Well I wouldn't want to flip my car over to look at this but it sure is awesome looking. Besides the fact this piece is FARE more beefier than the stock mount it's pretty easy to install too, fitment was perfect. At first I didn't really think that the OEM piece would fail, but hitting a hard shift coming out of a turn BANG!!! there it went. It was right after I installed my clutch style possi differential and front and rear urethane mounting bushings. The right side bushing boss is in three pieces now and in the aluminum scrap heap. I guess the flex in the OEM bushing never really stressed the rear mount. This 034 Motorsports rear differential mount is not going to fail under any hard driving conditions, maybe if you go T-boned by an 80,000 lbs semi truck it mite brake but I'm not going to try that. Great Job 034, I am going to be getting more goodies as my budget will allow.
