370Z from STR to STU... again.

takjak2 · 07-03-2017, 11:30 AM

Gave up on SCCA a long time ago. Good luck.

From my 2013 letter:

The factory wheel and tire sizes exceed the parameters of STR: in contradiction with philosophy of the street touring class which should not require an immediately negative change.
The 370Z shares the same platform with the G37 including engine and suspension. The 370Z is a market competitor to the Genesis, Mustang, and Camero all classed in STU.
In the 2013 August Fastrack, the stated reasoning behind adding a slew of RWD cars to STU stated: "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.
Additionally, the 370Z Nismo should be treated as an option package, not a different model. Unlike the 350Z Nismo (which includes chassis stiffening), the 370Z Nismo package does not present any competitive advantage with Street Touring allowable modifications. Any suspension, exhaust, or aerodynamic gain can be improved upon by a non-Nismo 370Z with a lower starting weight (similar to a preference for non-STI WRX where both are allowed in STU). No other model of car is excluded from a Street Touring class where the engine and chassis are the same.

Some great additional points in there tak. Thank you. I don't have much hope... but now that I'm finally purchasing Hoosier A7's for my street prepared 370Z I'm dead sure they'll make the move to STU. LOL

Not yet, but based on a few things not counting that out for next year!! Oh I can't wait for some purple crack. I have 315/30r19 rears (squeezing them on OEM rear rays for now, 19x10) and getting another set of rear rays and 295/30r19 fronts. Not quite sure if I can fit a 315/30r19 on the front... you run 315/30r18 front A7's right?

Yep, 315/30-18 in the front.
