What would be needed to fit
RS 003's origional ET on a 7j wheel of 25.
These have been built out to 9.5j rears and 8.5j fronts.

Rav

16x8.5 +5 and 16x9.5 -7? Heavily pulled rear arches, lots of front AND rear camber, and the smallest tires you can stretch on (205/40 and 215/40 is good).

i saw e30robs spacers andit sparked my curosity for these.

Those are 15s. If you really want to run them you can with Rob's adapters, but there are plenty of 4x100 15" weaves that look exactly the same.

lol...yes and no. You will gain lateral and longitudinal grip, but the wider-than-optimal wheel to tire ratio will slightly dull response time. Still worth it to me (I run 225/50 on my 15x7's).

That's in line with what I was expecting you to say. I've run 215/60/14s on 14x6 caps before, so I think it'll be better than that.

My 89 325i has two new falken ziex ze 502 205 40 16 in the front and bald falkens in the back. There on Lenso BSX which i beleive are 16x7.5. I cant seem to source the falken 502 - 205/40/16.....Should i just try and by the same size tire in the back and call it a day or would you suggest purchasing a different tire size? Any tire recommendations ?

Okay, I'm asking this for a friend and I don't feel like reading 3800 posts. He has a late model with unrolled fenders. He is going to install eibach pros so they won't be stiff and he is running a 15x7 et12. He currently has 195, 55's and we know 205, 50's shouldn't have any issues. Would he be able to run anything wider without having any rubbing issues? If they were et20 or so I don't think it would be a problem but he is concerned due to the lower offset.

E36 5 lug? Which coilovers? Your setup is unique enough that I may not be able to give you a precise answer.

Yes, E36 5 lug. B&G coilovers.

16x9.5, et 35 on an E30, 5 lug with coilovers. What kinda spacers are needed?

If you cant give me a precise answer, something that will be slightly stretched, but have the same overall height will work just fine for me. Thanks!!

So I'm getting ready to pull the trigger on rubber for the E30 M3 and in my searching I have come up with a few questions. The wheels are staggered Hartge Type-A's in 16x7.5 Front and 16x8.5 Rear.
At first I really wanted to run a square tire set up with 225/45R16's. Now however I'm thinking of going with a staggered set with either 205/55's or maybe 215/40's in the front with the 225/45's in the Rear. Would the square set up look too wonky on the staggered wheels, there's only a 1" difference after all. If so, what would be the best option between the two front sizes? FWIW, Hartge originally mounted 205/45's Front and 225/45's Rear (as shown in pic below). I'd like as little difference in contact patch between the two axles, and as much understeer prevention as I can get.
As for tire selection, I'm pretty much set on Toyo R1R's, but the BF Goodrich KDW-2's are significantly cheaper and seem to get pretty positive reviews. The Toyo's would only work on the square set-up too due to their smaller size selection. Are the Toyos really worth the extra cash over the BFG's?

You are gonna need at least 20mm spacers with those wheels. Never heard of a 201 section width though...

trying to fit a 225 45 16 on the rear should i go et15 or 25 ? dont mind rollong the fenders but dont want poke.lowered with h&r race.

thanks

I can speak from experience, go for the 25. I run the TRM C1's in et25 with my 225/45-15's.

Lowered suspensions may need some rolling in the rear, front on my drop kit is all the way low with no issues.
