Its finally time for a new wheel size and setup for the E30.

Mystikal, I need some help.

91 318is, 5 lug, coilovered on E38 style 5's.

I will be rolling, and potentially flaring the fenders a bit.

Are 225/45's doable? How about 235/45's?

The more rubber the better, as the car has the potential to have the S52 resupercharged in the near future.

Thanks!

E36 5-lug? Not a chance, the wheels will be flush with the fenders. 205/45 is your limit.

Yes, E36 5 lug.

Extensive flaring, and raising the car a little bit help at all?

It's a fruitless exercise as there aren't any worthwhile 225 or larger 16" street tires that fit an E30. The 215/45 Kumho XS is the best choice.

If you're talking R-comps, yes, going crazy with a fender roller will make it work.

Thinking of using my refinished BBS RA's on my 318i. These are 15x6 ET33 wheels so I am thinking that I'll need spacers to fill out the fenders. Hubs on the wheels are thick so I'll need to determine proper length of ball-type lug bolts - standard bolts w/o spacers are 12x1.50 with a 39mm shank.

Would be running 205-50-15 tires so 6-in. wide rim should be okay. I'm thinking 15-20mm spacers should do it.

Thoughts...would these look good on a d-schwartz E30?

Hi,
I am planning on purchasing a set of MB Seven X's ET38 with slicks 26.0x8.5x15 to use as drag set up. I believe they are Honda fitment, will these work on the back of the E30? What size spacer and certric ring will I need?

Thanks!

I'd go with 15F/20R. For bolts I'd say 50mm for the 15mm and 55mm for the 20mm spacers, respectively. When in doubt order longer because you can always cut/grind/shorten a bolt.

I don't have any experience with slicks, sorry. For the rings you'll need to research based on your wheel model or measure carefully.

[rneedham1979]

Thanks. How about the 15x7 ET38 wheel? 15-20mm spacer?

For slicks, maybe not. The absolute center position for a 15x7 is probably around +30 final offset. I assume you want that for maximum sidewall space for the wrinkling. I'd go with no spacers first and add as needed.

[rneedham1979]

Gotcha, thanks!

Just yell at me if I'm doing it wrong. I got some wheels for essentially free that I'd like to run, but want to know if the required spacing equipment is worth my time/money.

Car: '91 318is coupe, stock hubs, mildly rolled fenders.
Suspension: Very low, not-very-stiff springs. They're green and I can't make out the first word of the name on them, but the 2nd is 'Racing'.

What I'm running now: 15x7 no-names, +25, with 205-55-15's. no rub.
What I want to run: 17x7 rotas, +38, with 205-45-17's.

As far as spacers, I was thinking 25mm in the rear, 20mm in the front, with appropriate studs/bolts and built-in hub extenders. Is this sane? I wanted to move the wheels a bit more outwards in the wheel wells that what I currently have.

Thanks.

LOL, nice. Your 20/25 idea is good.

I have 205/40/16s wrapped on Borbet type E's. The Borbets are 16'' x 7.5, et 35.

I need to rune some hubcentric rings, and it seems like I will need to run some spacers (seems to be rubbing/cuttin it close on the inside of the wheel to the strut assembly).

I have JOM coils coming in soon. I basically want to poke out about the same as the red e30 coupe, or the last picture posted in MightyWhiteys first page.

I will be pming him about his offset if I can find his username. But from what I read, you want anything 20 ish and lower. This will be on my daily, so I do not want to compensate too much turning (I have no problem rolling fenders) and do not want to completely anniliate my wheel bearings.

Just looking for the boarder of safety and looks. What would you guys recommend running?

Thanks. Now time to hunt down the crap I need.

It wasn't that long ago I played the fitment game with my IS300. I got a lot of crap for putting 16x8's on it and had to trial-and-error the tire and spacer fit. Guys like you and threads like this make for a much, much easier starting point.:up:

87 325is sport springs and shocks, IX weaves, 205/55? or 195/55. I can't decide between 195s or 205s, what are your suggestions? i did the little washer and stud trick, and i figured out i need at least a 15mm spacers?
