Widest wheels you can run on a stock S2000

[EP3TYPER]

Hey guys, as topic states I just want to how wide you can go on an S2000 (stock height and stock suspension) without having any scrubbing. I currently have 17x9+45 on the rear and 17x8+35 on the front.
I am happy with the rears but the fronts stick out about an inch and cause stones to flick up and hit the lower part of the door. I pretty much just want to have them in line with the guards to avoid that, if that makes sense?

Thanks.

any camber?

[EP3TYPER]

Nope car is stock as a rock

[charlie15]

You have 17x9 +47 and 17x8 +33

[curtis265]

actually - i use 17x9+63 and have zero scrubbing at stock height

I always ask questions on both forums, sometimes you get nothing good on one and everything on the other.

For those with the same question, found this on S2ki:

For the front:
Offsets lower than +43 are not recommended on the front because a very narrow tire would need to be used to avoid rubbing.
+43 to +47 offset: 205 tires, 6.5" - 7.5" wide wheel
+48 to +52 offset: 215 tires, 7.0" - 8.0" wide wheel
+53 to +57 offset: 225 tires, 7.0" - 8.0" wide wheel
+58 to +62 offset: 235 tires, 7.5" - 8.5" wide wheel
+63 or higher offset: 245 tires, 7.5" - 8.5" wide wheel

For the rear:
Offsets below 40 are not recommended for the rear because a tire narrower than the stock tire would need to be used to avoid rubbing.
+40 to +44 offset: 235 tires, 7.5" - 8.5" wide wheel
+45 to +49 offset: 245 tires, 7.5" - 9.0" wide wheel
+50 to +54 offset: 255 tires, 8.0" - 9.5" wide wheel
+55 to +59 offset: 265 tires, 8.5" - 9.5" wide wheel
+60 to +64 offset: 275 tires, 9.0" - 10.0" wide wheel
+65 or higher offset: 285 tires, 9.0" - 10.0" wide wheel

you would think that with a car that is now 15 years old, someone would have asked already

[EP3TYPER]

Well they did as I was linked to the information, couldn't find it in a search though. Probably noob searching on my behalf

will enkie rpf1 17x8.5 +30 fit on s2000?

No point fitting too wide tires on a stock S2000, you'd be dragging the car down because it doesn't have the power.

That being said, my opinion is that you run 215/245 or 225/255 to keep the staggered layout. If you're running square, and to imitate that staggered layout, you'd need to stiffen up the front a little bit more than the rears.

Opssss didnt see frist page:p

I respectfully disagree. I'd recommend going as wide as possible more so on rim width. A number of local track go-ers are putting down good lap times on quite fat tyre/rim setups... Myself included and I'm pretty close to stock power :)

As for the OP, my recommendation on S2ki to check out Urge Designs still proves to be the best option out of all the ones provided on both boards :p

Do you have aftermarket suspension though ;) and how wide is wide :p

I think instead of explaining.. better to see what US AutoX champions use in stock class cars :) Even then they're going beyond the 225/255 setup you recommended with stock rims :p So if you have a range of aftermarket rims available then... :)

http://www.s2ki.com/s2000/topic/172595-s2000-stock-class-autocross-information/

Didn't realise the OP was going to stay with stock suspension - oops. But still I stand by - wider is better :) A track is made up largely of corners, so the more lateral grip you can maintain throughout - the better, even at the cost of longitudal grip. But all of this may be irrelevant to the OP depending on what he's doing really :p

Yeah but with his suspension setup the staggered would be the way to go, that's what I had in mind when I was recommending sizes to him mate :)

As I had mentioned if he wanted to go non-staggered he would have to fix his suspension to do so, and personally 255 is the max I would go both F/R. But the OP would need to modify his current setup and possibly add a wing or stiffer front sway bars as non-staggered is known to cause a lot of oversteer due to the additional front grip, and to stick to stock setups it would very dangerous for beginner/intermediate drivers as it's way more difficult to adjust for high speed oversteer without sufficient experience.

Ah, I kinda figured that's what you were going for :) But I would still say to go as wide as he can but keep a ratio due to the suspension setup (staggered). Or add a front sway and go non-staggered since a wing will look both silly on stock suspension and attract unwanted attention :D

[EP3TYPER]

Hey guys, thinking of going for 17x9+45 and 17x8+45. I think that will give me a flush fit at stock height. What do you think?

[curtis265]

http://random1photo.zenfolio.com/img/s9/v13/p46981448-4.jpg

not my actual car but here's how mine fit

17x9+63 all round

[EP3TYPER]

I pretty much want to have the wheels flush with the guards, 63 is too high for me.

Nah mate you wouldn't go 285's with stock power :p, 255's are max you would run unless you want to add a turbo or supercharger to it ;)

Curtis's one looks pretty flush to me :o, are you going for the rpf1's by any chance, your width/offset combinations happen to be the max they offer.

You're going to need to roll your guards if you want to run 235/255's or 225/255's with that setup.

-I currently have 17x9+47 on the rear of mine and its flush
-Currently running 245 and 225 and there is no need for guards to be rolled (I am at stock height)

[DreadAngel]

Just tub the car, problem solved...

Ah I assumed the car's slightly lowered. So you'll be running 225/245 I assume?

Because if you're going to run 255's in the rear you would most likely rub. Unless you're running some camber of course, then it might possibly just fit.

[EP3TYPER]

Nah will probably stick to 225 and 245

[aozora]

Nah mate you wouldn't go 285's with stock power :p, 255's are max you would run unless you want to add a turbo or supercharger to it ;)

I would :) Faster times are won in the corners, not the straights. Let's put it down to a difference in understanding...

A lot of factors come into play mate here's an example of how wider tyres caused an increase in lap timing on a stock car.

http://www.roadandtrack.com/special-reports/scion-fr-s-tire-transformation

Now if that FRS had aerodynamic modifications and a whole other things done to it. I would expect a better lap timing with wider tyres.

My point is that your tyre should only be as wide as your setup allows you to, so as to make full use of it.

There's always a trade-off, more isn't always necessarily better.

Especially on a stock s2k.

[dove grey 64]

You can work out what width and offset will get you your desired fitment with a straight edge with level and a tape measure.
There are such things as being overtyred for stock setups, obviously going for a lightweight rim helps to counteract that.
I would personally recommend coilovers first (eg. Shockworks) then rims but each to their own

that article is essentially useless as they changed wheel diameter, tyre size and overall diameter all at the same time.

it even specifically states that some of the speed loss on straights was due to the larger diameter tyres. However the results showed it cornered better. I would much prefer to see the results using the same diameter wheel and same overall diameter.
