The hex head bolts that connect the guibo to the defferential are torque to yield bolts and should be replaced. When I went to a local fastener shop to try and find some upgraded bolts they reccomended going with a softer bolt that would have a little more stretch.

The person working there stated that the factory 10.9 bolts are so hard that they will snap. He mentioned having a similar problem with a mercedes. I figured I'd give the grade 8 bolts they mentioned a shot. Haven't been to the track yet though.

I'm hoping if there are any issues ( I haven't had any yet but was swapping gears) a bent bolt will be better then a snapped one.
