In our quest to build the ulltimate upgrades for your automobile, we spend an lot of time in R&D on our parts. Sometimes we even go back to revisit a successful design to make it better, and that is what we have done with our Caster Adjustment Bushing kit for the Legacy GT and 08 WRX models. We have changed two small, but important areas of the design. 

The most obvious change was to the outer steel sleeve that our Polyurethane bushing resides in. A small lip has been added to the top, preventing movement by the CAB unit. It has been found that it was possible for the CAB to pop out of the control arm under very heavy usage. This lip prevents it from happening.

The second change is harder to see, as it's on the inside of that metal sleeve. The addition of a serrated finish to the inside of the bushing sleeve keeps the bushing from ever popping out of the sleeve itself -further increasing the safety of this design!

These new CAB units are now available from AVOturboworld or it's dealer network.
