I'm looking at replacing the 7.5" rear on my car and at summit there are three similar kits, although I have no idea what the difference is other then gear ratio and the 28 or 31 spline, can someone educate me on this?
the kits are:

summit P/N:

FMS-M-4006-B373
FMS-M-4006-C373
FMS-M-4006-B355

My goal with this car is to race it on the road course on the weekends, while not quite a daily driver, although will see some road use.

My other question is I like to have a starting place to do all the suspension, I like the idea of a kit, so I've been looking at the road and track box from maximum motorsports, as well as the maximum grip box. Does anyone have any experience with these and what do I gain by going with the maximum grip box versus the road and track box.
Maximum Motorsports :: The Leader In Mustang Performance Suspension

thanks for the insight.

The only difference in the kits are that the b373 and b355 are 28 spline and have 373's and 355 gears, the c373 kit has 31 spline axles and 373 gears. And don't know about the maximum motorsports stuff other than the road and track kit has coil springs and a k member brace while the grip package converts you to a tubular k member and coil overs so the grip package probably lightens the car a good amount. The track kit also has steel lowers while the grip package has aluminum lowers.

For the MM stuff, depends on your budget, the whole package is nice, just realize you are talking about $2000 more bucks.

If money is no object, the more the merrier. And if that's the case, check out the griggs packages too.

If budget is an issue then I would say look at the packages from Steeda.
