Description
Another E46 part designed from the ground up by SLG that nobody else offers! This is for when you need the next level of protection from subframe and axle failures.
Take advantage of what is a power capable diff (up to ~450hp) and skip upgrading to a costly M3 subframe setup.
The factory E46 differential mounting setup leaves much to be desired:
- Power is unevenly distributed through the subframe to the vehicle floor causing twisting and notorious cracking of E46 subframe mounting points.
- The diff is held with little leverage and twists more than you may think. In high power applications and/or clutch kicks we have seen bent front bushing mounting bolts.
- Excess movement from the diff contributes to blown CV axle joints, which leads to broken axles.
This kit bolts between the diff and the diff cover then attaches to the subframe via two weld-on tabs.
Kit contents:
- Differential plate
- Two Subframe mounting tabs
- Two heavy duty mounting bolts
Laser cut from steel in the USA.
Install Instructions:
- Remove differential from subframe, and cover from diff.
- Install the large plate using differential seal RTV between the diff and plate, then again to plate and diff cover.
- Torque bolts to 30 ft/lbs after RTV has cured for an hour. We recommend using longer bolts to get more thread engagement as well as not strip the case. 30mm bolts with a washer is safe if using the stock cover.
- Install diff back into the subframe.
- Weld on the first mounting tab after loosely securing it to the diff plate while the diff is still bolted to the original rear mount for correct placement.
- Remove the diff and cut off the original rear mount.
- Install the diff using the front mounts and first tab you welded on. Loosely bolt on the second tab and weld on.
- Remove diff and finalize welding.
- Paint, what you like, install diff, and go rip!
