9 inch 
The one rear you will see in every race car is a 9 inch. They are not as effecient as the 12 bolt, but since every race team uses them (because of ease of gear changes), stronger parts are available. Call Strange tech support and/or Moser tech support, I'm sure they will be helpful. If you have a stick, launches are going to be HARD on all drivetrain parts especially if you hook. I just read where someguy broke his moser 12 bolt.

I wouldnt waste my time with Strange "tech support" you will talk to a sales man or woman not a tech...I just went through that. The Ford will hold up better but cost you some horsepower to turn it.
