82-92 Spohn Sub-Frame Connectors – Coupe Cars

When it comes to locking together the chassis on a third generation F-Body, nobody does it better than Spohn Performance! We don’t consider our kit to be just a point to point sub-frame connection, we provide the components necessary to install a full frame to the underside of your uni-body vehicle.

Our “truss-style” framing system is constructed of 1.75″ x .120″ wall tubing for serious, uncompromised rigidity. The frame rail connects to the front lower control arm mounting area and runs the entire length of the rocker panel, it ends at the rear side of the front wheel well. The main shaft is formed to fit the contour of the floor board, providing for weld contact area the entire length of the frame shaft, and no ground clearance loss.

We don’t stop there. Mid-shaft we install a “Y” off frame that connects the main frame shaft to the beefy front sub-frame at the transmission crossmember mounting area. This provides for the ultimate in chassis stiffening by utilizing a triangulated framing design. The frame rails also provide for an excellent jacking point.

Put an end to squeaky dashboards, cracking body panels on t-top cars, and seriously enhance your chassis’ handling and launch performance.

This is a weld in system that ships to you either bare, or with a brilliant and durable powder coated finish. If you’ve been looking for the ultimate sub-frame connection system for your third generation F-Body, you just found it!

These SFCs are designed to be used on a single-cat or dual-cat y-pipe exhaust system. Passenger’s side main shaft necks down in the front to allow proper y-pipe clearance. No exhaust or floor board modifications are necessary to install our SFCs.

Note: Will not fit on convertible cars

Part #503 SFCs will work on single cat and dual cat y-pipe vehicles
