what is a good clutch for racing

A lot of guys use aluminum shoes but I like the Ofna composet shoes and mugen springs.

Obviously the are better for racing when boiled.

I already answered this but the reply confused the American moderator and was deleted. Ho hum, they shine again.

Try a search, there is already a thread on this.

I use nova rc 7075 t-6 aluminum adjustable clutch shoes. Very good shoes. Nova rc.com

I also run the Nova RC adjustables. They work well, much better than I thought they would. They're pretty cheap too, I get 'em on Ebay.

Werks 4 shoe or a Fioroni turbo slider.
