Who's making the move to STU?

ConekillerZ34 · 03-02-2020, 03:50 PM

Whew, finally got into the forums after a month of reading along.
Sold off everything, including my old 350z build, to go for a more competitive build and save some money at the same time.

Starting with a 2016 Nismo 6MT -- maybe not the optimal submodel for weight but it's the one that I wanted.

My MCS 2WR order is being built and I'll have an OS Giken on the way soon enough. I'm not going to get the higher-capacity housing, just to see if avoiding the displacement of sensors helps keep the ABS issues away.

On the cheaper side of the build, I've never had so much trouble deciding on an intake and brake pads before...

Posting a little build thread on reddit too. https://www.reddit.com/r/370z/commen...nismo_for_stu/

Welcome to the forum.

If you want to start a build thread here. Here's the section to do it in.

Got the seat this week and installed it today. I went with the Recaro RS-GK which is their JDM market seat. I'm slim and tall (6'2" 160lbs) but most of my height is my legs so I fit perfectly in the waist and shoulders. I mounted the seat on a sliding mount from PCI since I wanted the option of having co drivers of differing heights. With the seat adjusted for optimal leg and hand position, I have more headroom than with the stock seats.

Initial impressions are positive. I will have to wait for a few weeks before I can try them out at an event but next to the diff, this is looking to be the most influential mod on car.

Regarding my spl arm idea, that will have to wait. Maybe another arm option will spring up in the mean time as more demand for easier to use arms grows with more people building these cars.

Glamour shots as the car currently sits. Right now it's probably my favorite iteration of my car so far. All I have left to do before this season starts is change the oil and diff fluid and I'm thinking about installing another pair of helper springs in the front to get some more down travel. Cant wait to race this thing...

2pc Rotors installed last week, OS Giken going in tomorrow.

Did you guys see the 3/20 change proposals? Think they would spell the end end for us or am I being pessimistic?

I welcome everything except the turbo BMWs Inc the Supra. If they do let them in I wouldn't sell my car or anything. I'm way too attached. I would just build it for a different class. Maybe that new XS class is where I'll end up, or focus more on open track/time attack where it appears a wider a variety of cars can be competitive.

It would be hard to match the power to weight ratio of the new turbo stuff within the limits of stu.

If you're moving classes, I hear BSP is a ton of fun.

I'm def open to it. The only reservation I have is the logistics of r-comps. Maybe a tire trailer would be the key. We'll see.

Gomer, do you think we can manage 315 square in STU trim on 11s?
I've seen your involvement in other older threads about running 315s on the front on 10s with what appear to be unmodified fenders, but I was unclear if that was on a car that was lowered or not. Also, I ultimately suspect wheel fitment and offset to be a larger problem than tire in this respect but I could be wrong.

I mostly agree here, it's the addition of a bunch of new cars that would shake things up moreso than the other rule changes. New participants would be nice but not at the expense of the current participants, that's how I see it.

I don't wanna run R-comps to go to BSP

It'll probably be fine particularly if folks write in letters with nuanced thoughts, but I can't just sell this car so if things go that south I too would move into a different competition and away from autocross (which would be opposite of their goal of increasing participation).

the nice thing is we probably wont see too many even if they allow them in the class. its the same reason why there were only two cayman out there at nats last year. the car may be dominant, but they also perform really well stock with just tires. for a lot of owners it doesn't make sense to spend possibly $10k to do something unproven when the car can win in the street class. so if they let them in it will be 2021 season and then maybe another year or 2 before somebody develops a competitive platform and ruins everything lol.

gomer_110 · 03-24-2020, 08:02 PM

Mine is not that much lower than stock and the fenders when I was on the 315's were stock. I think the only real trick for 315's on 11's square is just getting the right offset.

fwiw I've moved on from the 315's to 335's on 18x12's. That's where you'll have to cut the fenders to get things to fit.

Hotrodz · 03-24-2020, 09:44 PM

I don't auto x but I run 315 square on 18x11 +18 with no modifications. I am lowered as well.

THIS is what I like to hear. I think the 11s are going to be pretty much a requirement for fitment and competitiveness if we have end up going 315 square, nice to know they'll fit if I can manage the camber.

Unfortunately we can't run SPL stuff yet so I hope we can reach any requisite fitment on Z1 arms.

What kind of front camber is needed to run 18x11 +18?
