You won't notice.... you're talking a 2-5mm difference from stock

haugi88

Keep us informed on that one I also thinking about this setup and how i can get it to work. But i would go for +15, not +30.

Wow, double good luck.... people understand from my previous posts that these probably wont work and if they do the car is going to handle terribly with constant rubbing right? And you're trying to go even more aggressive.

All that will do is add another 15mm to your fender issues 😉

How about 255/45/17 on 17x9 with 45 mm offset?

Koni's with RB springs (and sways)

I have the wheels on the car now with the tires that I autocrossed my NC on ... 245/40 and they look way too short to my eye ... the 255/40 is not much taller hence my interest in the 255/45. I'd love to have a more aggressive offset like your 35's but I already own these 45's so that's what I'm working with.

10mm spacers would do the same thing...

What about 275/40/17's on the same 17x9 45mm wheels? Clearance issues? RB springs with Koni's

Not sure if this will rub? I do have the Öhlins Road&Track coilover though, so I COULD adjust the ride height myself, but still not sure if it'll rub the fender or the suspension?

^ Do you plan on putting some rubber on those?

Sato Tatsuya

Haha! No, I was planning on making it as light as possible... :P

I was thinking of going either the following:

Option 1: 265/35/18 ( Square Set-up )
Option 2: 275/35/18 ( Square Set-up )

I did think about going staggered, but I prefer square, because then I can rotate the tires, and more out of it. Also, weren't sure if I should stick with '40' for sidewall or not?

Having said all that, I do suspect that there will probably be clearance issue for the front, and not for the rear. However, I was curious whether the clearance issue is something that could be rectified by adjusting the ride height?

Lowered I'd say you'll be able to make the 265's fit. It'll be tight and some mods to wheel well liners might be required to eliminate rubbing. You'll need a fender roll and should be able to stay withing stock spec camber. Those will fit very similar to mine except the inside edge of your tires will sit 10mm closer to inside of car than mine because of the offset difference. Outside edge of tires will sit exactly the same as mine. (I have 255/30's on +30mm offset).

275's up front will require much more work to make them fit without lots of rubbing. It would be more than I'd be willing to go but I don't think it would be impossible with the right suspension adjustments (not sure exactly how much room you have on the inside). Both tire sizes I'd say you won't have too much issues in the rear but will need a fender roll. If you went 275's in rear you'd need slightly (very minor amount) more chamber but again, I don't 100% know how much room you are working with on that inside edge of the tire and clearance of the suspension components (my assumption is more than enough).

Again, disclaimer being I'm no pro, I'm just a guy who did a bunch of calculations to figure out what would work on my car with as little mods as possible but still have that flush/more aggressive/clean look. My recommendation would be fit the 265's and if you find that maybe there is some extra room you think you could work with then next set of tires try the 275's out. That was my logic going with the 255's now, next set of tires in a few years will be 265's and a very minor camber adjustment.

Sato Tatsuya

Thank you very much for your feedback and sharing your experiences! I really appreciate it!

Question: if I was raise the ride height, or even bring it back to stock height, do you think I could get away without cutting the fender liner? I also do not want to make any modifications if I do not have to.

Thanks!

Potentially, I can't say for sure. Is having huge wheel gap really worth the 10mm width 275's will bring over 265's?

Sato Tatsuya

Apologies, I should have clarified! I meant to ask if I was to go with the 265s, you mentioned that I may have to do some modifications to the fender liner at the front of the vehicle to present any rubbing -- I am curious whether I could adjust the height of the vehicle without cutting the fender liner?

Height adjustment (without changing any other suspension geometry) will never solve any problem. All it does is give you more movement before collision occurs, making it less likely to hit (you need to hit a bigger bump before you have a problem). It's a band-aid at best, and I would never suggest using ride height to "fix" interference issues. Solve them correctly by eliminating the interference (fender roll, reshaping wheel well liners, different camber, different offset, different tire, etc.

Remove the spring from your strut and move the wheel up until it goes no more (and turn the wheel side to side in the front) - it shouldn't hit anything. If it does, then you should fix the problem, because it could hit while driving.

Sato Tatsuya

Thank you for that explanation! And it would appear that the tire and wheel will actually fit on my car with less issue than expected. The person I'm buying the wheels from currently has the stick 2016 STi tires, which are 245/40/18, so although I do not prefer stretched look, it isn't too stretched, and it should fit without any rubbing. When I new tires I will then go and make the appropriate modifications to make it fit properly.

Hi,

Currently running 18x9.5 + 30 wrapped in 265/35. Fenders are rolled and bumper tab has been taken care of...

I'm in need of new tires and while the 265/35 isn't in stock the 275/35 is... will there be any big enough difference? Or just force them to order the 265/35?

I currently have zero rubbing issues, and do plan on raising the car up around 0.5inch from where it is as of now.

Thanks.

They will be slightly taller sidewalls and 5mm wider on each side of the rim...... Go look at your car and figure out if you have 5mm of room through your entire turn radius

Going to run 255/40/17, 17x9. Enkei RPF1. Track wheels.

Thanks,

Currently running 18x9 ET43 with 245/40 tyres and tein tein coilovers. I tried 20mm spacers on the back so effectively ET23 and it rubbed a lot...

Just bought some new wheels that are 18x9 et20 can I use my 245 tyres and roll the arches or is that still going to be too much? Can adjust ride height of needed

wiggle5

Oh and that's going to be et20 all round now not just the back

You say 18x9 +23 rub and want to know if 18x9 +20 will rub with the exact same tires?????

Yes, you'll have 3mm MORE interference.

If you're asking if a roll is enough, I'm inclined to say no way (without camber out of stock specs), but maybe someone else knows better.
