The Qualifier - E36 Poly Subframe, Differential, Rtabs

The Qualifier kit gives you everything you need to take control of the streets, or shave off seconds on your lap time.  The kit includes rear subframe, differential and rear control arm bushings for your E36.  

Revshift polyurethane bushings completely replace the OEM rubber bushings on all E36 cars except for the 318ti. These bushings stiffen the suspension improving the vehicles handling capabilities.

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:

• Rear subframe bushings
  
• Differential bushings
• Rear trailing arm bushings.
