I am looking to getting new wheels for my car and was thinking of going with a 18x9.5 +38 with a 12mm spacer up front possibly, and a 245/35/18 tire. For the rears I was planning on going with a 18x9.5 +22 no spacer and a 275/35/18 tire. I am on Bc BR series coilovers and I still have my fender liners all the way around the car. My front fenders are barely rolled and I would like to keep my fender liners. Would this setup work for what I want or should I go with something less aggressive and if so what does everyone recommend.

 

There's a good Excel Sheet on the forums that's helpful for finding your fitment.
Those are some aggressive specs. For reference, I have 18x9.5 +38 with no spacer on the rear of the car, and I feel like the slight pull from my 265's are the only thing keeping it from hitting my un-rolled fender.

Uhh, ok it doesn't look as aggressive on camera as it feels to me in person.

If you're determined on 18x9.5 all around then the spreadsheet seems to say +50 front and +38 rear are the happy spots for getting close to the fender without needing to roll.

 

I wouldnt say that I am determined to have that setup but i am looking at kansei wheels and that I someone else run but never found out what he had to do if anything to get that particular setup to fit. In the end I am looking for the most aggressive looking setup as possible without having to roll my fenders anymore than they already are or take out my fender liners. I would even be happy with an 18x8.5 if need be.

I think the rears are set then because the 18x9.5 +38 is what I was planning on already

What do you think about a 18x9 +12. I know that might be pretty aggressive but I'm not totally sure.

 

Or even an 18x9 would work too

 

Anything under a 40 series sidewall and you'd better seriously watch out for pot holes if you drive on the street. Don't ask me how I know. Also, a squared set up will allow you to rotate your tires, which, for me anyway, might save you some money/hassle in the long run. If you want 9.5's, around +40 offset will work. I run 17x10 +45 with 255/40s with a slight roll in the front like you have and don't rub, even flying down the Rainey Curve.

The old rule of thumb when buying wheels: Cheap, Light, Strong. Pick two.
Unless your heart is set on the Kanseis, a used set of legit JDM wheels (Volk, Work, Advan, etc) might be a good call.

 

I could definitely run a 40 sidewall I would just have to raise the coils but i'm thinking this now 18X8.5 | 5X114.3 | 35 | K11S-188512+35 in the front, and a 18X9.5 | 5X114.3 | 22 | K11S-189512+22 in the rear.
Im pretty set on a staggered setup for the added stability, for the front tires i could run a 245/40/18 in the front, im more worried about the wheel fitment in the front though since I have my fender liners still.
