You'd be rolling the fenders front and rear, and you still may end up with some contact in the front well while turning sharply. The tires are too tall.

Slightly off-topic... Mystikal can you tell us more about your style 5s? What are the widths, offsets and what tires are you stretching on them?

They look.. awesome.

[Mystikal]

Thanks man.

18x8 ET20 front, 18x9 ET22 rear, with 215/35/18 ZE-912s all around. The wheels were the rare factory option for E38 7s. They do not work with stock rear fenders. We pulled mine pretty aggressively, as the RIM was rubbing the fender.

just got 15x7 and im not sure what kind of tire to get, car will be mostly track and autox but needs to be streetable. any suggestions?

You can go up to 225/50/15, but there's isn't much worthwhile in that size.

I'd either get Nitto NT-01s in 225/45/15 (this leans more towards the track side of the equation, but it's still 100% streetable) or any of the new top-tier street tires (Bridgestone RE-11, Yokohama AD08, Kumho XS, etc etc). Only a select few are available in 15" now, but they are all excellent.

I'm rebuilding a set of BBS RM012s. Original specs are 6.5x15 et33, backspace is 128mm. I'm trying to decide what width to get for the outer lips. I can rebuild them anywhere from 7"-8.5" (possibly more, but I'm not that adventurous). Will a staggered fitment of 205/55R15 front and 225/50R15 rear on 7" front and 8-8.5" rear work without metalwork on stock suspension? Will it work on a modified suspension (mild drop - 1.5" front and 1" back or there abouts)? How pronounced would the understeer be with the staggered setup? The car isn't a track rat - it's an '88 cabrio (wife's car).

For reference: the increased lips will add the following outboard (in mm): 7"-13, 7.5"-26, 8"-38, 8.5"-51. So basically, adding a 2.5" lip to bring total width to 8.5" adds 1" to the outboard. My eyeball says stock suspension can take this, but I don't think the front will take 225 profile.

These are the approx final offsets:
15x6.5 ET33
15x7.0 ET27
15x7.5 ET20
15x8.0 ET14
15x8.5 ET7

Basically, if you want to run a 225/50/15 without rolling the fenders the 15x7 is the absolute maximum. Yes, there is this little room. Also, contrary to popular assumption, the front of an E30 (especially an 88+ car) has significantly more tire clearance than the rear. Yes, strange.

If you want to widen the RMs, you will want to stick to something narrower than a 225. A 15x7 w/205 and 15x7.5 w/215 will work though, if you're committed to running staggered tires.

I answered you over on R3V.

Hey Jay,
This is about my third fitment Q, but w.e.

BBS RA 15", 35mm offset. Tires are 205/50/15 Kumho Ecsta SPT.
I'm not 100% on this but I'm guessing they're 6.5-7.5" wide?

So will those fit without modification? I have H&R springs/Bilstein struts for suspension. Will I need spacers?

They're either 6" or 6.5".

They will be dangerously close to the front struts, and sunken into the fender pretty far. I'd run 15-20mm spacers with those.

What tires i need for these weels if my car(1986 e30) has sport suspension,powerflex rubber,eibach strut bars:and the fenders are rolled?

Front: 18/8,5j-et30
Rear: 18/10j-et20

What do you think 225/40-R18 front and 255/35-R18 on rear will work??

Even with 215/35/18 at an extreme stretch on the rear will require pulled/flares fenders just to have the WHEEL clear it. 255s are absolutely impossible.
