This is the rear Roll-Over Strut (aka lower Spring Arm) used on the F22, G42, F30, G20, F32, G22, G29, A90 Supra. 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 F3X/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.
For G42/G20/G22/G26: this is the arm used on cars without M Sport (option 0704) or Adaptive M Sport suspension (option 02VF).
This part is manufactured by an aftermarket supplier of European auto parts, including many suspension components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
This latest part number replaces or is compatible with BMW part number 33326867540.
Inner bushings for this arm are not available separately. A link to the outer bushing is below.
