SCCA AutoX - STU Class?
 

Is there anything in the rules that prevents a 370z with tires 285 or less from competing in STU? I could not find anything that only permits those vehicles specifically listed.

Stu is 3.0 liters or less I believe. I run STO for road racing.

It is not specifically listed so it is not ineligible for national competition. Regional cars that fall into any NOC (not otherwise classed) listing may compete in that class. Unfortunately the NOC listing for STU is as follows:

Sedans & Coupes NOC (non-
sports-car-based; 4-seat mini-
mum; over 5.1L normally as-
pirated or 2.0L to 3.1L forced
induction)

Being a 2-seat sports-car-based car makes the 370Z ineligible. And if you're wondering, STX has the same description but 3.1L-5.1L NA displacement.

Personally I think this is total BS. I have a hard time believing that we'd be destroying all the competition if they let us into STX. I definitely 370z gets the raw end of the deal in SCCA Solo classing. The real problem is, IMO, that the 370z is really "between" classes so the SCCA doesn't know what to do with it. It's either put it where it is now where we have to struggle to be competitive or drop us a class and then we'd have an advantage.

Now that Buetzer is running with Junior in SSP. Sell your nismo and run CS in a standard 370. That's the best class for the 370 at the moment. As others said, not legal for any ST classes.

:iagree:
I'm stubborn enough to stick it out in ASP, but it's going to be a long road.

I would expect it in STR, where the 350z is.

Excerpt the 350Z is not allowed in STR.

Yes it is.

Oops, my apologies. It is legal. Ironically that I ran a Solstice in STR for a year and an S2000 in STR for 1.5 year. :)
I guess no one really tried because of lack of camber adjustment and limitation of tire width.

There are ways to get camber in STR its really just the tire vs weight.

What he said. I have this one E92 M3 just killing me every time in ASP. But I keep going anyway.

No way no how will 370Z ever be competitive at a National level with well developed blown 4 cylinders in ASP. My 370 wasnt competitive with EVO's until I put supercharger on it. Essentially left my car in SP trim and put a blower on it to see if it was mostly power issue. It was. I went from being a second or two off all local EVO's in ASP to being even and beating them. Then there are old vettes in SP.

Its big reason Im going onto XP. At least with XP I'll have a car capable of being TTOD occasionally at local level and I'd rather be two seconds off top XP car than two seconds off a fairly stock looking EVO in ASP. I hate getting beat by EVOs regardless of class. So I built an EVO beater!

Id agree stay in CS with a base 370Z or BS in Nismo and your going to have best luck. Everything else we are screwed with SCCA

With all due respect, I somewhat disagree. I think he can do reasonable (bottom of the trophies) well in ASP, if he is willing to build an absolute rule book car. I do not think a 370z is going to be beat berry, grice, or miller.

Do you have links to any of the events you've run with the SC? I've been really curious to see how the extra power worked out for you.

fwiw Tim Moyer is moving to CS next year and Alex Jones has talked about selling the Solstice so he may or may not be in ASP next year so that at least takes a couple trophy contenders out of the ASP mix. :ugh2:

We just have different standards. Bottom of trophies isn't something I'd be willing to do if I spent money on absolute rule car. Way too much money for mediocre results. Frankly if you're a good enough driver you could probably scrape bottom of trophies in stock Nismo

Just saying these cars are though to make competitive in ASP.

Yeah. Here is one of more recent events. 27th overall at an event with so many national champs its sick. My car was technically a poorly prepared SSM car. 3000 plus lbs with stock width wheels. The car now is about 300 lbs lighter and has 12.5 inch rear wheels with 11.5 and makes 50 more hp. Just haven't had a chance to run it with season winding down. Drivers in our region are not slouches. Guy in SM EVO just in front of me is trophy level guy in past couple nationals in fairly well prepped SM EVO. Was couple tenths off Ford Gt too!

Here is vid of Ford GT I was in similar time bracket.

No, not even one of the resident aliens is getting a CS/BS 370 in the trophies at Nats in ASP. Not Heitkotter, Daddio, etc.

I've beaten Martin Kirz more than he beat me this year I believe, and he finished 6th. I also ran quicker times in the challenge at the toledo pro than Alex Jones did in his solstice, who was 4th at Nationals. There is no reason an ASP 370z should be slower than my car.

I had a pretty poor showing at Nats, which was somewhat unfortunate.

I do, however, believe that a 350z in BSP is a better platform than the 370 in ASP.

Best way to prove me wrong is for someone to build an ASP 370z. I was probably closest to SP class build when I hauled car to San Diego in 2011. My co driver was quite fast and neither he or I could get close to Berry Evo. Pretty much a slaughter.

SP 350 z has some advantages in ax over 370z in my opinion. I own both cars.

I'd put money on Brian getting darn close to back end of ASP trophies in a BS Nismo. My car in BS trim was pretty darn quick. Not much slower than SP trim. But then he isn't mortal

Trophying at Nats in a stock car in SP it not happening. I was 4 seconds (over two days) away from the last trophy spot in ASP. Only 1 second away from the last BSP trophy though.

I think that result tells you about all you need to know about the 370 in ASP. The car is not getting that much faster in SP trim.

Disagree with this also....:twocents:.

I was referring to the leaders who were another 4 seconds ahead of the final trophy spots.

I will continue my ASP effort. I will say, at Nat's this year, for me was like taking a knife to a gun fight. In all fairness I spent this summer working on the tough stuff like eliminating fuel starvation. In other words, I was in ASP with factory shocks and springs.

I did see potential in the Z. My first run was competitive, but as my tires came into their own, the track demanded more than my suspension could deliver, and the field walked away.

There's hope with....A lot of ASP sorting and driver improvements.

Full circle, CS is still the class for our cars. But as I stated, I'm stubborn and as long as I continue to climb in the results year over year, I can tolerate defeat at this level. I will (as would most drivers) be happy with a trophy at Nat's.
