Dave, I have a 6 speed in it already and plan to get that diff as well haha with a nice 3.9 ratio. I've heard they can take nuclear bombs. I have yellow stuff pads in there and they are pretty good with Michelin pilot sport 3s, these are savage . I'll move up to carbon Pads or probably 4 pot willwoods. It's only early days!
You know yourself, the parts list just gets longer and longer.
