if I'm braking hard and hit a bump at the same time.

Didn't catch at all even when driving like a mad man at Bedford

CliffS1 who posts on here has a S1 with 17" Voodoo's might be worth dropping him a PM.
