Building a WRL, AER, NASA, SCCA, Rally America, or track day BMW E46?  Save a ton of time during the build by using our pre cut parts.
 
BMW Chassis Reinforcements - We developed this reinforcement kit based on a local shop needing a kit for a customers M3. 
Rear Differential mounts - Known cracking issue is addressed to reinforce the Differential mount area. Thicker than the M3 kits. Bending and Welding required.
 
These parts have been developed during various project builds at Izzy's. The parts were developed and tweaked for best final fitment on in house projects.
 
Unless noted, parts are shipped flat with pre cut bend lines that are easily formed with a good vise and a 1 lb hammer. Simply prep the weld areas to bare clean metal, hammer form (or use a press brake) and weld up the cut lines once installation is complete.
 
These are NOT bolt on parts. They will require some fabrication skills and tools to install.
 
Some trimming of edges may be necessary due to production line variances or prior chassis damage/repair.
Hardware not included. BMW not included. For off-road use only. Don't feed them after midnight. You'll shoot your eye out.
