Product Details

This Wisefab Rear Suspension Drop Knuckle Kit fits the 2014-2020 BMW 4 Series (F32).

The Wisefab Rear Suspension Drop Knuckle Kit for the F32 4 Series replaces the factory rear geometry with a revised, motorsport-grade layout: dropped knuckle, upgraded arms, and optimized roll-center, camber-gain, and anti-squat kinematics. Built for drift and time attack, this F32 rear kit gives more grip, more adjustment and less weight than the OEM parts.

Every Wisefab kit is engineered in Estonia, used in Formula Drift, club drift and time attack, and fabricated from high-strength steel and CrMo, with every component available as a spare. It pairs with the matching F32 front angle kit.

Features

  • Dropped-knuckle geometry with revised roll center and camber gain
  • Upgraded camber, toe, and traction arm hardware
  • Bump-steer adjustability for track alignment
  • Reinforced knuckle construction for race loads
  • Significant weight reduction versus OEM
  • CrMo rod ends and spherical bearings throughout
  • Spare parts available for every component

Kit Includes

  • Left and right dropped knuckles with hardware
  • Upgraded toe, camber, and traction arms (as applicable)
  • Spherical rod ends and bearings
  • Installation guide
