16x8 et0 wheels front and rear.
i'm on coilovers so height adjustment is not a problem..
i was just wondering if you had any suggestions for a flush meaty fitment(?).
Square shoulders if possible or maybe a little stretch.

I'm currenty on rubber bands. 205/40/16. (Too low and thin. lol)
If i raise the car it'll look dumb so i figured i might as well get better tires and fitment.

0 offset wheels only fit with silly-small tires.

17x9 all around et22, will 245/40/17 fit in the rear with rolling? How about the fronts?

No, that will rub for sure. 235/40s are possible with a stiff enough rear spring rate.

Fronts are another case all together, you'd need to space them out 8mm to clear the struts and at that point there's only space for a 215/40 max.

even with rolling and pulling? darn i wanted to run at leat 225 in the front and at leat 235 in the back with no rubbing. and i lied they are ET20

I'm looking at a set of staggered wheels. I have an '89 325is with Bilstein Sports and H&R sports.

This is the stance I'm looking to achieve. Neil's car is perfect imho.


Wheels are 16x9et12 rear and 16x8et30 front. What tires can I run on this setup and what spacers to achieve this? I'd like to avoid rolling and get as wide of a tire as I can without doing this.

My second option would be to run a wheel that's 16x8 square that's offered in et15 and et25. What would work well with spacers and wide rubber for a wheel like this without rolling fenders.

I want to still be able to spin this car around so crazy stretch isn't something i want to do.

I'd like to run some Rota RKR 15x8 et0 wheels. That gives me a back space of 4.5" which I think is enough for an e30? They will also stick out 2.3" wider then bottle caps. Could I make these work with some Kmotors fender flares, and if so what tires should I run? I was thinking 205/50 r15 as there are a good amount of choices in that size and it bring the tires close to stock diameter. Suggestions?

Without rolling, 205/45 is the widest tire you'll get on the rear 16x9s. You would need 20mm spacers for the front.

16x8 +25 225/45/16 with a 3mm front spacer.

With flares, sure. 205/50 should be an easy fit.

At first i was gonna be like challenge accepted..
then i remembered buttchug's wheel setup on his turbo m42. He has 205/45/16.
Might be a bit of poke for some.. but it looks good to me!

16x8 +25 225/45/16 with a 3mm front spacer.

So what are the magical end et numbers for front and back running a 225/45/16 tire to get close to flush without rolling? I thought I had heard the fronts needed to be ~et12 and the rears around the same. Neil is running a 16x8 et23 with 10mm spacers in the front and rear...but he is also running a smaller 205/45/16 rubber.

So a 3mm spacer up front gives a final et22 up front and keep an et25 in the rear will give me a setup thats close to the fender edge? Is it that much diff due to the wider tire or...?

Thanks for the help!

So if you were looking to put down major power (turboed car) what wheel and tire set up would you run? Its an 89 coupe btw. Thanks mystikal!

And I bet it's rubbing.

You're at the magical numbers with what I recommended.

Either a 15x8 +20 with a 225/45/15 or a 17x8 +25 with a 235/40/17. Dunlop Z2 either case.

thanks! So whats the difference between early and late model fenders? seems like one is more desireable than the other?

edit: meant rear 1/4's

Hi Mystikal,

I have spent about 20 hours of my life in this thread and have seen lots of good information so thanks already for that.

What I want to know now is a more of your subjective opinion on my setup.

Ordered RS reps in 16x8 +20 front and 16x9 +20 rear
Tires 205/50/16 nankangs all around
I also have some 5mm spacers I can put in the rear

My car is an 1989 vert with hard and soft top on H&R OE sports, 1 spring pad pulled in rear, and e90 hats in front.

I have not seen a lot of people run the 205/50 front and rear and wondering is going to look ok. I have spent the last few hours researching this and I gather that it will work fine I just want to know if it will look silly compared to say 205/45 fr and 215/45 rear which seems more popular (and far more expensive tire wise). Choosing the 50 sidewall was a bit of a practical gamble for me because I live in uptown new orleans and the streets are unbelievably bad, so I figure a little more tire height would help with comfort level of car. My civic running 195/45 on 7.5 inch rims beats me to death.

My car as it sits right now without the hardtop on.....
