that's about where my uncle lived in west orange. he was a trainer for the devils for a few years so I would go down for pens v devils games then go out with him and players after the games and whatnot. it was def a good time.

You'll typically get into 2nd gear and just hang there. Come out and race on Sunday!! It's gonna be a good time man.

Well I never run in auto-x cause those events here nobody are doing it from the earlys 2000 :shakes head: But my first run in the Z was a time attack event in January and the gears that I most use 3rd and 4th... sometimes 2nd and 5th on the drag straight... But I think in Auto-X if the track is a short configuration the gears that you are going to use I think are going to be 2nd and 3rd gear.

I plan on running if they let me run lol

i'll go kiss up a small bit if they are really crossed with me about the sound but I am not swapping out my exhaust just for a small couple hour event. not worth my time.

so if they allow it i'm running. if not then fuck em :tiphat:

My first 5 events were on my stock yoko's with a plug in the rear tire. I was safe and it held like a champ. It was done by an ex con who had a used tire shop down the street. :tup:

Alternatively, if you want a little more life out of your tires and don't mind not having the absolute fastest tire, I'd go with Hankook RS3 V2s, same size (or maybe 285s on the rears)

Thanks for the recommendation dude! :tup:

So what's everyone running alignment wise? I just added a little camber in the rear to -2 and fronts at -1. Toe I kept close to zero -.15.. anyone have any better recommendations?

gomer_110 05-03-2015 05:36 PM
Camber:
Front: -2 to -3
Rear: -1.5 to -1.8

Toe:
0 all around

I run ASP though, so getting more front camber via aftermarket upper control arm is allowed.

Yeah, I wish some eccentric bolts would work but I'm gonna stick with BS. I had to up rear camber a little due to outside rear tire wear. Anyone having this issue?

cjwsrt6 05-06-2015 07:17 AM
What's everyone's recommended fluids? Brake, rear diff and transmission?

For the Brakes I use the Motul RBF600 and for diff and transmission Im going to use the Redline 75w90 for diff & Redline MT-85... Im going to do the Diff & Tranny fluids change this month.:stirthepot:

I run ATE super blue for clutch and brakes, royal purple diff and tranny. mobile 1 oil, I've ran this for 3 yrs now and everything has held up pretty well. The main reason is I get a discount for these fluids, so more money for go fast parts.

cjwsrt6 05-23-2015 04:09 PM
Has anyone ran the re-11 285/35/19 on a stock front rim? I know the kumho xs did but would like to be sure before I purchase

j-rho 05-28-2015 02:57 PM
Learned a couple interesting things this past weekend:
1. Disabling the yaw sensor (a Street/Stock-class allowance) also disables traction control.
2. Trying to disable traction control in the middle of an autocross run is very difficult :)

Where do you plan on running FP? I know all the noise ordinance for Philly Scca and NNJR scca. Philly is 98 db max at 50'. so, at 95 db you get a warning and 97 it's a fix it. NNJR is similar. You should run philly scca.

I'd listen to him if I were you. He may know a thing or two about our cars and autox ;)

I did. for year and half. I honestly had a lot of fun but felt 285 might be bit too much for front. 275 I'm feeling a lot better. I actually have a set of 285-35/19" re-11 sitting in garage. Maybe have 7000-8000 miles left on them. I'm going back and forth on selling them or keeping them.

how do you disable yaw sensor in our car? shouldn't with VDC off, you're pretty much turning everything off (except abs)?
2. most frustrating feeling ever. We have all done it haha

I buy the Kumho KU-39 in 255/40/18 & 285/35/18... now just waiting for the damn wheels to install everything :shakes head:

What does everyone mean by 285 is too much upfront? I keep seeing people stating this. I've always been taught to run the widest front tire with whatever holds the rear to help turn in and if it's enough front tire you use less brake and the turn scrubs scrubs little speed

j-rho 05-29-2015 12:55 PM
To disable the yaw sensor, you can cut the green wire going to it (it's the Bosch sensor in the center console). Or you can wire up a switch - I used a factory seat heater switch to enable/disable mine.

Re: 285s in front - tires work best on proper width wheels, and ideal is usually when wheel width is about the same as tire width (1 inch of wheel width) = 25mm of tire width. That means a 285 tire works best on a ~11.5" wheel, much wider than the stock 9's. That doesn't mean 225's (~9" wide) tires are best on the stock front wheels, only that you're getting to a point of diminishing returns. The tire's construction also matters a lot too - something like a Hoosier A6/7 is designed to work well when "pinched" on a narrow wheel, but normal street tires aren't.

gomer_110 05-29-2015 08:23 PM
fwiw I run 315/30-18 Hoosier A7's on a 18x10 wheel in the front. Turn in is great. Unfortunately, this doesn't help you street class guys much.

They rub the fender at all? What offset wheel? I fit a 295 A6 on the front with the stock Rays but haven't tried a 315 front. I have a set of Enkei PF01 18x9.5 +35 and 18x10.5 +15 that I run nitto NT01's on right now.

gomer_110 06-20-2015 09:19 AM
No rub that I've seen. Wheels are 18x10 +30 front, 18x11 +18 rear with 315/30-18's all around. Currently at ~factory ride height with -3.0 camber up front although I know as little as -2.1 still doesn't rub.

PharmDZ 06-20-2015 09:34 AM
Hmmm I may have to try out a 315/30r18 square setup once my nittos are done. I'm curious to see if it'll fit. I'm running -2.5 front camber, dropped maybe an inch on KW V3's. It'll be a bit of a pinch on 9.5" rims but it may work. God knows the car needs all the help it can get up front. lol

Bump.

Pretty cool weekend. We had two 370 in the top 3 in BS. There was also a pretty sweet looking, Boosted nismo running in ssm.

AK370, it was nice meeting you. You drove well man. Congrats on the 1st place.

How did the car feel today?? I was down in South Jersey - almost beat the evo thats always #1 in my class today =/ coned my last run which would have put me .002s ahead of him. Ended up in 2nd. New OS Giken diff feels great.

fryzia23 08-30-2015 09:38 PM
Brandan, that Z looks very familiar haha thanks for the pics! :tup:

PharmDZ, the car felt good just the tires have not much left in them anymore. There were 115 entries with 35 pro drivers. Ended up 34th overall raw time 2nd in my class. Next event is on the 12th which is Saturday, you should come up if you can.
