• Sub-Frame Connectors, 82-92 Camaro or Firebird

SFC's for 1982-92 Camaro or Firebird (F-Body) Coupes and Convertibles


These SFC's (Sub-Frame Connectors) are manufactured for us by Alston Racing. They are designed to fit the 1982-92 Camaro or Firebird (F-Body) coupes and 1987-92 Camaro or Firebird (F-Body) convertibles. These SFC's differ from the majority that are on the market in several ways. Most aftermarket SFC's are perimeter-mounted. This means they run along the pinch-rail just behind the side ground effects (if present). That design of SFC will not work for a convertible, since ASC (the company that did the factory authorized convertible conversions) riveted a formed sheet metal reinforcement piece in this location. That design of SFC also fails to tie into the front sub-frame that the engine cradle and transmission are hung from. Some manufacturers attempt to correct for this by providing additional tubing pieces that are to be welded from the SFC to the car's front sub-frame near the transmission cross-member. This does indeed tie in the front sub-frame, but it is a cantilevered point, which will be weaker than tying into the front sub-frame directly. You also have the additional weight of these pieces to contend with.

These SFCs are markedly different in several key areas. They hug the contour of the underside of the car and bolt or weld (your choice) in to the front and rear sub-frames. The front saddle of the SFC exactly fits the transmission sub-frame. The rear saddle of it ties into the rear sub-frame adjacent to where the LCA's (Lower Control Arms) mount. This provides a continuous solid support tying in the front and rear sub-frames of the car. The SFC's also provide a convenient jacking point when you need to lift your car.

The SFC's are Jig fitted & Welded of  1 5/8” diameter round tube with .134 wall. The formed saddles that mount to the car body have 1/8” thick mounting plates. The SFCs are powder-coated gloss black or red (optional). The SFC installation kit includes Gr. 8 bolts and nylon-insert nuts and instructions. The installation kit allows you the option of drilling the car frame and installing them at home and driving your car to a shop to have them welded in place to further tie them into the frame. You could skip the drill and bolt process and just weld them in place instead.
