I have installed the option 6 last week & still running it in, You end up with a reduced peddle travel which is going to take a little to get use to but the clutch it self couldn't be better.Mal's help was 2nd to none, he still thinks the option 6 was over kill for my set up. To keep a clutch for a car that is going to be doing alot of stop starting you best not go away from an organic plate.. Mal's option 3 would suit quiet well up to 400kw. Also there are a few double organics that will suit your needs. Exedy ceremic are crap & I agree there warenty is below par,, mine lasted 2 weeks with 1 burnout then it was gone. It sounds as if they have burned alot of customers..Don't buy 1. Muzza.
