You're getting a 1/8, good for you. Remeber my car at Bristol? I went there with a set of 1.1 springs and a set of light aluminum clutch shoes. The clutch engaged at about 30% throttle. Big mistake, as that setup worked really well at Leisure Hours where the traction is phenomenal. If I had a set of .9 or even 1.0 springs, and a set of white teflon shoes, I would have had better luck that day.

That clutch you're looking at may be good for you. Give it a shot and let me know how it works out. I've been eyeballing the Werks clutch, but $125+ (for all the available shoes and the clutch itself) is a bit steep for most people.
