Disc Brake Kit

By RockstaR Motorsports from Myrtle beach, South Carolina on 2/9/2010
Pros:
Lightweight, Simple Install, Very Universal
Best Uses:
9" Ford Rear End
Bottom Line: Yes, I would recommend this to a friend

Have purchased 3 sets of these. 2 for a dirt track car and the third on our drag truck. Great kit and simple. Will buy them many more time I'm sure.
