Copied some of the info, but changed mine up some

I propose that all of the 370Z cars be moved from STR to STU. Almost all the factory wheel and tire sizes exceed the limits of STR. The 370Z comes with three different packages:
Base: Front tire 225/50R18 Wheel size 18x8
Rear tire 245/45R18 wheel size 18x9

Sport: Front tire 245/40R19 Wheel size 19x9
Rear tire 275/35R19 wheel size 19x10

Nismo: Front tire 245/40ZR19 Wheel size 19x9.5
Rear tire 285/35ZR19 Wheel size 19x10.5

The 370Z shares the same chassis platform with the G37 including engine, suspension, tire size, and wheel size. The different options offered for the 370Z are (G37 has comparable packages):
base: 332 hp @ 7,000 rpm Weight 3,278

Sport: Nissan Sport Brakes, Viscous Limited-Slip Differential
332 hp @ 7,000 rpm Weight 3,278

Nismo: Nissan Sport Brakes, Viscous Limited-Slip Differential, NISMO® Cat-back Exhaust System, NISMO® Swaybar Kit, NISMO® Aerodynamic body design, Tuned fuel map for
350 hp @ 7,400 rpm Weight 3,346

The 370Z is a market competitor to the Genesis, Mustang, and Camaro now classed in STU. The 370Z is already competitive with STU cars it shares in the ASP classing, Subaru WRX, Mitsubishi Evolution, and now C5 Corvette. The August Fastrack states, "One thing they all have in common is the ability, and need, to fit more tire than allowed in the lower classes," and this is exactly the case with the 370Z from the factory.

I also propose the 370Z Nismo should be looked at as an option package, not a different model. The 370Z Nismo package does not have any competitive advantage within the Street Touring allowable modifications. Any suspension, exhaust, or aerodynamic gain can be improved upon by a non-Nismo 370Z, with a lower starting weight.

The Street Touring classing is ment to fit between the current Sock and Street Prepared categories. With the current classing of the 370Z all of the models with the Sport and Nismo packages are exclude based on factory wheels and tires. Any modification beyond the stock/street limits force the car to move directly into the ASP class.
