Turner Motorsport Subframe Bushings for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Your BMWs subframe bushings were designed to mitigate vibration and harshness. When mileage accumulates these bushings dry out, crack, and eventually split. When this happens vibrations and noise increase. Turner Motorsport carries Genuine BMW and high quality aftermarket alternatives that will restore lost handling and comfort.

The rear subframe is the heart of the BMW rear suspension. Not only do all of the suspension arms attach to it, the driveline runs through it via the differential and half-shafts. Therefore, a track-prepped E46 should never see any flex or deflection in any of the subframe mounts. Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.

The rubber stock mounts flex and deflect as various forces are applied throughout the subframe - on and off throttle loading, cornering on flat surfaces, bumpy surfaces, weight transfer, sticky race tires, etc. Too much flex from worn rubber mounts will transfer to flex where the subframe meets the chassis/floor. This is the primary cause for the infamous rear subframe failure. Solid mounts like these have almost zero flex to them so they will not contribute to rear subframe issues. The Turner E46 Reinforcement Kit is still recommended.

These solid subframe mounts were designed for racing use only, where we won several sports car championships in the Grand-Am Cup series. These subframe mounts are over-engineered to be a major improvement over the stock subframe mounts not only for performance but also in strength as well. We use a Delrin casing as the primary bushing in the subframe. CNC machined aluminum sleeves are then pressed into the bushings. The sleeves have larger surface area with integrated washers to provide a more secure fit for holding the subframe in position. One front bushing is slotted to allow for BMW's manufacturing tolerances. Professional and experienced installation is required.

Rear Suspension Mounts With No Flex or Deflection for Improved Handling, Response, and Long Life
Building a track-only or racecar means swapping out the flexible rubber bushings and mounts for non-distorting solid pieces. The stock rubber bushings have serious drawbacks when used hard on the racetrack - they wear out quickly, and the flexible material allows extreme changes in alignment. Switching to solid bushings will eliminate the deflection and flex, keeping the suspension motions in their intended alignment and providing more feedback to the driver. On the E46 M3, solid bushings can help prevent rear subframe failure as the sheetmetal chassis will no longer flex along with the rubber mount. Depending on the bushing's intended purpose, the material we use is either aluminum or Delrin. Delrin is a dense plastic material that has almost zero deflection and long life. It's self-lubricating so it won't ever need grease or lube. All of our bushings are designed by our in-house R&D engineers and tested on our various racing cars, with many used in professional racing series around the world.

If you're building a car for a racing class, the parts and materials you can change to are specified in the rules. Consult your rulebook or tech steward for any clarification. As these bushings have no play or deflection in them, they are not intended for street-focused cars - they do not absorb impacts and vibration like rubber will.

We offer bushings for the following suspension points -
subframe mounts x 4 (aluminum)
inner-upper control arm bushings x 2 (aluminum with bearing)
differential mounts x 3 (1 Delrin, 2 aluminum)
outer upper/lower control arm bushings x 4 (OE-spec replacements) (steel with bearing)
trailing arm bushings (RTABs) x 2 (aluminum with bearing or Delrin)
suggested: front control arm bushings (FCABs) (Delrin)
suggested: rear shock mounts (RSMs) x 2 (aluminum with bearing)

Notes
Note 1: there is also a inner-lower camber arm bushing. We never developed a solid bushing for this point because every racing class allows adjustable camber arms to be used in this location and we offer those with solid inner bushings.
Note 2: some racing classes require a non-bearing bushing for the rear trailing arm bushings. In cases like this, we use a Delrin bushing.
Note 3: the outer upper and lower bushings are already a monoball-style bearing from the factory on all M3 models. They are a great design and last a long time. We offer them here as direct replacements.
