When chasing wide wheel widths, you have to put function over form. Find out what fits and only then choose a wheel mfr or model from among the choices that fit.

Start by searching for wheels that do not need any spacer to clear the Brembos. Usually the clearance issue is the back side of the spokes not clearing the faces of the calipers, though for some wheels there is taper in the barrel that fouls the outer "diameter" of the calipers. So that's two more things to check (in addition to strut and fender clearances).

^ i get that. i'm looking more for who has and what can i do to modify front fenders and can i modify them to fit a 275/35 tire functionally. i have heard of people putting washers on the fenders so they are pushed out further. and of course rolling and pulling. am i missing something?, i just cant find anyone running that setup that has discussed what was done up front.

This is near exactly what i am hoping to run, however i expect to not be as low with autocrossing. see how the front fenders poke out at the body line? this is what i'm wondering how to go about doing.

on the tarmac this will be similar to a stock setup for an sti, with a hair more aggressive offset. you shouldnt have any issues running this. with those fenders you can go signifigantly wider on both wheels and tires.

for rally people typically use suspension to lift the cars, and a narrower tire. i cant speak much to that.

I've got serious doubts . . . here's how what you're proposing compares to OE (well over 2" further out on the outside, with about 30 mm of unused space on the inboard side that could be used to cut the amount of poke down to something that might work).

i doubt so with that offset. that would poke quite a bit. i did have a friend who ran 18x9.5+35 with 275/35 tires on his 2016 sti. although he did have coils and i think he rolled his fenders too. i dont believe they were pulled but i'm not sure about that

Awesome, I appreciate the feedback. I'm already addressing arms and whatnot cause unsprung weight was my concern with also going out more on offset, but I'm unsure just how much I could actually go with fenders this wide.

with a wrc style widebody i believe you could fit an 18x10.5 and run like a 295 tire. but double check that and dont take my word on it. i'd have to double check myself to be sure.

I have been searching around and hopefully someone can help out. I am looking at a set of 17 inch Enkei PF01's on a 2017 Base WRX. I want it to be a as close to the stock 17 inch wheel size so I can keep the stock tire size of 235/45r17. Would the 45 inset on an 8 inch wheel fit without rubbing? Thank you .

I thought it would be flush, but it looks like it pokes slightly in the rear.
Not rubbing yet, but kind of worried that it will.

Default 225/65R17 Winter set up on Bugeye?

Iím wondering if a 225/65R17 setup would work on a stock height bugeye.

I was about to install whiteline springs and KYB struts, but didnít know if it would fit under that too. So I can keep it stock height or if they will fit the lowered set up Iíd like to do that.

Can anyone confirm fitment?

I think rubbing at all creates such a poor driving experience that it's worth it to get the rears rolled if you're looking for a flush look. 18s on a GD will create more potential to rub than 17s overall, more so that on GR+ models, so putting GR wheels on a GD will create an incentive to roll, while although not necessarily making it a necessity.


But yeah, I ran 18x8.5s on my Bugeye wagon for about 8 months, and it was lame. Not that you're asking for my opinion on what wheels you should get at all, but 17s are easier to get to fit and are more fun to drive with. Anyhow, good luck!
What tire size? offset? fender mods? camber? asking cause i have 18x8.5 +45 for a 04 wrx wagon and i wanna know how much tire i can fit and what i have to do to minimize rubbing. thank you

Default 2006 Legacy Wagon 2.5i

Hi Guys

Noob here... tried to search first! But didn't turn up a result.

2006 Legacy Wagon 2.5i, dead stock suspension/ride height. Have some very crappy 205/50/17's on it now, and they are terrible in even light snow.

Found a great deal on the more common size, Continental DWS which are 215/50/17. Will these fit on the stock 17" wheels, and suspension?

I've measured with my hand, and seems like lots of space in the rear - front I can easily get my hand in from the tire to strut, I can't see any issue with going 10mm wider, and concerns with the slight height difference? From what I can tell my existing tire diameter measure just a hare over 25" but the setup with the Conti's will be 25.5". This tire doesn't show up as an alternate size option (215/45/17 is) but I know that if anybody knows what fits its you guys.

Thanks!

Hi,

If you have a 2015-2019 WRX or STI, you can try this wheel calculator :

Do you know if it adjusts tire section width as wheel width is varied?

Be nice if you could at least get a demo view . . .

I think last time I posted I was on Tein Basics. Now I'm on RCE T0. Wheels are Gram Lights 57DR 18x9.5 +38, 255 35 Firestone Firehawk. Other suspension mods: whiteline sways and lateral links.

Yes, it ajusts the section width because it is a percentage of the tire width. The calculator is very well made, but I could try to get a demo view.

First off, I have to appreciate the amount of work it must have taken to work up anything at all with clearances. Can't even imagine doing something like that at this stage (I'm retired).


Just to make sure we're talking about the same thing . . . does it include about a 40% of rim width change as rim width varies from "measuring width"? Both sidewall shape and clearances are affected.

I'm using curve fits for the upper and lower sidewalls.
