These E8X & E9X subframe 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, drift, 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 car’s geometry where it should be. Lifetime limit warranty. Replaces 2 x 33316758259 and 2 x 33316758260 Aluminum inner sleeves are easier to install when they’ve spent time in the freezer and have shrunk under cold temperature.
