Square all day.

Thanks for the input guys, looks like squared is the consensus. I was going to buy the Nismo rims since they are light and good looking.

I just meant I don't care if a particular mod bumps me up a class as long as it makes me faster, of course I'm trying to win ;)

I think a lot of us thought like this at one point. The cool thing about autocross is that there is room for builders and drivers to both have fun.

That being said most people enjoy the sport much more when they have a car that is classed favorably.

A few weeks late to the party, but I wrote up my own letter supporting the 370 in STU.

Thank you, especially coming from the 2015 STU national champ! Haha I posted this on the Z track group on FB and a 350z guy got so butt-hurt over it. He said he would promptly write a letter in return countering the move. I think it's fair though.

What a hating-***-bitch.

I was expecting this when I was in STU with my 350. The 370Z should not have to run bicycle tires in STR. STU makes much more sense.

IMHO if they can lump multiple generations of pony cars into the same class why can't the 350z and 370z get lumped together.

agreed! I don't know when the decision will be made but I want this to keep getting pushed so I can be closer to a competitive car in the right class. ASP is a bit too much for me considering I have no way to get slicks to an event and don't see myself getting a trailer/hitch anytime soon (or until I buy a house this year). I would be glad to just purchase some 285 RE71's, throw them on my square rear Ray's setup and compete in STU. The car is mostly built for the class now anyways. I'd have to do minor things to back track into a street touring class.

I wouldn't plan on driving any real distance on the new batch of "200" TW wink, wink, tires.

They wear ~ twice as fast as real 200 TW tires.

Is it any worse than driving around on R888 or NT01'something? Lol cause that's what I'm reduced to right now. My front nt01 are finished with tomorrow's autox and I have a set of slightly used direzza zIIs to drive on for a while.

I'm guessing it's just like driving around on NT01's or any other 100TW tire.

Racing all alone in B Street at the Wilmington champ tour this weekend. I think there's one other 370 here in ASP, gomer_110?

Today (Friday) was the test and tune. I got one run in the dry and then they delayed for lightning. Later got several runs in the rain. The challenge will be if it starts raining, or if rain starts clearing when we run.

Running bs out here in co.

How prepped is your car?

Yeah, it's me running in ASP. For once ASP actually made class...until the STI with 2 drivers lost it's motor during test-n-tune. Now it's just me and a co-driver in ASP as Miller's are going to run their Evo in SM. :shakes head:

As much as it can be legally without high dollar shocks. Konis, hotchkis front bar, re71s, downsized wheels with +7mm offset, cat back exhaust, k&n drop in filters.

The course is going to favor the vettes. Lots of long straights starting in the low rpm range. Possibly 3rd gear several places. Someone measured it to be about .9+ miles. I'll see what I can do.

I still have a ways to go. I plan on getting a set of ast so that I can expand the system if the car gets moved to stu.

What are your thoughts on the Hotchkiss bar? I ran it at a few events and hated it but I'm not so sure I want to drop down to the Eibach.

I love it. What didn't you like?

I feel like it is much harder to initiate rotation with the throttle. The car just wants to scrub now, even with square 275. I only have 3 or 4 events on it so I don't want to rule it out just yet.

What shocks and shock settings do *you have?


Sent from my iPhone using Tapatalk

Still stock in that department. All I have so far are square 275/35 re71 and the sway bar. Stock front camber on my car is -1.1 on the right and -.6 on the left.

I seem to be the only one of those I have polled who feels this way so it definitely seems to be my driving.

I'm going to have a buddy who is a bit quicker than me co drive at an event this weekend to see how he feels about it too.

Thanks for your help.

Koni yellow shocks made a huge difference on my car. That'd be the next thing id do. Good luck

That does seem like a good idea and safe for if I move the car. Thanks for the suggestion.

Video from Wilmington. I had a bad day 1, and better day 2.

That looked like a long *** course. A lot of fun though (get it, a LOT)

It was TOO long and definitively pushing the speed limits on how fast a autox course should be.

Will never understand why Wilmington courses have to be so damn long. A 60s course in a CS car is plenty long. Just because you can make a massive course doesn't mean you should. :shakes head:

Probably because they think it's what people want. A lot of newcomers see autocross as a safe alternative to tracking their car. A long course might appeal to the person looking for seat time rather than competition.

I think average course length at our events in right around 50-60 seconds at our largest venues.

The Official 370Z Autocross Thread
 

It was .85 miles long according to my gps data. The problem imo wasn't necessarily the length as much as it was how it rewarded the cars with better low rpm hp/tq. You dip down to 23-35 mph 8 different times and accelerate, full throttle to 60 or higher. A normal Autocross it's maybe 1-3 times that happens. Also the start was a drag race start to 40 mph.

My comment about the length was more due to the flow of the event and the fact that IMO there's no reason the final heat should have been finishing ~7pm on Saturday.

It was pretty apparent though that the course designer was a CAM-S Corvette driver. :ugh2:

The Official 370Z Autocross Thread
 

Haha. I was starter for 2nd heat. I sent them as quick as they (timing and course workers) could keep up with. About 18 seconds between cars. Loooong day for sure. But that's just how long it takes to send 360 cars. They should maybe stick to their 325 limit.

360drivers x 20sec/driver x 3runs / 60sec/min = 360min

Then 15 min x 4 worker switch = 60min

30 min mid-day course walk

~45 min for delays and re-runs

You're looking at about 8hr and 15 min once cars start rolling, which on sat was 9am. That puts us ending at 5:15 pm. Hmm what am I missing? Maybe the other starters weren't as aggressive as I was. If u change that "20" sec to "23", that adds an extra hour to the event. Crazy.

Fun from this last weekend at the Wilmington ProSolo.

Fastest Left Side


Fastest Right Side

Just a quick video my buddy took from outside the car, this was a for fun event last weekend. My car is starting to work pretty well overall, the r888 were not even close to getting up to temp this day. It was fun taming the beast non the less. Apologize for the video quality and the wind.

Anybody ever run 275/40/18 I found some cheap and won't run them but twice or so

The Official 370Z Autocross Thread
 

I've kinda asked this question before, but I'm getting ready to pull the trigger on some new rims. Should I go 275/35/19 front 305/30/19 rears or try 305/30/19 all around. Either staggered nismo rims or rears all around. Planning to eventually go FI so I want 305s in the rear.


Sent from my iPhone using Tapatalk

If you're modded is go 285/35 and 325/30 on nismo wheels. Get as much/sticky tire as you can get.. I run a stock class so I have to be within stock wheel specs

More tire = More better. 315's or wider all around.

Thanks, now I just need to figure out if the Nismo rear rims with 305s will fit on the front and not rub, I have carbon fiber fenders so I can't pull them


Sent from my iPhone using Tapatalk

Check the tire section, there's a guy running 285 up front and he's got a bunch of pictures. I don't think you'd want much wider.. 295/30/19 fit on stock wheels with Hoosiers so they may work

315/30-18's on 18x10's will fit up front.
