1990-1996 BMW 3 Series Rally Rear Suspension Kit by Wisefab

The main idea with the Wisefab axle is to have better kinematics for long stroke and soft suspension and therefore more rear grip, especially side grip in the corners on the throttle. Some kinematic differences are less roll center migration, good camber gain at ride height, but smaller at full droop compare to original, different anti-squat curve, less scrub(track change) with vertical movement, good bump steer, etc.


  • 075-T6 billet CNC machined differential cover
  • Subframe, links, and arms are made of high strength steel
  • Motion ratio (shock stroke /wheel stroke) is 0.935 when originally it is 1.1. It would give 17% more wheel travel
  • Half shafts are equal length for ease of replacements
  • Room for bigger CV joints
  • Tested with 260mm stroke shock absorbers, which made 280mm of wheel travel
  • Room left for 2x62mmOD muffler tubes
  • All the components are zinc coated


  • Improved Handling Performance
  • Better ground clearance
  • Multiple Differential Options

Please Note: Depending on the differential in your vehicle, you will need a different kit. Please make sure to select the correct kit before adding it to your cart.
