The E82 and E90/E92 subframes have an inherent weakness in the rear subframe - the mounts are too soft for the power and torque these cars are capable of. The subframe is the heart of a BMW's rear suspension. As torque is transmitted through the differential and axles and as the tires grip the road, the subframe mounts are working to keeping everything in line. That's a tough task to hold when torque is increased with bigger boost (335i) or even mild tweaks (M3). While the M3 subframe mounts are a great upgrade for the non-M chassis these factory BMW Motorsport subframe mounts go one step further.

These Motorsport/Group N rear subframe bushings are a direct replacement upgrade over the stock mounts. They are rubber to conform to the rules of the Group N racing class - so they are still acceptable for street use as long as extra ride harshness can be tolerated. The rear subframe has to come down from the car for these mounts to be pressed in. So now is the perfect time to do other work as well - check out our other Motorsport Race bushings or M3 upgrades.

Price is for the set of 4 mounts.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. E30 race engines can be expensive, so protect your investment! AAF's skid plates have proven their durability on the track. Made from precision cut steel plate, welded in house at AAF, and Powder coated for the most robust surface finish. The AAF E30 Skid Plate is a MUST-HAVE for all PRO3 and E30 Race cars. This skid plate does not use steering rack bolts, so the skid plate can be taken on and off without removing critical bolts or changing wheel alignment like other skid plates. Made specifically for an M20, (with a dimpled relief for the oil drain port, and strong gussets on both sides of the oil pan) but can be used on any E30. Includes a nut plate for ease of installation. Comes with all required hardware. Some drilling required.

These are Gargistic's original poly rear subframe bushings and are modified replacements that will not only reduce play in the rear suspension components substantially compared to the old and mushy OEM rubber bushings, but the "raised" design will move the subframe up 12mm to help correct some of the unwanted camber and toe that comes from lowering an E30. This has a similar effect to raising the suspension so the rear geometry resembles that of a stock height E30. The 12mm raised bushing's average geometry correction (camber and toe) is from -5 degrees to -1.5 degrees depending on your suspension setup. These bushings are slightly stiffer than the OEM units which will cause a tiny bit more NVH to be transferred through the chassis, but the benefits greatly outweigh the small sacrifice in comfort. 80A is the softest poly bushing in Garagistic's lineup and are perfect for a street performance E30 that will see the occasional autocross or track day. We highly recommend professional installation as these will require a press to install as well as remove your old bushings NOTE: When installing Garagistic raised subframe bushings, the differential mount will no longer line up with the mounting provision on the chassis, but there are a couple of solutions for this! The first option is to install extended studs and spacers onto the differential. This will effectively space the differential back down 12mm from the raised subframe back into the factory position. This will allow the use of a standard centered differential bushing and maintains the factory driveline geometry. The second option is to simply run an offset differential bushing. This will allow the differential to be mounted to the subframe in the factory orientation and the repositioned hole in the differential bushing to line up with the factory bracket. This will change the driveline geometry in the rear! Garagistic have used both methods with success on street and track applications.
