So here's my question,

Why does everyone go with the 9.5/10.5 +15 setup as opposed to an 8.5 +30 /9.5 +15 setup?

Reason I ask is I need wheels, and have been doing research, and it seems like the 9.5/10.5 setup is more popular, obviously its more aggressive, would I have to roll my fenders, and could I use the tires I have currently?

245/40R18 Fronts
275/40R18 Rears

I am lowered on Tein Springs, its not that big of a drop.

Any help would be greatly appreciated.

IMO,
1. the offset on the 8.5 wheel at +30 is weak
2. most people, when buying after market wheels, usually go with a more aggressive size, especially for this type of car.

I have 8.5-9.5 19", but the offsets are only 20-25, respectively. A 30 offset on a 8.5 wheel is WAY too much.

They discontinued the 10.5 wheel in the style i really wanted, so i settled for 9.5 in the rear and 8.5 fr instead of 9.5 all around, to keep the staggered look.

If i had the option in these wheels to do so, i would have gotten 9.5 FR and 10.5 Rr.

You should go with that option if a 30 offset is all they offer on the 8.5. You will be not happy with them if you do.

Will my tires fit the 9.5 and 10.5?

And is there an actual 9.5F and 9.5R? Reason I ask I have a deal with Tirerack through my work so I can get a decent price on whatever they have.

Yes, your tires will fit a 9.5 front and 10.5 rear.

Yes, I've seen members with 9.5's F & R.

why not go with 9.5 +15 all around and get a different tire size? Im going with 245/40/18 and 275/40/18 on 9.5.

I second the question:
would I have to roll my fenders?

My ZR is bone stock & I've been trying to find the right set of 18" Enkei.
Not planning to drop or roll fenders.
But tires I would get brand new set (keep OEM + tires as spares)

Yes you will need a roll with either rear wheels, the 9.5 or the 10.5

Bringing this back...so you would need to roll the rear fenders on a 9.5+15 even with a mild drop (Tein S-Techs)? What if you were running 265/40 or 275/35?

Don't know about the 265/40's, never tried or seen someone run them, then running front tires on the back of a Z just looks silly. My friends car with stock suspension with the RPF1's on the back rubbed slightly with Nitto 555's and Invo's in 275/40-18.

Just run the 10.5's out back, they look great. You will need a slight to full roll depending on the tire (falken 452's run really narrow, Envo's run wide) the the 245's up front on 9.5's will clear no problem.

I was thinking of going with the ENKEI RPF 1s

front:18x9.5 et 15
Rear 18x10.5 et 15

Front tire=255/35/18
Rear tire= 285/35/18

No Drop as of yet....thinking of going with coilovers and a super mild "sport" drop later on. I'm guessing I would have to Roll fenders?

Yes, you'll have to roll the rears. I run 285/35 +22 on the rear and initially didn't have any rubbing problems. Once I replaced the rear tires, the second set must have run a little bit wider and I started rubbing. Since +15 would stick out even more, you'll definitely need to roll the rears.

blitz2k1

You think it would still rub even though i'm at stock height?
I guess I'll stick to the 255/40/18 Front & 275/40/18 Rear Setup, I dont want to be rolling fenders.

some of these comments are misleading

I have read where people have used 275/35 tires on rpf1 +15's without having to roll fenders.

Contact -------> Zippy_z

He is dropped on sportlines (very aggressive drop) and didn't have to roll his fenders, so I don't know what some of you guys are talking about..

Run a 265/35 up front at minimum for the 285 rear tire , unless you want your car to handle worse that stock. Not to mention look sill with a really short tire.

I'm at stock height, so yes, I think it will rub.

blitz2k1 asked about 285, not 275. That's almost 1/2" wider.

a lot of these comments are dead wrong, with a 275 tires, front and or rear you do not have to roll your fenders.... anything wider than a 275 on the rear and you do...

OP - My RPF1s 18x9.5/10.5+15 are on the way. I'm putting the same size tires on and I'm lowered on S-Techs. I'll let you know how it goes.
