BMW Chassis Reinforcement Kits & Parts

M7 Strut Reinforcement Plates 53-510101 are the ultimate solution for MINI owners facing the common issue of strut tower mushrooming caused by heavy impacts from shocks and low aspect ratio tires. Over time, MINI's shock towers can develop a convex shape, disrupting suspension alignment and leading to a noticeable pull to one side. The M7 Strut Reinforcement Plates (SRPs) address this problem by reinforcing the sheet metal and shock top plate, creating a durable surface that resists bending, even during hard impacts.

Designed specifically for the R50 Base Model Cooper, the R52 Convertible, and the R53 Cooper S, these SRPs are an essential upgrade for any MINI enthusiast. Constructed from CNC machined billet aluminum and black anodized for durability, the 1/2" (13mm) thick plates cover the entire surface of the strut tower, distributing loads evenly and providing peace of mind.

Whether you drive your MINI daily or push it to the limits on the track, M7 Strut Reinforcement Plates offer a cost-effective preventative measure against expensive suspension repairs. Easy to install in less than 20 minutes, the SRPs use the stock nuts for mounting and come with instructions that also guide you through fixing existing mushrooming.

If you drive your BMW in a spirited manner, have an extensive list of modifications such as turbo/supercharger or track your BMW, reinforcement of the subframe is a must. E36 BMWs are known for being very capable machines, but they are also known for less than stellar subframe rigidity. With this kit, it will reinforce where the subframe meets the chassis, making for a much stronger and much more rigid frame. You will notice sharper and more precise handling, and you can stop worrying about costly chassis/subframe damage.

Welding is required, professional installation is recommended.

Reinforce the weak points of your E36 BMW's chassis with this Genuine BMW reinforcement kit. These plates and hardware reinforce where the subframe meets the chassis to increase the unibody's rigidity, helping to prevent potential damage.

Two studs, two bolts, and two nuts that secure the subframe are all included.
