1969 Ford Mustang Boss 302 Trans-Am Brake Swap - MMF Tech
Upgrading Your Classic Colt With Vintage Trans-Am Hi-Po parts
With the Trans-Am upgrade, the difference in braking was immediately apparent. Stopping distance was dramatically reduced, especially from 120 mph going down the front straight on the Thunderbolt track. However, this article is about results, so while we were at NJMP, track manager and Mustang vintage racing guru, Joe Volpe gave us some time on the front stretch of the Lightning course to do our final stopping test.
With the upgraded Trans-Am-era braking components bolted on, our 60-0 stopping distance average checked in at 130 feet. While 9 feet may not seem like much, it's more than enough room for you to avoid an accident, or brake later into every turn on the road course. Plus, with the larger components, brake fade will be lessened.
Once we finished our brake distance testing with the new brake setup, we installed a set of super trick race-type brake pads from Porterfield for the rest of our open track weekend at NJMP. Once these racing-type pads warm up a bit, they really slow the car down well at racing speeds. Running the Boss around the road course is much more manageable now with reduced brake fade, more overall stability, and increased driver confidence. It's a small price to pay for all the brake dust on the front wheels!
