hm.. i forgot there was a rule on how thick the spacer could be, i actually thoguht it would help the car plow less. guess my thinking was incorrect? my original intentions were to use it on the street to give the rear more of an aggressive stance, just for looks, but i figured i'd throw them in for auto-x also (spacers aren't on, actually looking to buy them off the classifides).

 

It could help with reducing body roll, but you can also do the same by not having to turn as much.

Remember, Miatas and Minis do pretty well because they are relatively narrow, so they don't have to turn as much, especially in slaloms. Corvettes do pretty well because they have plenty of power plus they have enough tire to get the power to the ground.

However on the street, do what turns your crank! I see a lot of Zs on here that look great!

 

I just want to thank everyone who contributed to this thread!

For a novice like myself the information contained in this thread is very valuable, specially since I know very little about car set up. I'll let you guys know how it goes with the changes I made based on the above posts!

Thanks again for all your contributions!

 

I've made a few changes to the setup I posted. Will be posting more later this year as we test out new options.

 

is 45psi + tire pressure streetable?
I might have to pressure up before going to auto-x and thats about an hour something of drive on high way...

 

I wouldn't run my pressures that high on the street, not for an hours drive.

Look for a gas station near the event, or buy a small dc air compressor to pump up your tires at the event.

 

Very kewl, looking forward to it, and hopefully seeing more Z's at the top of BS results!

I'll be going to the Ft. Myers NT, this is my first big event and I'm sure I will learn a lot. I just got my 275/40/17 V710s mounted this week and have a very short time to get used to them, hopefully at least enough to do decent at the NT. I'll be ok as long as I dont end up dead last, but hey if I do, its all good I'm sure I will learn plenty. Ft. Myers is a great site and should be lots of fun.

Any tips for my transition to R-comps?

 

Smooth driving will make you faster, but the R compounds will hide small mistakes (for a while).

The limits will be significantly higher, and unless you are used to them, you won't get as much out of the car as you will later when you are used to the higher limits.

 

Its been a while since i've crushed cones, but in any of the stock classes, i didn't think you could run different sized wheels (beyond the 10mm offset allowance). doesn't the touring come with 18x7.5 and 18.8 F/R?

ahm

 

All of the Zs prior to 2006 except for the track come with the same size wheels front and rear.

 

this is definately wrong. i have an '03 enthusiast, and oem fitment is 17x7.5 front, 17x8 rear. its cast into the wheel. performance and touring both got 18" wheels during those years, and are, as far as I know, also staggered in width. i'm not sure what the track had - 18x8 f and 18x8.5 rear?

ahm

 

The non-Track (and non-Base) models are 8" front and rear. A small concession for running 18" non-Track... race rubber rotation in stock trim.

Just a note from above, air pressures for A/X'ing are definitely not recommended for anything but "on course" use. Running A/X pressure on the street is dangerous. Air tanks are cheap, less than $30, don't risk running A/X to or from an event.

Hey, what about those poor folks with '06 Zs running 19" wheels? Are Hoosier or Kumho working on a 19" tire?

i think you're responding to me, so if not, sorry. again, this isn't the case. at least if you're talking about the 03's, i know my enthusiast came with 17x7.5 front, and 17x8 rear. here's a shot of the inside of one of the spokes.

ahm

 

Interesting thread, wish I had more to contribute. On that note, here's a must have item for autoxers and tracksters. Cordless handheld air compressor. I just got one for Christmas. It is awesome.

BA, I think you are being too conservative on the camber. -1.5 is within factory spec. I ran it for 16+ track days and 6000 street miles with very even wear in the rear. I wish Nissan would make the front camber adjustable. That would help a great deal. Finding some tires with the most camber built in would be an interesting way to boost camber up front, which is definitely too conservative. I know Avons have a lot of built in camber. Unfortunately, they only come in 17" and limited widths at that. As an aside, I would run the 10mm spacer up front.

I don't know the rules, but could you theoretically run 18x9" instead of the 19x9"?? If you converted everything else required?

 

amolaver,

I guess I could've stated that differently... I was trying to say the 17s and the Track model have different widths front vs. rear. My Touring model has 8" front and rear. Sorry about that.

zillinois,

I think the front camber settings I quoted were all I could get out of my car's stock equipment... yep, it's way too conservative... but like you said, Nissan hasn't provided us with much to work with.

Whoa! Is that handheld air compressor quick to inflate? Looks way cool.

As far as I know, the stock class rules will not allow subbing 18"s for the 19"s. It looks like they be forced to run in BSP with alternate wheel diameters... if they want to run on R-compound tires.

I've broken 2 of those inflators. I would suggest wrapping the hose with tape to strengthen it. The hose usually breaks where it bends the most which is at the tip and the base.

 

I was talking about the rear camber. I'm pretty sure -1.5 is spec and you quoted -1.2. Just a thought, you could add some in the rear. My wear was fine with -1.5 and that was with 295/35's. Are there any Rcomps with camber built in?

I thought it might be possible to go down in size like running a smaller rim that stock might not be contested? I wouldn't want to find 19" rcompounds!

The inflator works pretty good. Looks like it might have a weakness though.

 

Thanks for the tip. I'll definitely figure something out for that. Could probably find an old bike pump around and take the hose off of it and use that maybe.

 

zillinois,

I have 15,000 miles on my current street tires, the rears have a mild amount of inside wear... you're right, I'm making a compromise for extended tire wear.
