Front Subframe Reinforcement Kit - E46 323i/325i/328i/330i/M3
A must for E46 cars used on track - subframe insurance
Our E46 Front Subframe Reinforcement kit is a must-have solution for E46 3-Series that see use on track, or that have upgraded power over stock.
The front subframe is highly stressed during high-performance track driving, and it will crack quickly on a heavily tracked a E46. Cars with upgraded power, even when driven on the street, can also suffer significant stress in this area, so careful inspection is recommended.
Our reinforcement kit consists of two (2) precision-cut plates that should be installed as a preventative measure, but they can be used to repair a damaged subframe in some cases. We recommend installation of this kit prior to finding damage.
Welding required for installation.
