Control arm bushings

At about 80K miles I started noticing some signs that my control arm bushings were wearing. For example, cracks in the road could cause the car to pull one way or the other. In the past I've taken this as a sign that my zero toe alignment combined with worn out front control arm bushings were allowing the front end to toe out a little when at speed. I've installed polyurethane bushing kits on numerous other vehicles so I decided to do that. Based on previous experience I initially tried Energy Suspension again. However their C6 Corvette kits do not fit a Z06; at the time, none of their sellers and only some Energy Suspension technical support members knew this!

Unable to find any polyurethane bushings I investigated Delrin. I found three options: Ridetech, Van Steel, and Borg Motorsports.

Of these only Borg Motorsports offers Delrin AF100 which contains 20% Teflon (PTFE) fibers which lubricates as it wears. Standard Delrin is expensive but the AF100 version is even more so.

More than half of the labor of installing polyurethane bushings is in removing the old molded rubber from the old hardware; and with its independent rear suspension the C6 Corvette is twice as much work than with my old SS Camaro. A nice feature of the Delrin kits is that all new hardware is provided; this saves a lot of labor.

Also remember that you'll definitely need an alignment when you're done.
