Spohn Performance's tubular k-member sets a new, higher standard of performance and quality. When we designed our k-member, we had several goals in mind. One was to provide the performance capabilities needed for the toughest race tracks, another was to provide the strength and durability required for the demands of a daily driven vehicle. Our k-member provides substantial weight savings and frees up a lot of room in the engine bay for our drag race customers, but it also provides the strength, rigidity, and durability for our road race, autox, and daily driver customers as well..... all in one package!

Spohn's tubular k-member features boxed a-arm mounts for maximum rigidity and side load support. Our k-members are gusseted in critical areas to ensure that a weld never breaks. They decrease overall weight, and provide much more room for large tube headers, turbo systems, etc.

Our k-member will accept stock a-arms, or for additional weight loss and performance enhancement tubular a-arms can be added. K-members are available set up for stock style coil springs or in a coil over version that eliminates the upper spring perch for additional weight savings. Our jig was built around the factory k-member providing for an exact fit and factory exact dimensions. Every detail of the factory k-member was incorporated, including brake line mounts (there's no "zip tying" of the brake lines with our k-member) and optional front k-member brace mounts.

All 1986-1992 cars were factory equipped with a triangular brace on each side of the front of the k-member to reinforce the front subframe at the steering box mount. These braces reduce flex and cracking of the front subframe and are a recommended addition for any street driven car.
