We've updated the design on our BMW  e21 and e21 Rear Trailing Arm Bushings!

...When installing E30 Weld-in Rear Camber and Toe Correction Kits, solid rear trailing arm bushings can, at times, bind on the trailing arm mount brackets. We have addressed this issue on our newly designed Condor Speed Shop RTABs by adding a radius to
the ends of the bushings...

These UHMW bushings with Aluminum Sleeves, will stiffen the rear trailing arms while maintaining the stock suspension geometry.

For BMW e12 and e21

Kit includes a set of 4 trailing arm bushings
