just picked up 4 Kopi 17x7.5 20mm Offset wheels from abrahams motorsport and also ordered 4 bridgestone Potenza RE-01R 225/45zr17s.

i want to run them on my 1991 325i vert thats running bilstein BTS sport shocks and springs with a 1.25 drop.
i was told they would only rub on full lock turns but im kinda worried .
i dont mind if they rub only under full lock but thats about it.
they also have them in 215/45zr17s or 205/45zr17 that i may be able 2 exchange them for but im not sure
what do you think?
thanks in advance for the help

I doubt that car will even be able to roll with those tires, let alone traverse a bump. The tires will be crammed into the body.

The 205/45/17 would be the correct overall diameter.

17X8.5 all around running ET0 in the rear and et10 in the front.
If i run 205/40/17's what do u think, i can get away without rollin the fronts?

Hey guys...here I go with wheels... Damn am I frustrated.


So I am looking for some nice wheels, and I have them all picked out. It just comes down to size. I want bigger than 16" wheels, so here are my thoughts...

Work VS-XX
18X9 Rear ET? Also - with the correct offset - what is the lip size?
18X8 Front ET? Same lip size question.
What tires can I run?


Sticking with the 4X100 (so far), 3 piece wheel, and I need to have them custom made. What should I tell them to use for a center bore?

Thank you for all the help in advance!

I'm looking into getting a set of falken rt-615 tires. My wheel specs are 16x7.5 in the front and 16x9 in the rear. Will rt-615's in 215/45 fronts and 225/50 rear fit? If not can you suggest some other tire options that will work with my wheels? Thanks.

Hell no. I'm just putting this answer out for the board to see, as I already smacked you in the head last week for asking me this.

18x9 ET25 rear 225/35/18 tires
18x8 ET30 front 215/35/18 tires
57.1mm centerbore

Rolled rear quarters minimum, might get away with the fronts.

I need your wheel offset.

You're not getting anything bigger than a 215 on the rear without flaring the fender.

215/45/16 RT-615s front and rear will work. Alternatively, 215/45/16 Hankook R-S2 front and 225/45/16 rear with some serious rolling/flaring.

How much stretch will the 215/45/16 have on a 9 inch wide wheel? Also, the 225/50 definitely won't fit even with rolled rear fenders? I am trying to keep the tire-stretch to an absolute minimum. Thanks.

Fine Im Going Wider then.
U'll get a call every time i rub.

BBS 17x8" all round, ET40.

What size tire and spacer, bearing in mind that I'm running E30 M3 hubs and currently sit on an ET30 15" wheel.

Without spacers, I'll have 23mm less room at the strut end and 3mm less room on the lip side.

VERY stretched.

With that offset and wheel width, 225/50 won't fit without a visible flaring of the fender. Think custom bodywork.

Look into 245/35/16 Toyo T1-R. Will be easier to fit. You could put the 225/45/16 or 225/40/16 on the front.

15mm spacers all around, and a 215/40/17 tire will fit fine without any fender rolling. Alternatively, a 235/40/17 (or 245/35/17) with the same spacer will fit with a fender roll in the rear.

Will it be ok with Ground Controls, and will I be able to drop the car to a full drop if I wanted to?
