Solid Aluminum or Delrin Bushings To Reduce Flex For Better Handling
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, 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 (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 bushings are already a monoball-style bearing from the factory. They are a great design and last a long time. The same bushing can be installed in the outer lower point as an upgrade.
