What about 16x8 et 20, stock 4 lug set up.

225/45R16?

@ Staszek. That is the perfect wheel set up for E30 in my opinion. I have been running it for years. The only questions would be tire brand name. 224/45/16 Nexen may not rub up front, whereas 225/45/16 Goodyear may rub. Each manufacturer has their own specs.

Sounds crazy but good luck. Cheers!

I asked this question earlier, but just stumbled on some new wheels for cheap.

1989 325is

Suspension
Ground Control Street kit Coilovers
Nasieg 5-lug conversion
Front
e36 M3 front hub (Pushes out +12mm)
Rear
z4 Hubs (Pushes out +2.5mm)
Wheels
e39 Fitment Style 32s
Front - 17x8 et20
Rear - 17x9 et26

I have hubcentric 10mm, 5mm, and 3mm spacers on hand and can do a roll as well.

What tire sizes am I looking at?

Thanks!

The front strut is still e30. Not running anything e36 besides the hubs. It's effective like running a 12mm spacer. That's why I chose 17x8.5 et20.

The 3mm spacer on the 16s is for caliper clearance, the apex won't need that

For tires I chose
215/45 front hankook rs3
225/45 rear hankook rs3

Will report back how they fit

You're still going the wrong direction. 12mm spacer means you should be running 12mm higher offset, not lower.

And the tires are all way too tall.

Ok these are the 7's which is slightly better but probably still not good enough from what you are saying.

They're actually even worse then, with the +20 offset vs +23.

E36 5-lug, 225/35/18 tires would be perfect.

Only with a rear fender roll.

Stretched tires and no spacers. 205/40 front 215/40 rear AND a rear fender roll. They will sit flush.

Thx for the input.
Front has a ~5mm gap between strut, so the offset is just right for front with the 5x120 sleeves. The tires are pretty tall but they just barely fit in the front.

Ok sounds good I was planning on rolling the rears anyway so they would fit fine with that.

[Daeldalus]

17x7.5 et38

how much spacer would i need?

could I run a 235/40r17 tire all the way around?

Sure, get 12mm spacers for all 4 corners. Fits with a rear roll.

Thanks I am looking at

DIREZZA ZII STAR SPEC they have the same section width as the Nexen at 8.9"

So hopefully that would work!

Jay,
Any thoughts on how I could fit BBS RM's on my '92 vert? I know stock on the wheels is 15x6.5 et 33.
I'm looking at a set that 8" wide with bigger lips. I'd want to have 3" lips on the rear. Would that work?
Suspension is GC conversion kit.

Thanks
