So you really like the idea of the rear diff mount bushings. I mean who wouldn't? You get rid of that high RPM/hard shift sonic boom. That awful bump from the trunk, and you tighten up the rear end for better response. BUT there is one problem - your car is a daily driver, and you don't want super stiff race class bushings.
We're happy to let you know that we now have a solution for you. See, the thinking was simple. Take the great tooling we've got for the race class bushings, and just shoot some softer urethane into it. Thus, you now have the comfort version of the rear diff mount bushings. The shape is just like the race versions, filling those stupid voids on the stock bushings, and filling the gap on between the mount and the subframe, but with a softer, more gentle side. Just like the race versions these go for $40. Still less expensive than any others on the market.
