Yup, or 205/50.

Lots of nice 15x7s out there (OEM baskets, Beyern, Team Dynamics) in 25-ish et, but I like the tire selection in 16" better - ie. 205/50/16 or 225/45/16 vs. 205/55/15 -oh, did I mention no spacers, stock fenders, and I'm also tired of speedo reading +7% w/205/60/14? Figure I need about 24" diam, similar to stock 195/65/14, hence not 205/50/15, etc @ 23.1,2,3".
Having trouble finding 16x7et25, except $$$ BBS and Alpina. (Would love to have the Alpinas, but don't have $4G+ to spend). Any recommendations?
Thanx!
Find 16x7 or 7.5 +20, there's quite a few now. Try ESM (google 'em).

What tire selection exactly are you referring to? I have 16x7.5 ACS Type 1s and I love the wheels but tire selection at 225/45/16 is slim... and ask my fenders how bad an idea 225/50/16 was...

I am thinking falken 615s at 215/45/16 might be the way I go but would love good 225s..?

Oh, I'm thinking of something more mild - 205s, and there are a number of nice choices in 205/45/16 (Bridgestone RE-11, Michelin PE) or 205/50 (RE760, Conti DW). True, I haven't seen much in 225/45/16 or even in 215.

In my opinion 205/50/16's look too small and don't fill out the guards enough. I've decided to go for 215/45/16 on the XXR 521's in 16"x8" +20.

I just put a straight edge on my tyres and up into the wheel well on the back of my 90 model 318is. According to the tyre size calculator http://www.rimsntires.com/rt_specs.jsp 215/45/16's on ET20 will stick out 1" further than the 195/65/14's ET35 on there now. From what I can gather looking at this, it will be very close indeed. However, perhaps the 45's will have less sidewall bulge and therefore not be an issue.

Exactly my concern. In re:to the 14x6.5 et30 on the car, I estimate the 7.5et 20's will locate a 205mm tread (205/60/14 existing) .9" further outboard (i.e. 1/2" + 10mm[.4"]= .9 I made a similar measurement on my existing set up and at the back, it looks like 1/4" vertical overlap on the inside fender margin; so with camber shift on suspension deflection (estimated by eye) "very close indeed" is possibly optimistic - the tread might clear but the stretched sidewall could hit on maximum upward travel. At the front, the tread edge on 205s already lines up with the inside edge edge of the fender. There's a lot of allowance for travel there (no drop yet on the springs) so maybe it's OK, but it worries me.

JAY, am I off on the math, or will et20 7.5s work with 205/50? Any suggestions for 16x7?

You'll both be fine. Not even close.

Will this setup work?

I will be getting H&R springs, 60/40 drop, with tokico shocks. I need to see whether this will work on my car or what i need to do to make it work with my wheel set up. Thanks for any help in advance.

Ok the specs on my wheels are:
16x7
42mm offset
(16" Motegi R7's)

Tires:
205/40R16

And spacers are 1 1/4" on each wheel.

Does this sound at all like it will clear without modifications?

Yep, will fit fine. Tires are tiny though, expect your speedo to be off a total of about 15-18% now.

8" - 5.25" backspacing - +19 offset
9" - 5.75" backspacing - +19 offset

You'll need to roll the fenders for the 9's. Most likely not for the 8s, but it'll be close.
