Thanks for the replies. This is the first year we've tried the panhard bar, after not changing any suspension components of the car the past 7 seasons I wanted to try something different in hopes of getting closer to our Camaro front runners. We really didnt examine the upper control arm bushings after each event the past many years so I cant say for certain how many arms we'd go through per season if we checked. Thanks again, we'll have to replace or change our current setup before our next event in 3 weeks.
