Are there major differences between these two models? I know the sport comes with the different rims, but is that all?

 

The G37s has the sports package, which includes: 19" rims, LSD, thigh support in seats, akebono brakes, different front bumper, sport suspension, among other things.

The g37x (AWD) has all wheel drive, but omits the sports package. The g37x also is only available in 7AT, no manual.

 

G37x also weighs 300+ more pounds.

is there a g37awd s

 

Nope, the S has offset wheels, you'll never find an AWD from the dealer with offset wheels and tires. It puts a strain on the AWD system, so they'll never make it at least with the same wheel and tires as a regular S model. Maybe something like the Sedan, they make a xS in the sedan, but it has the same wheels and tires front to back.

 

do you mean staggered wheels?

 

Yeah, what he said.
