Cayn @ CMP Engineering

The most efficient solution is often the most simple.

That's Cayn's moto.

The company began in late 2016 to answer the growing problem of E46 BMW RACP/subframe cracks and failures.

After discovering significant cracks in his low mileage E46 M3, he put his engineering abilities to the test and began developing what is now a comprehensive range of CMP reinforcement products for E46 BMW’s.

Due to the incredible support from the BMW community and our core focus on delivering engineered, comprehensive products, CMP was able to grow organically over the years offering new products for the M3 V8 and other M chassis.
