The rear differential bushing tends to fail on the E46. The subframe will fall apart around it, and will most likely need major fabrication work or another rear subframe as a fix. If yours have given up, or you're looking to prevent this issue from happening at the track, this is what you're looking for. It does not require a different subframe, or differential.
What's included?
This kit comes with 4 quarter inch thick 44 000psi steel plates. Two of them bolt on your differential cover, and the two others are meant to be welded on your subframe. We supply all the necessary hardware and graded bolts.
Do I need a solid diff mount kit?
If you're still using the stock motor, chances are you won't ever need this kit. If you're planning on turbo / supercharge / engine swap your E46, this is a must. The rear differential bushing will give up. We made this kit for a competitive drift car with 518 whp, which had previously experienced a rear diff bushing failure.
Why Tech-53?
Compared to other manufacturers, installing our kit does not require the differential cover to be opened, which can potentially create a leak.
My front differential bushings are not replaced, what's my best option?
We suggest you use two Tech-53 front differential bushing when this kit is installed. The E46 solid diff mount is not meant to be used on factory front bushings.
