Maihem if you want 245s then go with 9.5 +22 all around. 245/40 and not 245/45. Roll and trim the fenders

Also, tire suggestions? stock suspension atm...just getting fitment ideas for future reference.

^This. Stock suspension + aggressive wheels =

255/35/18 will fit nice with fenders rolled.

I'm not gonna have money to get them anytime soon, but I would love to do them with a nice drop, just trying to get an idea for future reference.

Main reason I posted that is the person before you posted a setup that was 3mm different. Math is not hard on that one.

I didn't realize you had...I had just skipped straight to the end seeing as how 233 pages is ALOTTA reading, lol.

19x10 +25 wrapped with 235/40
All the way around.
Will it fit ??

245/35/19 would be a much better tire, and that will fit with rolled fenders, a shaved rear bumper tab, and coilovers.

Javon

Thank you sir

As you can probably tell I'm going for the aggressive look

I figured that is what you did and that is why I laughed instead of helping. They have a search button for a reason. If you have a wheel fitment question, it (or something within a couple mm) has likely been answered 10 times.

I had a feeling that was the case, I never really understood wheel fitment and the math behind it.

Sorry, this is kinda late, but 'better late than never, never late is better"

As before, I mentioned I was interested in 18 x 9.0 +36 on 245/40/18

I have looked through so many pics, and even PM'ed topgear, and seen pics on EUG's car which is 18 x 9.0 +35 on 245/40/18. He is lowered on MS shocks/springs.

Since there are hardly anyone here with Bilstein B8 + Eibach prokit, you guys giving the advice might not be familiar with the drop that it has. here are photos at various angles.
I would say I have no wheel gap, in some of the pics you see me putting 2 or 3 fingers in there, but that is from a very steep angle representing the amount of room I have for offset.

Wheel gap would be the space that is perpendicular to the car's side, which there isn't much from the pics. Lots of you say I will be fine with 18 x 9.0 + 36 with no wheel rub. But what about when I start cornering and turning the front tires?

I am sorry if I sound long winded, I just want to make absolutely sure that it will fit because I can't refund $2000 of rims.

Take a look at my pics below. It's 18 x 7.5 +42

It won't rub on the fenders but it might rub on the fender liner because of the tire sidewall.

It will improve positive scrub radius.

J8635621

iTrader: (10)

Just curious, but do your tires rub on the fender liner now? Mine don't and I'm lower offset than that. I think 245/40 is more than safe. 245/40 on 9 +30 has been shown multiple times to be safe even without a fender roll and does not rub on the liner. +36 should be fine.

Footman - Thanks for the plethora of pictures though. Your worry is unwarranted however. (If I were to drop $2k on wheels I would go more aggressive!)

J8635621

iTrader: (10)

It will increase positive scrub radius. I agree.
Is positive scrub radius a good thing though? I thought it was bad to have a higher scrub radius. That was my point. I don't pretend to understand suspension geometry very well.

Footman

My fenders and fender liners do not rub now. How low is your car though? If I was stock then I wouldn't worry, my main concern is that I am lowered quite a bit as judging from the photos you can see.

J8635621

iTrader: (10)

I'm lowered the same as you or close. I was asking Ross. Sorry

Ross_Dawg

iTrader: (2)

Yeah, my front pass liner rubs on normal driving, I need to shave it down a bit. On hard cornering both liners up front will rub just a little, but not enough to fix. Rear is fine.

fastlaneracing

I wasent trying to sound like an wiseguy either, I have only started to understand suspension geometry myself. ;-)

Positive scrub radius will give better feedback and turn in in general but im not really sure if this is absolutely true for the RX-8.

Lower the ET in general will make a cars behavior from safe and steady (numb feeling) towards more feedback and more informative.

Havent been playing with ET on the rx-8 so I really dont know for sure how it reacts, my racing wheels are ET 45 so thats close to stock.

Ok that's good to know then.

Footman

iTrader: (2)

So 18 x 9.0 +30, 245/40 rubs on the inner fender liner in the FRONT. Is this correct? and I assume you are lowered? I am leaning towards 8.5 instead now

J8635621

iTrader: (10)

No no no. He is 9 +25 with 245s and lower than you. Don't worry about it. What we told you before WILL be fine.

Ross_Dawg

iTrader: (2)

I never said that? 19x9 +25 with 245/35/19 rubs a bit in the front when lowered much more than you are currrently.

I dont know how many ways we can say it will fit with no rubbing.
