I'm running Hoosier A7's in ASP.

Gotcha, that makes sense then.

Let my buddy drive my z at a bmwcca event. Looks like I've got a co driver for next season. :D

For anybody looking to modify their car from stock to ST or SP or SSM, I've got most of the parts you need, all of them barely used:
http://www.the370z.com/parts-sale-pr...ml#post3553460

Shameless plug for the car too: http://www.the370z.com/370z-sale/116...3-500-obo.html

For those of you that are trying to get the 370Z moved from STR to STU and haven't heard about the new push to open up boost limits in the ST classes, you might want to start writing your letters opposing it now.

Long story short, since it's not possible to verify the boosted cars aren't altering their boost control via ecu tuning there is a big push to allow open boost for the turbo cars in the ST classes. If this goes through you'll end up with STU being spec boost buggies which obviously would hurt the 370Z if it ever gets moved there.

How do you feel about the notion that allowing them to increase boost without allowing them to increase injector or tire size wont net them enough of a benefit? I spoke to a local stu competitor who estimates he will only be able to get an extra 15 hp unless he is allowed to supporting fuel mods.

Was talking to a past STU national champ out at nationals who's familiar with both the boost buggies. According to what he was saying, the STI won't gain much but the Evo's will gain quite a bit. This was based on him tuning a STU Evo at one point and then for grins playing with the boost tables to see the difference.

The other thing to consider is the area under the curve. Just because the car doesn't have huge gains up top doesn't mean the usable power and torque don't increase dramatically.

Yikes... this comes with me just finally getting my email that they're considering the letter I submitted (I'm sure along with others letters as well). I'm crossing my fingers to be able to throw a set of 285 RE71R's on next season and go to town with a nearly fully built STU car, but this would definitely cause problems nationally. Thanks for the heads up Gomer. Still crossing my fingers for STU as of now...

If somebody drafts the letter I'll send one in. I just hope they make one change at a time: let the z in, see how it does, if it's dominant then let the awd guys have boost next season.

I sent a letter in a couple weeks ago although it was hastily written so I wouldn't recommend anyone copy it. The short version of it was that if the boosted ST cars want to adjust boost tables then they need to go run in SP.

Honestly, as there is no good way to enforce the current "no adjusting boost" rule in ST the SEB will most likely act on that quickly.

Season closing event is tomorrow. It will be my second full season in the Z. I was really happy with the way the car drove but I know I need to make some improvements. For me I would like to try square 285 RE71 and a smaller front sway bar in the off-season. Once things get going I plan to buy some dampers, maybe midway through the season just for budget reasons.


What else is everyone planning on doing as things slow down?

Smaller front bar?
We run all year here so I just plan on putting these new tires to work

Smaller than what I have now which is the hotchkiss. One of our lots has a bit lower traction than the other so I wanna see how a smaller bar works out. I will probable do the tires first and go from there.

We have a winter series here that is a less competitive than summer. It's a good time to test things out.

The Official 370Z Autocross Thread
 

Well we don't have a winter in Florida, so there is no slowing down, my local club just started it's 2016-2017 season. There was another 370z out there today, he got me by 0.3s but we both beat the viper that was out there :)

My new oil cooler worked great, and the new tires felt great too, I'm pretty happy with my setup right now, at least until my skills improve ;)

From the email I received we may have a ruling on the 370z to stu proposal. Really excited to see how it goes.

And the 370z gets left in STR. :shakes head:

It would be curious to know what their logic is on why the 370z in STU would bad for the category. Anyone know someone on the STAC?

The scca hates money.

Wtf! But how??? That's such BS... looks like my competitive autocross days are numbered lol I was really hoping to pick up some 285 RE71Rs this year and compete in STU

Well the silver lining is next season just got a whole lot cheaper for me lol.

Is this posted somewhere? This is highly disappointing.

Thanks. So only 6 of us wrote in letters. I'm not sure how they think it's "not beneficial to the category". :/

Guessing from comments I've seen on another forum that they view it as:

370z>350z and 350z = current class winner therfore 370z = class killer

IIRC the 350z was originally in STR and the reason it got moved was that a top driver curb stomped the rest of STR in one. So apparently if we want the 370z in STU someone needs to do a full tilt STR build and put a top driver in the car and then curb stomp the field.

I thought Jason rhoades did/attempted that.

J-Rho did.

Here's what we are up against:

I personally don't see the 370Z getting moved anytime soon based on all this. Maybe if they open boost tables in ST for the turbo cars they'll have enough of an advantage over the 350z to open the door back up for the 370z.

Ugh this is frustrating... kind of stuck in a rut here. Still not willing to trailer/hoosiers for ASP but the car would get wrecked in STR, especially around North New Jersey/Philly. Some serious S2000 STR builds here.

Now to figure out what to do with this damn car...

Maybe find a codriver that could haul the Hoosiers to events for you and just change from street to race tires on site. Not ideal but it gets the job done.

Maybe Ill do an str build for my region. I really want more front camber.

Just go to ASP and enjoy the purple crack.

*researching 350z str builds.

It's pretty awesome how they won't move the 370 to stu and keep it in str but stu and str have essentially the same exact pax. I can't recall any class that has limited tire size Lower then stock like they did the 370 in str.
and why the hell is FS pax half a second faster then BS with cars like the new mustang and camaro, m3...

Until 370's start turning up in large numbers at NATIONAL events don't expect much to change. From everything I've seen in the short time I've been autoxing, the majority rules regardless of whether their decisions make sense. Look at the cars with favorable classing (pony cars, miatas, corvettes, the twins, and old shitbox hondas) and how many of them show up to national events vs the other cars with poor classing.

You can make a "what came first, chicken or the egg" type argument but it still won't change the fact that the 370 has poor classing and that isn't going to change in the near future.

I may be at nats this year. If not the year following. I think I'll be happy in bs since my local competition is pretty fun to race with, I just wish we had more factory camber. :(

The Official 370Z Autocross Thread
 

First Autocross since I installed my powertrix coilovers, they felt great. Any tips for adjusting the dampening? They are 15 way adjustable, I had them at 10F and 8R from soft and it felt pretty good, I adjusted them up to 12F and 10R and didn't really feel much of a difference, but time was slower by 0.20s both runs. Now I'm still learning, so the 0.20s could very easily have been the driver, but any tips appreciated :)

Is anyone still trying STR?

I think most gave up. I've heard ASP is fun though.
