KYOSTAR Diff Lift Bush Kit & Dual Mount Bracket For BMW M2 F87 F80 M3 F83 M4 BK

 

Description:

  • Upgrade your BMW F-series M2/M3/M4 differential mounting system. The factory diff only has one rear mounting point. Our offset bracket kit adds a second mount and replaces OEM rubber mounts, lifting the differential 10mm to fix driveshaft geometry. It delivers rigid performance while controlling peak forces via special sliding bushings.

Features:

  • Adds a 2nd rear differential mounting point, paired with solid bushings to minimise flex and axle wind-up, delivering more direct power to the wheels and sharper road feedback.
  • Raises the differential by 10mm to correct driveshaft angle, making axles more horizontal. Reduces friction, wear and heat, extending the service life of your driveshafts.
  • Unique sliding bush design: retains rigid-mount performance while absorbing minor chassis deformation, avoiding excessive stress that comes with fully solid fixed mounts. Steel inserts ensure secure bolt torque without material deformation.
  • Eliminates the risk of failure from weak OEM rubber differential mounts, ideal for high-performance and motorsport applications.

  • BMW 2 Series F87 M2 (2016+)
  • BMW F87 M2 CS Racing (2016+)
  • BMW F87 M2 Competition S55 (2019+)
