Product Details

Made in the USA A BMW’s subframe is the heart of the rear suspension. The differential is part of the subframe, as it is a stress member system. When the subframe moves, so do all of the rear suspension mounting points. Replacing the stock rubber subframe bushings with solid aluminum will limit drivetrain and suspension movement and keep your car’s suspension geometry the way it’s supposed to be. The Delrin diff mount bushing is a near-solid mount that will last longer than the original rubber and does not 'wind up' under load/unload. This transfers more power through the axles to the wheels. The Turner Motorsport E30 solid subframe and differential mount bushing kit is a direct replacement for the stock BMW subframe mounts and differential bushing. We have incorporated ideas from our other race style solid bushings not only make these very light weight but also to be fully serviceable and removable in the case of subframe or diff cover replacement. This kit is a legal upgrade in many racing classes.

We also sell the Solid Differential mount and Subframe Mounts separately, for those that may already have one of the products or if you desire spares for fast installation. A common example is if you have two differentials with covers, and want to make fast gearing changes at the track.
