Would i need fender modification for 18x8.5 +25? with some lowering?

^nope.

Dozer's rear wheels are the same spec's. as long as you don't push over 245's

more than likely with the correct tire. At the most, possibly a slight roll depending on the spring rate of your suspension

i have 245/40zr18 rite now, and i'm gonna put some coilovers later, probably hks hipermax rs, tein basic or megans

I'm looking at some MB Weapon wheels, 18x8 +30 offset, stock size tires 225/45, My car is dropped on Sprint Springs, 2" drop, I currently have no rubbing issues with stock wheels and tire size. Will it fit?

^yes

if i have coilovers then i won't need camber kits for camber adjustment right? would the camber plate on the coilover do the work?

front: 255/35/18 18x8.5 +35 :dunno:
rear: 265/35/18 18x9.5 +35

Bone stock suspension. Will these fit or rub? Thanks alot!

^Stock suspension you should be fine, might run on bumps. What wheels are you looking at?

xxr 006 black w/ chrome lip. i already have a fresh set of pirelli p zeros i pulled off my last car before i sold it(saleen s281). just wandering bc they are amazing tires and would hate to just have them sit around if i can fit them on my 8 with stock suspension ha.

thanks for the help!

I know in drag racing we put skinny runners up front and fat bastards out back. I was wondering for road course or, god forbid cone dodging, would a staggered wheel size from front to back still be acceptable just no runners obviously? Or is it more usual to see 4 matched wheel and tire sizes? Guess I should try to find semi pro race specs but figures I would start here. I would love a set of 18x10s on 295/30s or something and just 18x8.5 up front with what I have now 265/45s.

^Most people around here keep the same sizes all around so it does not upset the 50/50 weight distribution. Cars like the #70 SpeedSource car do run staggered setups...But that's not even an rx8 anymore, so you can't compair.

using two different, but almost similar wheel/tire sizes like this isn't very smart put 18 x 9.5 +40 or higher with 265s on all four corners or 18 x 8.5 +35 and 255s on all four corners

Just so you guys know.... 18x9.5 with a 255/40/18 on a tein s-tech drop rubs bad. i'm talkin camber and roll bad..... so much for this thread haha

What offset are you running?

Sorry, but this post is useless without an offset number. I run 18x9.5 +45 with 275's all around, and I am dropped lower then S Techs, no rubbing what so ever...

well like i said i pulled these fresh tires (maybe 300 miles) off my last car before i got the 8 and would like to use them. i do not auto x or anything like that. just daily driving with a little "fun" here and there. i think i'll be ok as long as i dont rub.

thanks for the input

hey man - i've gotten quite a bit of input from atilla, but just caught this post of yours so thought i'd ask...18x9.5 but +30 with tein s drop...should i go 265 or 275? rolling fender or not...in your experience what's the "coverage" (sidewall) like with 275s on a 9.5? nuke is running 265's i think and said there wasn't too much wheel-edge protection so i'm leaning 275s...

i run 265s on 8.5 and they fit perfect with no rubbing im not sure of the offset though

Just ordered some Stern ST-1 19x8.5 +38. I decided not to go staggered. I know they are heavy... anyway ...
I am being told by same place I shouldnt go any bigger than 235's.
I have stock suspension (cant drop because driveway already scraps if not REALLY careful).
I don't want to rub of course as I put at least 60 miles a day commuting on her.
Is that as big as I should go? Or does it depend on the tire?

^YOu can get 255 all around and be fine, and if you get a 9"+ rim you can get 265 all around

price being a consideration I was thinking maybe 245/40-19's as there seems to be a lot of choices in that size.
What are opinions of the falken fk-452s? Since I put a lot of miles on her... tires will go fast so cheap is good.

Even with a 265 you will run in the front without a roll and some negative camber.

I'm sorry guys they are +35 offset. I rolled the fenders and cut some of the plastic out and it rides fine now.

18" x 9" ET30

Using 245/40/18 tyres

First of all, would the alloys fit the car, and secondly would the tyres be wide enough?

Cheers
