Rear Roll-Over Strut, BMW - G42, G2X, G29, A90 Supra M Sport

This is the rear Roll-Over Strut (aka lower Spring Arm) used on the G42, G20, G22, G29, A90 Supra with the optional M Sport (option 0704) or Adaptive M Sport suspension (option 02VF). BMW calls it a Roll-Over Strut but everyone else calls it a lower Spring Arm or lower control arm. It's the main arm in the G2X rear suspension, cradling the spring and providing the mounting location for the bottom of the rear shock. The inner mounting bolt is also the factory camber adjustment. Inner bushing is included but outer bushing on the carrier is sold separately

This is a Genuine BMW G2X M Sport lower spring arm with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.

Inner bushings for this arm are not available separately. A link to the outer bushing is below.
