370Z street touring class ?
 

Is there a street touring class that a base Z + sport package can run in?

Str but you'd have to get skinnier tires. IMHO it's just not worth it.

You could run a square set up of the base rear wheels. 18X9 all the way around on a 255 tire. Doable but rough.

After seeing the moves for other cars to STU in the August Fasttrack I have sent yet another letter to the Street Touring board detailing why the 370 should be in STU and I encourage others with an opinion to do the same.

I second this. How do I formally request it?

You can read the Solo (autox) portion of the Fasttrack news (monthly rules update) here: http://www.scca.com/assets/13-fastrack-aug-solo.pdf

TLDR: Not enough people were competing in STU so they moved Mustang, Camaro, Genesis, and 350Z to STU in response to people asking for more tire. They also put C5 Corvettes in STU...

Then submit your letter via: SEB Letter Submission Form with category Street Touring and STU class.

Seems odd they move the 350 and not the 370. There's not a huge amount of difference there. Edit: and they differentiated Nismo from non-Nismo. These street classes are ridiculously specific :)

Does anyone know off hand are the 350Z a CS car?

Yes they are.

The Nismo 350Z actually includes seam welding the chassis. The 370Z Nismo, on the other hand, is the only car excluded from a Street Touring class where the engine and chassis are identical. It's one of my big points in writings to the board.

Currently you can pick between an STI or WRX in STU, you can have a C5 corvette (SS stock class) in STU, but a 370Z has to have 255 tires, 9" wheels, and run in STR; and if you have a Nismo you can't even do that. Straight to ASP :mad:

I'm running a 370z in STR right now. I'll be at Solo Nationals this year. I agree, if they're letting a C5 Vette into STU... The 370z should be let into STU.

BTW, the car is pretty competitive in STR... Even with just 255 tires. I'm on 18" wheels which even gives me more of a gearing advantage.

Ill have the car 90% setup for Nationals. We'll see what happens...

Pm me a copy of your letter. I'll tweak it and send one in as well!

I could be wrong but I believe this where you can make proposals for classes, and car etc. in Solo. SEB Letter Submission Form

That's correct. If we're all on the same page with our bulletin points... It will carry more weight.

Title: 370Z (All) to STU
Category: Street Touring
Class: STU
Car: Nissan 370Z

Request: Propose that all 370Z be moved from STR to STU. The factory wheel and tire sizes exceed the parameters of STR: in contradiction with the philosophy of the street touring class which should not require an immediately negative change. The weight is not competitive in STR, particularly with limited tire size.

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 now classed in STU. The 370Z is competitive with STU cars particularly those with which it shares ASP classing (Subaru WRX, Mitsubishi Evolution, and now C5 Corvette) without upsetting the balance of the class. 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.

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.
