I just installed the SLP Torque arm for my 94Z M6 and it fits like a glove. However, I purchased longer bolts (Case hardened #8) for the bracket (1 and 1/2 inches) installation to the housing, and use Loctite Blue (medium strength) on these bolts. Removing the old rubber bushing at the transmission and installing the provided polyurethane bushing was somewhat difficult because you have to remove the rivets that hold in the rubber bushing. Other than that, the car seems to be smoother and no additional noise.

Note: In previous threads I read that the threading in the Moser housing did not go too deep. On my Moser unit, the bolts could be 3 to 4 inches long as the bolts thread through to an open space.

Question, what is a good street pinion angle for my Moser 12 Bolt with 3:73 gears?

Thanks!
