Picking up some 15x9 et15's all the way around, this is the stance I have not anywhere near ultra slammed as this car is mainly used for auto-x. Would like a tire that will fill the fender and not have the "stretch look". Will I need fender work as well? Thanks in advance.

205/50 is the safe best. 225/45 if you have a fender roller for the rear.

Ok... I guess my day has come.

I am looking at a set of 16s for the 30. rolled fenders and the few sets that i am looking for at this time are 8 wide. What would be a good et for them?

I will also be running some neg camber and all that jazz being the car is stupid low....

As you can tell by my sig i currently have the esm reps that are 15x8 et 10 all the way around. I love the fitment in the rear, but the front could be a little more flush....

Curious as to how this will change with 16s.

+10 is fine.

Bought another set of wheels for track/street use.
Wheels : SSR Type C's 15x7 +38
Suspension H&R Race and Billy Sports with e90 drop hats

What size spacers would you go with for a "decent fitment". Not looking for any hellaflush fitment but looking for something nice too look at more importantly not rub because they will be tracked on as well. Also, 205/55 or 205/50 with this setup?

Thanks in advance.

20mm and 205/50. 205/55 is a dead size now.

A question for the wheel fitment guru:

• The car: 1991 M3
• Suspension: H&R Sport, Billy Sports, stock camber, stock sways
• Rims: E38 Style 5, ET 23, 16x8
• Tires: 225/45
• Non-rolled fenders

Do you know which are the correct spacers to clear the front caliper rattle clips? I am assuming 5mm.

How about the at the back to bring the rears in line with the fronts? 12mm?

Thanks in Advance!

I've heard as much as 10mm depending on pad thickness. You will have to experiment.

We are building a lemons "race" car. ATM we are thinking 16" wheels to help with the cooling. We plan on using Turner 3/4 degree fixed camber plates, w/turner race springs & Bilst. shocks. Stock brakes. What will be the best set up for max rubber on the ground and best overall handling. We look foward to rolling the fenders to the max.

Let me correct that last paragraph... We are on a tight budget. What type of wheel would you run in our situation (tirerack.com or other options >$1,000/6 wheels)?

Thanks,
K

ps- phenominal thread. Thanks for all your help.

Run 15s. See the Tirerack 15x8s, they're light and cheap.

I have a question...

I want my e30 to be aggressive for autoX, but driveable on the street - I dont mind roughness.

Car: 88 325is
My Suspension: GE coilovers 450/650lb rear - shortened housings on billy IX
Wheels: TR Motorsport (Tire Rack Wheels) 15 x 8in

Look I am going for: I want a flush look, and I want the car to sit low (I should have a skidplate in the next few weeks). What spacer do I need for it to be flush with a tire size between 215-245? I dont want anything flashy obviously; just an aggressive, tucked, look with a nice thick tire that will fit in a leightweight 15 x 8 wheel with studs and will perform beautifully.

I am thinking I need a 12mm spacer perhaps and a slight drop using the spring sleeves. I am also hoping to go 235/45 maybe. Does this sound about right?

225/45 Hankook RS-3. When you look into 15" tire sizes you'll see this is the choice.

16x8
+20
245/45/16 in rear
Fenders are rolled
How would that go?

Lots and lots of rubber on your quarter panels.

[Mystikal]

Here's the wheel:



16x8 +15 for the front
16x9 +18 for the rear

Will I have any fitment issues? My fenders are not rolled or anything.

195/45 front and 205/45 rear. Won't need any fender rolling with those sizes.

Okay, thanks man.

Ok I have a set of 16x7 rota's that i plan on mounting on an 87 with eibach suspension. wondering what spacers i need to fit these on and what is a good size tire to use? I'd like to get 225/45s. i got a turbo'd m50 so traction is a problem so the bigger the tire i can get under the better. I'm planning on going with the bfg gforce kdw. Also on the wheel it say offset: 40, and i measured the backspacing and its 5 and 9/16! Any input?

Will bbs rs 16x8 et 11 and 16x9 et 8 fit with the 18mm or greater adapters? Also what tires would work well? I have my fenders rolled but not pulled.

That makes them ET-7 and ET-10. I'm no expert but I think that won't fit without arch work.

Need to run this by the Guru before I make a purchase. I want to put some meat under the car, looking for a wide stance and traction to accommodate my swap. Due to some wrinkles I will be adding flares so making the size fit inside the stock fenders, rolled or not isn;t an issue.

16x9 et 0
265/45r16

in all for corners.

Will I have any fitment issues or need for spacers.

Thanks,

Thats one goofy tire size.I'd go to 17's and then you open up your choices for sizes by about 1000 times.I'd bet going to a 5 bolt swap/adapters will also allow more options in WIDE 17's to fit those WIDE tires on.

Yeah not to common, but they exist, Kumho makes there XS tire that size. I don't disagree with you on jumping to 17's. But the price tag also jumps quite a bit as well.
