Question about rubbing

'90 325is billy sports and H&r sport springs
17x7.5 kopis et20

If i add 8mm spacers so this setup, will there by any rubbing issues or other issues?

[Mystikal]

Alright it's mine turn to ask a question. There are 56 pages and I tried searching through this thread but there is a lot of reading.

I want:
15x8 with an ET0

That means I have to run a 195/50/15 tire and roll the shit out of my rear fenders correct?

And our center bore is 57.1mm correct? Is the offset in mm? Thanks.

I am looking at some Diamond Racing Wheels for the E30 right now.

Thanks in advance!

You're correct on all counts, although I don't think the rear rolling will be as bad as you worded it. The tires are so short that I think it'll be okay with just a minor roll, even if the car is slammed.

Yes, there will be rubbing. Especially if you're running the common 215/40/17 tires on that setup.

Thanks for the quick reply Jay,

I forgot to mention my tires in the setup. And you're correct, I've got Falken 512's in 215/40. No spacers for me.

[BMWE34M5]

You should be fine with no spacers - you also may want to consider 205/40/17's instead.
With 215/40/17's all you'll have to do is roll your fenders.
You may experience some minor rubbing with a full load.
90% of our customers go with 215's and their cars are lowered as well with no issues.

Currently I'm running 215/40's without rubbing but i was asking Jay if adding 8mm spacers would introduce rubbing issues. The reason I would add teh spacers is purely for aesthetics.

[BMWE34M5]

Oh, OK.
With the 8mm spacers, you'll have to do some fender work.

how hard would it be to fit these:
17x8.5 et 13
17x10 et 20
215/40/r17
245/35/r17

early arch e30

Would there be any rubbing or rolling of fenders with 16x7.5 et25 225/45/16. I have a late model with ground controls.

[BrewCity11]

Ok, the wheels are 15x6.5. The offset is +38. From reading all your replies, looks like i'll need spacers.

How many mm would you recommend?
Are wheel studs necessary?
And tires? 195/55/15 ?

Susp is H&R race and Bilstein

Thanks alot!

[Kilawin]

Got some new rims again. BBS RS 16x8 et20 and 16x9 et24. Going on my E30 with 5lug conversion (E30 M3 parts). Need tire and size suggestion. Daily driver looking for something smooth and quiet. Thanks

[flawdaboi407]

Wheels are 15x7. Offset is ET35.
Current tires are 195/60/15.
Rear is fine, front rubs slightly on the strut housing.
I have 31mm spacers in the rear.
I want to run 20mm spacers in the front.
What size tire do I need to clear everything ok?
I was thinking 225/50's or 205/50's or 205/55's.
What size do you guys think I should run?
Im going to be getting Falken 912's.
btw.. im on h&r race and billy sports.
Thanks.

A slight fender flare in the rear most likely. The fronts will likely squeeze by with just a flat roll.

ZiMMie's car is running that rear setup with 225/35/17 tires and 8mm spacers. It's CLOSE with flat fender lips, but his ~650lb/in GC springs help there too. Your setup has taller rear tires, which make things a lot more difficult; his setup would not work with 24" diameter tires.

No rubbing or rolling. Very close, but it should be fine, especially with the stiff linear springs. I actually ran a 16x7 ET25 225/45/16 on my personal E30 without rolling the fenders, never touched. There was easily enough room for the extra 0.5".
