front wheel fitment

Kizzu · 10-11-2014, 09:39 PM

Will 18" 9 et45 work on the front of a 1er? Planning on 245 tyres. Will I have anu issue?

you're gonna have a lot of clearance issues... and you'll definitely need a 10mm spacer...

try a 18x8.5 et 45-50 wheels on the front with a 245 tires.

Kizzu · 10-12-2014, 01:06 AM

10mm? That will give me 35et on a 9. Will poke too much. Thing is that I saw a square set and I m really interested on them but have doubts on the fronts.

Pyrat 2 · 10-12-2014, 07:38 AM

I believe a 5 mm spacer will do the trick. I have 8.5 et45 wheels with 235 front and 245 rear. MPSS. For fun I swapped front and back to see if I could go 245 square at my next tire purchase. The fronts spun freely but with a constant slight rub on the strut. I bought some 5 mm spacers and they are sitting waiting for me to try them.

Vmr's and apex make 8.5 et45 fronts with no rub at all. I guess that's tyre width difference though. That said, yours are 8.5 the wheels in question are 9". Thats half an inch wider than yours and with no rubbing on 8.5's I think that half an inch more would rub. That's the whole dilemma.

Pyrat 2 · 10-12-2014, 09:00 AM

Yep. The tire is rubbing and not the wheel. So doing the math. Your wheel is .5 inches wider which is 12.5 mm total width or 6.25 on each side. So long as I have at least 1.25 mm spare between strut and wheel (which I do) then a 9 inch with a 5 mm spacer will allow the wheel to fit. Rubbing on the inside or outside will be determined by the tire size. Make sense?

Btw the wheel fitment calculation above assumes that the strut diameter is the same on your car and mine. I'm running Bilstein sports so I can't say for sure whether this is the case.

Eyeman · 10-12-2014, 10:20 AM

Y'all are dead on with the calculations. I have 19x8.5 et42 and my wheel is 3.5mm from my strut. I'd think 19x9et45 would need a 7mm ish spacer to make sure the wheel cleared and then if the tire sticks out at all you'd need to add that to the spacer width.

yes I got that part about the inner side of the arch. the question now by doing this 5mm spacer is that how much out will the tire poke? got it?

my concern is that once the strut is cleared the setup would poke out. that's mainly what I'm worried about

Pyrat 2 · 10-12-2014, 04:26 PM

Doesn't stick out too much with 5 mm. However, I have -1.5 camber so rubbing is not an issue. Can't say whether the wheels will be out too far for your tastes. Tires will determine whether you have a rubbing problem unless of course your car is dropped far enough for the wheels to come in contact with the fender on a bump. Recommend seeing if you can borrow some 5 mm spacers from someone for a test fitment.

You're clearing with 8.5" et42 with no spacers on stock suspension correct? If so mind telling me what tires you're running?

Eyeman · 10-13-2014, 06:44 PM

3002ti, my mods are listed in my sig. PSS's run fairly full. I'd bet a 235 would be slightly rub the strut and for sure would rub my fender at times.

Kizzu, I was just trying to get you past the strut. As you know, rubbing the fender will consider heavily on how low your suspension is setup and how much camber you run. To run that setup and not rub the fender I'd think I'd start at 3deg camber on a normal height suspension, more if lower. Then drive carefully until you figure out how much you rub.

Kgolf31 · 10-13-2014, 07:30 PM

Just for another data point.

17x8.5 ET40 + 5mm Spacer (Effectively ET35) with a 245/40/17 Hankook RS3 Tire (Effectively a 255 tire on a "normal" street tire)

Running -3.6* Camber, lowered severely, and they fit.

You're going to be pushing it with a 9" wheel, but they will fit.

I am willing to roll fenders if that helps but I am willing to put 245's front and I'm guessing that with increasing width I will have to put a thicker spacer (more than 5mm) therefore putting the wheel further out the wheel arch :/ I'm a bit confused with calculations. On the other hand, great setup. Saw your suspension setup somewhere in here. Is 3.6 camber too much for a track setup?

If you're currently at a ET45, you need a 10mm spacer to be where I am at currently as pictured.

I needed to run ET35 because of coilover clearance, you may be able to get away with less if you're on OE suspension.

3.6 isn't much for the track, BMWs need as much camber as possible. If I could get more, I would do it.

Planning to run on bc br's and m3 control arms. Do you have uneven tyre wear with that setup though?

Not really.

There is some wear due to camber but if you run 0 toe you won't wear as quickly as a typical alignment.

5mm spacer worked just fine.

You're also running a 225 tire.

Big differences, You would not be driving that car with a RS3, ZII or like tire in a 245+ size.
