Tech-53 rear sub-frame bushing kits have been tested on track for a few years already; our rear subframe bushing kit, is made to tight tolerances, and top-quality materials. These E46 bushings are made of Delrin and go through very tight quality control. This enables you to have no slop after install. Our internal sleeves are made of strong and lightweight 6061-T6 aircraft grade aluminum.

These bushings are made for the track, drifting, and hardcore driving, giving instant feedback of the rear end of the car to the chassis. The Delrin material is resilient, but not enough to produce flex, and keeps your cars geometry where it should be.

Lifetime limit warranty.
