Here is how mine look today. Just like they looked when I installed them myself back in December, no bulging, no gaps, car rides nice and tight, they work great. I have put the car through its paces and they have been able to take some abuse and not fail. Original control arms (I bought car new), car is not lowered, bushings purchased from Summit Racing May 2012.
I believe I read on this site ES redesigned their front lower control bushings once, correct?
Sorry to see these failures happen hopefully Prothane will come up with a better design to stop these failure.
