Though bolt-on suspension systems work great, if you desire total modernization of the ride, handling, steering, and looks of your classic Pontiac, the best place to start is at its foundation--the frame or subframe. Why? Because your frame is the connecting structure for shocks, springs, control arms, wheels, tires, brakes, engine, and body. A solid foundation ensures that today's larger rolling stock, big binders, and sophisticated air-ride and coilover suspension systems work to their full potential.
We'll look at the latest subframes for the '67-'69 and '70-'81 Firebirds and Trans Ams, as well as new full-frame chassis that can replace the unibody on your Firebird or the perimeter frame on your '64-'72 GTO to make it feel like a brand-new sports car.
