The Rumble Strip - E30 Poly Subframe, Differential, Rtabs
The Pit Lane kit gives you everything you need to take control of the streets, or shave off seconds on your lap time. The kit includes subframe, differential and rear trailing arm bushings for your E30.
Revshift polyurethane bushings completely replace the OEM rubber bushings on all E30 cars.
Offset control arm bushings came stock on the E30 M3 and 1995 M3. Non-M3 E30's and E36's benefit from these bushings because they increase the caster and improve the vehicle's handling and stability.
- Improves handling
- Will not wear out like OEM bushings
- Properly dampens suspension components
This kit includes:
- Subframe bushings (choose OEM or Riser Kit)
- Differential bushing
- Rear trailing arm bushings
Note: The riser kit is recommended for lowered cars to reduce camber. Each riser kit includes a differential stud kit
