Thank you to the above posters. Would the lower 40 offset keep things more flush. That's what I'm looking for. Really don't like sunken in wheels and tires. A little rubber poking out is fine with me. No stretch.

I'd think 255/40/17 x 9 +44 would be pretty flush. That's 1mm off of my summers and I run 3mm spacers. You could always add them too when you're not tracking it.

You'll have to see what the wheels you're considering are offered in too.

Hey did you have to get a rear camber kit installed to fit those wheels and tires under the fender?

Thanks again. I'd imagine switching to 18s totally changes the equation. I feel like they fill the fender better but the added cost and weight detours me away from the idea.

It shouldn't change anything if given a tire of the same width and similar total height.

Tire size fills fender, not wheel size.. imo!

No rear camber kit... you get a - degree of camber for every inch you drop...

They don't fill the fender any more than a 17" wheel/tire setup that has the same diameter/radius. A 225/45/17 setup has the same radius/diameter as a 255/35/18 setup. You're just trading sidewall for width and diameter.

I see. Then I guess my question would be: in a performance/ track application would it be better to have the 17s and more sidewall or the 18 and less sidewall. I would like as much width as I can without having to kill my fenders. Again all while keeping a 1inch gap. I don't slam cars.

I'd suggest stick with a 17 inch wheel that's got 255/40/17 tire. It's the same as a 18 with 255/35/18 as far as width and rolling diameter so it'll fit the same on your car.

The 17's will give you more tire sidewall and less wheel, which sounds like less weight to me, but I guess that'll depend on the specific wheel and tire combo.

And since its on the shorter rolling diameter side of what fits on our cars, I'd opt for the setup with more sidewall for better rim protection and ride comfort.

(If you weren't tracking, I'd say go with 18's and a taller setup for looks). My .02

^ Good points. I think it works both ways.

17s: pros
-Good rim protection and comfort = good for daily driving
-Lower unsprung mass due to smaller diameter wheels = good for racing
--Unless the added weight of the larger sidewalled 17" tire negates the weight advantage of the 17" wheel

18s: pros
-Smaller sidewall = stiffer sidewall = better for handling/racing
-18s tend to look better on our cars because they're not exactly small cars

I just prefer 18s. My 18" Rotas weigh less than the stock 17s, my tires aren't stretched, I'm lowered 1-1.25" and I have stock fenders (not rolled or pulled) so I'm happy with my setup. On my last car, I went with 17s and ended up regretting it, but it's totally up to the individual.

SWP, what width and offset and tire combo are you running? If I don't have to modify my fenders at all I'd be stoked. I'll have to research weights and see the difference. More sidewall is definitely more comfortable, but less sidewall will make the tire stiffer and add to handling. Man oh man.

Food for thought...
Some tires don't come in 255/35/18. TireRack on sells 5 different tires in the EPST category at that size.

Switch it to 255/40/17 and you get 9 results.

I'm looking at rs3, the new star specs, 595 rsr, or ecsta sx. The more rubber I can out down the happier I am. Just don't want to have to mangle my fenders.

He's running 18x8.5 +44 grids with 225/40/18... Unless he already switched to the 235/40s he was discussing awhile back... But he was not expecting to rub even with the 235s

Hm. I wonder if going 9in wide is a bad idea. I love wide wheels but 255 will be rubbing I'm pretty sure. I want the grip though!

^ Correct, 18x8.5 +44 Grids on 225/40/18s, lowered 1.2"f/1.0"r and still a safe amount of space between the fenders and the tires. I have 235/40 Federals mounted on the Grids sitting in the garage now, which will go on in late March and I expect no rubbing problems at all, even with stock/non-rolled fenders. There was a good amount of clearance when I had the 225/40s on.

The post above with cutty3zx is exactly what I want. Wide, no fender mods, not dumped, lots of rubber. If he's autoxing with no rub I should be set.

PM him just in case he's not keeping up with this thread. He doesn't look like he's lowered much even though he's on coilovers. The 255/35/18 tire will give you a 3.5" sidewall which is still pretty decent for daily driving. The good thing is, you have coilovers so if you rub, you can play around with the height instead of rolling your fenders.

So, I usually figure out my on fitment questions using online wheel offset calculators and/or other people's setups for reference. I'm stumped on this and no one has answered my question in the wheel fitment thread. So here it goes:

Considering switching up to a different set of wheels. But I have a fitment question...

My current setup:
Year: 2009
Model: WRX 5dr
Wheel Model: Drag DR-31 18x9 +38
Tires: Sumitomo HTR ZIII 245/40/18
Suspension: GTWORX/Bilstein Cup Sport Kit w/ RCE Blacks & RCE Camber Plates (front), Whiteline Rear Camber Adj. Bushings Kit (rear)
Fender Mods: Rear fenders rolled, fronts slightly pulled
Camber: -2.0 front, -2.0 rear



^As you can see these fit fine. I run 3mm spacers. This picture my camber was -1.4 front, -2.5 rear. Since then my camber has been adjusted to -2.0 front, -2.0 rear.

So my question is:
I'm considering switching to WORK XD9 18x10 +38...

How much more will these poke?

18x9 +38 vs. 18x10 +38

Half of an inch is 12.5mm. So that's my guess. But according to http://www.rimsntires.com/specs.jsp, there is no change (given i run the same size tires) Is that right?

So, I'm guessing the wheels will poke 12.5mm more but since the tires will be slightly stretched, the clearance of the tire to fender will be similar. Any opinions?

Tired PMing. No such luck on response yet. Like him, I d. 't plan on lowering much. I just had to get rid of that 4 inch gap between fender and tire haha. I have taken away over half of that and am pretty satisfied with my height. I'm not totally against rolling my fenders if its done right and doesn't destroy my paint. You look at Subaru paint funny and it falls off. hopefully have my CRX sold soon and ill be going to do wheels and tires

I'm guessing here, but I imagine that clearance will be similar where the tread is, but slightly tighter towards the actual wheel...? So it shouldn't make much difference unless you compress the suspension enough to truck the wheel up in there... ?

That size wheel might be getting close to the struts too in your setup..?

This may be too aggressive for you guys.

Oh yeah, 7'' wide OE wheels, +25mm spacer [switching to ~30], 225/45, rolled & slightly pulled.
