> Why should I buy a full frame for my unibody car as opposed to bolt on suspension or a subframe?
The suspension and engine in unibody cars bolt to sheet metal, which results in significant flex under higher-than-stock horsepower conditions, as well as around corners and over bumps. By adding a full frame, everything (suspension, engine, etc.) fastens to the rigid frame. This frame takes the twisting forces away from the body, resulting in a more comfortable driver experience. Additionally, adding a frame to a unibody structure strengthens the entire package compared to just adding subframe connectors. Our main rails are mandrel-bent which are much stronger than tubing formed by a normal bender.
