Putting on: E34 540i Rear Subframe and LSD

7:09 pm in My E34, Post-V12, Suspension, transmission by Tom Goh

The parts are being bolted as i post this. I have been running the E34 with my old E30 3:73 LSD mounted on the older, smaller E34 rear subframe. How, you ask?, well that’s because i’ve also been using the M20 long-shaft and most other rear drive parts, including the driveshafts, brakes. That is unacceptable but good enough until now. So I recently found a guy who supplied me with the 540i rear axle complete with:

  • 540i Subframe
  • 540i 2:93 LSD
  • 540i 15mm rear anti roll bar
  • 540i Driveshafts
  • 540i Longshaft
  • 540i Ventilated rear brakes

Pretty lucky to have found these parts and are still in supreme condition. Possibly parted from a mint 540i

Rear brakes – Ventilated (not illustrated?)

Let’s see how it drives. I have been having vibration problems from the longshaft as well as embarrassing top speeds. Not to mention rear diff free-play from the E30 LSD
