BMW E92 E90 135i 335i Auto Diff Brace
When launching or accelerating hard in a 335i or 135i, these cars have a bad tendency to “axle tramp or wheel hop”, especially if you are at a higher than factory power level.
This is one of the main causes of broken cv shafts, poor launching ability and just downright feels terrible.
Our one piece differential brace bolts between the subframe and diff, eliminating the unwanted differential movement, which is what causes the axle tramping issues.
Our bracket is one piece, made from 6mm thick Gr250 steel, and is powder coated satin black.
We are not just part makers, but actually a genuine workshop that works on our cars, so we designed this brace so that you can get to the oil fill/drain port without removal.
Comes with all the replacement high tensile hardware needed to fit.
This will only fit models with the medium case diff, please check before ordering, the most common variants are listed below.
135i Auto models (not DCT)
335i Auto models (not DCT)
We have since found there are a few variants of E9x subframes, and some where the brace holes do not line up with the holes in the subframe.
This is an easy fix that we have done a few times in our workshop, simply drill another pair of holes and you are good to go.
We have updated our installation instructions to include this step.
