New rims, need spacers

[xLibelle]

The rim is 16x7 with 40mm offset. The wheels are on the way, so i havent measured yet, but what size spacer do you think i might need?

 

[wood_e]

dunno, but I do have 1/2" spacers and 1/4" if you need them. What is the bolt pattern for your BMW?

 

[xLibelle]

Lug is 4x100.

Here is a question, what is the offset on the Bottlecap rims?!?
I thought they were 25, the guy at Bav Auto says they're 30 and ive read online that they are 35. wtf!

 

[xLibelle]

Ok, so i have found out, by having bought washers and trying them out, i determined i need 8mm. BUT, i think there is a bigger problem at hand.
PLEASE HELP

first of all, here they are, well, two of them for that matter.

The thing that i am worried about, is that i bought too big a tire! uhg - 225/50/16!!

and thats WITH the 8mm spacer

They fit nicely, but i dont know what will happen once teh car takes a dip. I did turn the wheel and they scrub on the inside and out of the front.
PLEASE, any words of advice? [???1]

They look good tho. (they are silver btw)

You should definitely take the big sticker off of the front tire.

They look good. If you lowered it it would look great.

Sorry but i can't help your problem.

 

[xLibelle]

well, that was just a test, they were backwards too.

But i reordered them to be smaller 205/50/16.

Now im stuck with the spacer issue again. I determined that 8mm would keep it from scrubbing the strut and under the fender, but the dealer actually recommended 20mm spacer! which would garantee that it wouldnt scrub when turning, but wouldnt that make them stick out the sides?
8mm = just enough to fit, 20mm = recommended, so would 15mm be right?

Here is the rim with 8mm spacer. by this, does it look that i should get 15mm??

After everything is installed, you might want to consider the BMW mud flaps whether you like them or not if the wheel protrudes in order to protect your paint. By the way I like those wheels a lot on the E30. H&R as well as others make quality spacers and make sure you get the right lug bolt length.

did you have to get longer studs with those spacers? I got a set of 18x7's I'm gonna put on and had to get 1/4 inche spacers and the distance from the shock in the fron looks about the same as yours does, maybe I little bit closer

 

[xLibelle]

of course - i think i got 40mm but with 1/4" spacer, you can use 35mm bolts.

but an 18" rim? you have to be kidding. what size tire do you plan to use and have you even sized it out yet?

UPDATE on my spacer problem, i am most likely getting 10mm spacers fabricated by a local metal shop. (i would have done it myself with it having come to this point, but i need them by next week)
If they turn out to be cost effective, anyone want a set because i just might order quite a few if they come out right?

 

[Hupp]

at the local performance shop here in town the guy has a set of 215/45/18's that are used and I talked him into letting me borrow just one and getting it mounted then put it on the car and see how it will work, I think it will be alright, might rub sometimes but that's ok with me

 

[xLibelle]

talk about scrub

 

[Hupp]

well I'm not gonna go buy a set of tires then find out they don't fit

 

[xLibelle]

did you think about that when you bought the rims?

 

[Hupp]

yeah, I got a really good deal on them so if they don't fit I'm pretty sure I can get at least what a payed for them

 

[xLibelle]

So here they are, in all their glory, 10 mm aluminum to my exact specs.

gotta get the other two tires mounted tomorrow.

In conclusion, here.


thanks for.... not much help guys. I know a lot more about this now so i guess i am the spacer guru.
