Subframe Bushing Reinforcement Kit

The Revshift Subframe Bushing Reinforcement Combo Kit is engineered for BMW E46 models (323, 325, 328, 330, M3, Z4) to address the notorious issue of rear subframe mounting points cracking and ripping out over time. This comprehensive kit includes precision laser-cut 14-gauge steel reinforcement plates designed to weld onto the chassis, preventing future cracks and damage. It also features Revshift's polyurethane rear subframe bushings, which completely replace the OEM rubber bushings. By stiffening the subframe mounting points, these bushings significantly improve the vehicle's handling capabilities. Customers can choose from three hardness levels for the polyurethane bushings: 80A Street (Black) offers a slightly stiffer and stronger option than OEM rubber with no increase in noise, vibration, or harshness (NVH). The 95A Track (Green) is significantly stiffer and stronger, providing a noticeable increase in NVH, making it ideal for enthusiastically driven street and track cars. For dedicated drift and track cars, the 75D Drift (Teal) option offers drastic stiffness and strength with a moderate increase in NVH. This combo kit includes all necessary reinforcement plates, subframe cross member spacers, trunk patch plates, front and rear side polyurethane subframe bushings, and a packet of Revshift bushing lube. Please note that this kit requires welding, and professional installation is strongly recommended. The product is made in the USA and comes with a lifetime warranty.
