Front Lower Control Arm Needs Replacing

On the prothanes, the front bushing would deform and fail on the trailing side (typically from under breaking). I put large washers on the rearward bushing to take up the gap and provide some sort of thrust surface for braking forces but that only bought me 20-25% more life out of them. The last set melted after some fall events in Arizona.

Dang. I have Prothanes on mine right now. Granted, I'm not even running at 10% of your ability, so they're probably fine, but all the more reason to replace them eventually.

I'll dig around and see if I have pictures of how I set them up to prolong life. Keep in mind I am also running 315mm wide R7/A7 and some slicks here and there to generate some punishing loads for the bushings. @ArizonaBOSS however also runs the same prothanes, and has never had an issue. So not sure the common denominator, maybe they had a production change at some point, etc.

Yeah not sure what is up with that, the Prothanes in my car are still intact after at least 3 seasons of abuse. I seem to be the outlier, however.
Thinking to convert to the 302S delrin bushings over the summer when the shocks are out for rebuild.
