I'll concede the springs point. Completely forgot those were different.

The sway bars argument I can't agree with though. Street class allows replacement of one, so replace the front bar with a stiffer one. This still leaves the rear bar which is stiffer on the Nismo. I would argue that this is actually penalizing the Nismo as it will make it more tail happy and harder to power out of turns.

And let's not forget the Nismo is actually heavier than the base+sport. Yeah it has 18hp more but that is mostly due to the Nismo cbe which is something the non-nismo guys can replace anyways in the street class.

Also does anyone have any actual real life data showing the Nismo's superiority over the non-nismos is autox? If you do, please share.

The extra .5" front wheel width makes the 305 a reasonable choice - that's a huge advantage even if everything else was the same, which it isn't. Then there's the '15's shorter final drive...

If the regular 370 got moved in with the Nismo in BS, I probably would have traded up. I mentioned this on another forum, which was probably a mistake, as it wouldn't have surprised me if the Nismo had been overlooked if I hadn't mentioned it.

Got a dark cloud of classing over my head, sorry it sprinkled onto the Nismo owners too

I think I'll just have to agree to disagree on this issue. IMHO until real world data is available, a car (any car, not just the Nismo) should be classed on the soft side. I'll be the first to fall in line once a car shows dominance in a class to have it moved to a higher class. fwiw I define dominance as multiple drivers all doing extremely well in the same car not just one great driver walking away from the rest of the class.

So, I am not shocked they moved the 370 to B Street. I feel worse for the Nismo, it is officially buried now that it's in A Street. But, a Base 370z with sport would not be competitive vs. a Nismo, so if I must drive in BS I'm at least glad it wont be against a Nismo. Having written multiple letters to the SEB on this classing issue and others I am convinced they don't listen to anyone but those who have enough clout as a national winning driver and/or have been active at national level for so many years so as to be known by name. It appears that at the national level Auto-X is being ruined by politics and popularity contests...very sad.

Over the past 6yrs of reading fast track and rules updates, etc. only about 33% of the time does the SCCA SEB seem to make a any rules decision that makes sense. Most the time only if the supporting data is so overwhelming that a raving internet fan boy can't refute it. Makes me think that we have boating enthusiasts making our car classing decisions. /end rant

All that said, I don't think the 370z is overwhelmingly outmatched in BS...unless it's a Pro-solo now that the Audi TT is a BS<sigh>. I just hope that the B Street PAX gets a little softer so I at least have a ice cubes chance in hell at regional events next season.

You must not know the politics at scca. It is quite pathetic

wstar · 10-03-2014, 03:14 PM

Yeah SCCA's classing system and the politics of it is what drove me from wanting to put my Z in their road-course classes, ever. I was planning to hit NASA instead and just do their ST[321U] system that's based almost entirely on hp:weight (I don't think NASA does competitive Auto-X, though). On the other other hand, I'm now really thinking about ditching all the mess of modding a production car and just doing a spec racer class in SCCA, like Spec Racer Ford, maybe sometime next year. Way cheaper and easier in the long run.

So, do 18's fit over the Sport brakes? Who's got the best price on an OS Giken? Will wait till Oct 20 to start buying stuff, but it's looking like STR is the place to go...

Without the restrictions of Street class, it should be relatively easy to find good 18" wheels, I'd check Forgestar. The one guy at Nats who had 18" wheels in CStreet was on Forgestars.

I'll send you some OS Giken contacts on FB for the diff.

Also make sure you talk to Mike Carpenter from Utah who already has his Z built for STR. He has a thread on this forum detailing his build: SCCA STR 370z Progress Thread.... It can be done!

And as soon as you buy wheels and tires they'll move the 370z to STU.

You could just go play in ASP. I hear running the purple crack is a good time.

j-rho · 10-03-2014, 10:24 PM

That's why I'm waiting till the 20th - last chance to publish 2015 class changes.

Re: ASP, already have a car that needs trailering. The Z was meant to be the drive-it-there-and-back ride.

03threefiftyz · 10-04-2014, 06:06 PM

A move to STU would be even more of a reason to build the 370 for ST. That said, not going to happen. The evo/sti guys are already in a fret over the 350 and the 370 is a better car.
