Competition Brakes

Bob,
After open tracking my car, I think the first thing I need to do is upgrade to the competition brakes. My manual lists 12.18 or 12.8 diameter calipers. How much difference between these (performance)? Also will I have to go with pin drives? And what wheel sizes? I am running torque thrust D's now.

Thanks,
DC

Dave,

Unfortunately, the Torq-Thrust wheels don't easily accommodate larger brakes. There's not enough caliper clearance. You'll have to change to a different wheel, like PS's.

12.18" rotors are the largest that will fit into 15" wheels, so if you're serious

, 17" wheels are preferable.

Alternately, better pads and calipers are available for the stock GM setup too. I don't have any experience with them, but I see a dual-piston floating caliper advertised in some of the Circle-track catalogs.
