BMW E46 M3 Rear Subframe Reinforcement

Vorshlag developed these reinforcement panels for the E46 M3 factory tubular subframe. When used with extra large tires, high power or high aero loading these are known weak spots. The four pieces included in this kit can be welded in place to reinforce the rear differential mounts and the rear swaybar mounting locations, as shown. The E46 M3 subframe can be added to any E46 chassis model along with it's accompanying differential, axles and suspension arms.

  • Welding and some fitting is required
  • Ideal for highly stressed race cars
  • Prevents future damage
  • Recommended to be used with stiff bushings
