I was pretty careful to not shut the car off hot - letting it continue to run to circulate oil and coolant until temps were down to ~205.

Went to do some front swaybar stuff, and found an explosion of smurf blood on the front undertray. Or maybe it was coolant.

It was all over the lower part of the radiator and frame rails too.

I know this car has a hard time staying cool, but this is just ridiculous. C'mon Nissan!:icon14:

Even when I was running my Z with the stock radiator I never had this issue. If I was you I'd be checking for a bad hose connection,etc. Also make sure you refill your system as this looks like it might be enough to actually cause you to be low on coolant.

My autocross runs this past weekend were in mid to upper 90 temps (3rd heat) and my oil temps never exceeded 220 degrees. We did 6 runs too which is unheard of here in the Colorado Region.

It was evident this had all come out the coolant overflow tube. Perhaps I'll top off with some Redline water wetter. Maybe it had been overfilled a little from the factory?

My car was showing outside temps of 102 at this past Sundays event. Oil and water temps all stayed normal and I shut it down between runs.

Is this something new for the 2012+ model car? is vlsd different than elsd? Once VDC is turned off, I have successfully did 360 at autox venue. I'm not sure why it would apply brakes if it's turned off.

Nice sig. I see Mark Labbancz's Black 192 Z (previous) :tup:

Got 275 on my 19x9 sport rims.

It's to minimize the inner wheel spin by applying brakes. All 370s have it

I've seen a few guys running 275/35/19 or 295/30/19 all the way around on the stock sport rims but has anyone tried a 285/35/19? Bfgoodrich is showing a 285/35/19 now on tire rack and with 18's being so hard to find at a decent cost I was debating running some torn up old sport wheels instead. Just curious how these would fit under the front?

370z officially moved to BS next season. Nismo moved to AS

Funny thing is, after looking at where the 370z's would have slotted into the BS results from nationals, the 370z would have actually had an even better showing. Unfortunately, this probably just means that in 2016 the 370z will be in AS and the Nismo in SS.:shakes head:

Just take the cats off and join asp :tiphat:

Already been doing that.

Peru Match Tour getting my a$$ beat by current and past national champions.

An ASP 370z should be faster than my car....which means it is not terrible outclassed in ASP.

...except at Pro's. Don't bother.

And this is the part that sucks as the Pro format is probably the most fun out of the 3 different formats.

Edited some auto-x video that I've been sitting on since spring :driving:

Anyone see these new AST 4100's for the 370z ? Any idea how they stack up again the MCS 1 ways for autox?

AST 4100 Series : AST 1-Way 4100 - Nissan 370Z/Fairlady Z

What's the widest front anyone's raced on? I'm looking to run a 285 35 19 on a stock rim, anybody know if it'll work?

I run a 315/30-18 on a 18x10 wheel up front for my ASP car. I know guys were running 295/40-19 hoosiers up front in CS before the change to street tires occurred.

Sissies....get your cutting wheels out and make a proper wheel fit up front (and back).

18x11 and 315:

Sooo LOL @ autocrossing with a 370 base with factory wheels and tires. Talk about zero grip anywhere. I went there to shake the car down before I start modding it, and by the first half run I knew EXACTLY where to start. Wheels n tires plz. The car has sooo much more to offer with a simple wheel and tire upgrade. Just venting fellas :)

Running on 285 35 19 Kumho XS square, my alignment rear camber is -1.7, toe is at .16. I ran my first event yesterday in my 370z, the lot we run at was recently re-sealed and a little slick but I have been running a srt-6 which has a little more torque and no lsd. My question is what are some of your rear alignment specs, the rear end was all over the place yesterday, front had a good amount of grip, I found running 36f and 33r was helping. My question is what do you guys recommend to get a little rear grip in the car, my rears are a little old, not heat cycled or worn out but ill go to a 305 rs-3 next which i think should help. What may you guys recommend to me? alignment specs maybe?

going from 285's to 305's would already give you a nice change, especially with rs3's. I'd mount them first and see how it feels, and if you still aren't satisfied look into changing around the alignment. What are you running for suspension and swaybars?

I am 100% stock, first autocross in the car, just felt more loose then it should have been to me

Sticky tires and learning when to modulate the gas. You could do a front sway bar too, but I'd suggest getting a good feel for the car without one for a season first. Also, what was the temp where you were? That can have a drastic affect on tires.

I was running a275/305 rs-3 setup and though it felt pretty good, but then I changed to stock 245/275 zii's and it was so much better. I'm stock as well but planning on doing shocks and a front sway bar next season.

hahaha I JUST went through the same thing in my Z! I myself am trying wider wheels and tires first before anything else. I'm considering an 18x10.5 wheel and 275-285 wide tire setup all around, or a "square" setup as i've seen it called.

I for one would like to see someone finally do a rulebook 370z for ASP....

Slowly but surely I'm working on it. Unfortunately the bank account only goes so far for any one off season. Hopefully after this winter the car will be what I at least would consider 80-85% rulebook.

Still trying to decide on whether ditching the factory Nismo wing for a proper spoiler is the way to go or not.

Do aero last...

Since I was gone for most of the year I only had the chance to run two events in the New Z. PSS's are not the best but it's all I have right now. It was nice running a stock car again since I was able to pick up on some bad techniques that I had to quickly fix. The PSS's did pretty well in the last event since it as cold but I'm switching to Rivals next year. Who here is running ASP? I'm planning on running that next year. Took a 2nd and 1st in my last two events in BS but it looks like the Nismo is going to AS next season.

I'm running ASP. Will most likely being doing Toledo, Wilmington, and Peru national events next season and hopefully a trip out to Lincoln assuming I can find a way to get the car out there that doesn't include driving it out.

What did you do to make the car competitive? For next season 18" wheels and tires is the main goal and I want to run a 275 up front min. The Z is stock right now minus a oil cooler and exhaust. I was glad that I was beating up on camaros and a boss after only two events but I did notice a decent difference in how the Nismo handled over my old one.

I run 315/30-18 Hoosiers on all 4 corners. Car is full breather mods, Uprev tuned, upgraded drivetrain (LSD, flywheel, etc), 2 pc rotors + carbotech pads, upgraded sway bars, front upper control arms, AST single adjust dampers with the factory Nismo springs. The shocks and springs will be getting replaced this off season along with the addition of adjustable rear spring perches and camber arms.

Which LSD did you go with Gomer? That may be next on the list for me. I'm running ASP as well. Thankfully I've barely been able to hang onto my cars daily drivability. Just did KW coils and a new clutch/flywheel this season so far. I know it's not the best coilover for racing but the adjustability is nice and it's been a good compromise for street driving as well.

I have a quaife in mine. In the grand scheme of things I probably should have gone with a clutch type LSD but for now I'm not too worried about it. Still need to do a lot more work on the nut behind the wheel before I worry about the finer details.

Haha same here. I keep saying that I need work as a driver. I'm lucky I haven't modded the car beyond my own control or abilities. I was worried about that for a while but I seem to be controlling it well enough. Just have to refine my techniques now.

Luckily I have some top level talent in my region (unfortunately none are ASP) so at least on index I have a pretty good gauge of where I stand. Additionally I had the chance to go head to head with Aaron Miller and the current ASP national champ (can't remember his name) out at Peru this summer. Unfortunately it wasn't until after that weekend that something just clicked and I was able to drop a few additional seconds on an average 50 sec course.

Those of you running a 295 up front, what size wheel and offset are you using? I am leaning towards a square setup for next season but keeping the stock Nismo suspension for now

Front: 18x10 +30
Rear: 18x11 +18

315/30-18 Hoosiers on all 4 corners. In all reality the 315 wants a wheel wider than 10" to be happy, but it does work on a 10" wide wheel.

Also don't waste your time with 295's just go to the 315's and call it a day. When I made the switch it was remarkable how much happier the car was.

18x11 315 on front and 18x12 335 out back is where you need to look for a 370z
