Mustang upper rear control air bushing failure(s)

[ShadowBolt]

Hey guys, hoping for some guidance. Last year we replaced both driver and passenger rear upper control arms because the rubber bushing inside the control arm pushed all the way out on one side. We then installed a Maximum Motorsports panhard bar and their rear upper control arms before our first event this year. We've had two NASA events this year and we've already pushed the rubber bushing out of one side (drivers) where it contacts the pig tail ear thingy on the axle housing. I believe last year the failure was on the other end, not at the axle housing. Have any of you Mustang drivers had this kind of failure more than once a season? Any suggestions on whether we should replace the control arms again or try a poor mans 3 link. Any other options out there?

Dave,

I go through an upper control arm bushing every four or five events. I only lose one side the other side never wears out. When I ran the panhard bar it was twice as bad. Try the car without the panhard bar. The control arm bushings will last way longer. Some of the fastest guys (Aaron) does not run a bar. We run sphericals in the housing.
