Who's making the move to STU?

Might be a good idea not replacing the diff cover. Though, it seems that every one of us that does have the ABS problem have the Z1 cover. So, maybe the others don't have the issue? I'm really not sure.

That may be the case, as it should only depend on whether or not the covers displace the sensors. This feels bad in general since it seems like Nissan could have just avoided putting the sensors there.

That said, since I have a Nismo, I already have a finned cover so I'm just going to pass on the extra capacity. No reason the OSG needs a different cover for fitment, right? I had one in my 350 without a different cover so I assume it doesn't matter.

Take this for what it is. I have the OS Giken diff, the Z1 diff cover, MAM diff cooler, and Diff temp gauge. My diff lube capacity almost 3 liters. I do trackdays. You auto-x guys don't spend that much time on the course as the track guys. My observations with the diff temp gauge. It takes about 12 miles on the road to start heating up the diff lube. It will read between 120F to 140F. I can drive on the highway at 80 mph for 4 hrs non stop and the diff temp will be between 250F to 265F. 20 minutes on the track will send the temp over 275F. All of this is with my diff cooler turned off. With the diff cooler on. My diff temps stay under 220F.

My point being about the extra capacity of the Z1 cover. I think you would be fins without it. Now if you do trackdays too. I would get it.

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.

ConekillerZ34

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.

ConekillerZ34

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.

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.

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.
