Non-staggered anyone?
 

Is anyone considering not going staggered? If so what size wheels and tires would you run?

Acura LMP1, Size = BIG :tup:

I am planning on going a lot less staggered than stock. I am gonna put 265/35/19 tires up front and keep using 275/35/19 in the rear. Both going to be extreme performance summer tires, Bridgestone RE-11's up front and Nitto NT-05's in the rear.

I wont be doing this until the stock tires go bald so by the time that happens there could be more options in the sizes I want, but this is my plan so far.

That being said, if I was to run a non staggered setup on this car, I would run 19x10 wheels at all 4 corners with 275/35/19 tires at all 4 corners.

It looks like you could run factory 19x10's with 275.35.19's on all four corners by using a 15mm spacer with longer studs on the fronts.

Just a little bit more traction, running non-staggered, I like that idea.

If you track the car with a non stagger you get the added benefit of rotating tires front to rear.

what does non staggered mean?

same size rims and tires all around? so that can be rotating?

oh i see.

I remember reading an article about a 350Z in '03 or '04 that was attempting to build the best handling Z using a ground up approach. I think they managed to cram 295s on all four corners. They claimed it gave the car unrivaled balance (and as someone said already, rotatable tires).

Alan, check out this pic I took this weekend ;)

I think you will appreciate it hehe

On topic:

Its definitely an option, but there are things to take into account......and the Acura didnt do that great either hahaha

I think they do the staggered setup mostly to keep the inexperienced drivers out of trouble, i.e. build in understeer. My preference would be for a square setup of 275/35 all around, it will make the car feel a little looser and a little more balanced especially given the extra weight over the front wheels. I'm going to be mounting up some Bridgestone RE-11's later this week so we'll see how that goes. 275's should fit on the the stock 9" fronts just fine (hopefully).

That's not the reason why, although it does result in less grip up front and understeer in most cases.

Let me borrow from Kalmairn at 6MT.net:

Quote:

Generally, larger rear tires are used on RWD cars that have significant power output. It's used to balance the power to the dynamics of the suspension/frame. To a limited extent it improves the braking performance in the rear of the car. As with all vehicles, the majority of braking is from the front but the added grip in the rear will help. Speaking for the G35... The larger rear tires allows better application of power and keeps the rear end behind the front end when accelerating in a corner. The G35 Coupe was designed to have a staggered tire layout, changing it to be the same all-around will have a profound impact on the handling characteristics of the car. If you upsize the front to match the rears you'll find the car to be less responsive up to the limit; at the limit the car will likely let go much quicker than it would in stock form. If you downsize the rear to match the front you'll find acceleration traction reduced, the car will rotate easier and at lower suspension loads. As with any performance RWD car, it's best to maintain the stagger. Kal.

True, I agree 100%. But in every day driving(speed limit), would those rules still apply?

I meant understeer, not oversteer.

Nothing that involves losing grip relates to everyday normal driving. Unless its snowing, dont worry about losing traction if you are going the speed limit.

RE-11's do not come in a 275/35/19. Are you planning to mount the 275/30/19's? If so, they are much smaller diameter than stock.

IIRC, be careful about your tire size choice with speedo accuracy being one thing. VDC gets flakey if the width difference between the front and rear tire is not within nominal range.

RFC

Good one. I think Acura may be scratching more than their heads after Sebring.

Funny thing is that RFC are my initials...

The rears will be slightly smaller than stock as well. In revolutions per mile the difference between front and rear is 11, with the tires I chose it will be 9, so within range of normal differential. They are primarily going to be used at autocross and track where VDC will be turned off anyway so if it becomes a problem I will mount up the stock tires on some new rims.

Does anyone know if the speedometer takes its reading from the front or rear axle? Wheel speed on the rear will be 1% faster, wheel speed on the front will be about 3% faster. Differential front to rear will be 1.1% overall which is less than the 1.4% of stock, I'll just have to watch out for potential speedometer error.

Which brings us to..."How much speedometer error is there from the factory in a stock 370Z?"

Yeah I'm waiting to find one of those digital speed readouts that the police put out. They usually have one or 2 around town except for the winter.

Mine is actually very accurate. With in 1 mph.

My STi always said I was going much faster than I really was.

Higher or lower?

Got my Bridgestone RE-11's mounted up today, they are super sticky for a "street" tire. They're not even scuffed in yet and I already have more grip than the RE050A's.

Given that the sizes available in 19's are very limited I had to actually go a little larger than would have been normal. 305/30 rear and 275/35 front, they actually fit better than I was expecting. I pulled the camera out to snap some pics but the battery died :(

They have a very stiff outer sidewall and a slightly softer inner sidewall, corner feel is excellent. Haven't taken it to the cornering limit yet as they are too new and a little greasy. Will have more info after a weekend of Auto-X in a week.

Mine looked like it read 1mph lower than the radar sign.

Actually I tested it again yesterday and it was dead even with the radar sign.

Charge-up that camera battery, snap some shots and post please.... I'm really interested to see how well (or otherwise) they tuck under the fender-wells.

Thanks!

Here's some:
Mounted RE-11's

I'll get some outside shots here when it stops raining. As you can see there is plenty of room, but you would be better off with a 10.5 or 11" rim in back.
