The Speedtech Pro Touring subframe is an affordable bolt-in replacement that is also designed to upgrade from your worn out old factory subframe and take your first generation GM F-Body or X-Body car to a new performance level. Speedtech Performance's Pro Touring subframe offers the benefits of: Rack and pinion rear mount steering, built in Guldstrand Mod (this gives additional negative camber), coil over shock compatible, adjustable transmission crossmember and more. You can reuse all your current aftermarket suspension components such as control arms and sway bar, brakes and wheels. For maximum handling and performance, upgrade to Speedtech's High Clearance tubular control arm set to hold up to a P275 tire on a 10'' wheel. The subframe accepts small and big block Chevy engines using the stock oil pan as well as the popular GM LS series engines using most after market oil pan and motor mount adaptors.
