Kurt:
You can use the factory Motorsport LSD or one of the 4340 chromemoly-cased Guard ones. The latter ones are FAR stonger than the factory units and would be strongly recommended for your application. Please let me know if I can help.

Hi Kurt:
I have the Guard units in stock and they require a check of the pinion depth and ring gear backlash. Its easy to install but any adjustments require total disassembly of the transmission. These are FAR better than the Quaife ones as these torque-sensing type LSD's freewheel (open) under trailing throttle and do not provide the gains in handling that the clutch-pack style LSD's do. Its a very big difference,...  If any corrections are required, you'll need a good selection of the factory shims.

Call Paul Guard at 1-888-89GEARS. He will let you know what will best suit your application. Super helpful guy too. As Steve said, you will probably want the cromoly one sice you are putting out a fair amount of hp.
Cheers, James
