too heavy

By Budd from Michigan on 11/20/2010
Pros:
Quality was fine
Cons:
I did not use the brakes
Bottom Line: No, I would not recommend this to a friend

Brakes were too heavy to put on to my race car. I can't send them back as they weigh so much it would cost alot to ship back. So I will try to sell them for less than I paid.
