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.
I thought about replacing bolts anyway since they are "one use only." Where can I get these bolts?
