If you going with 7-8x18 I think ET20 is the lowest to go.

The average idea of the et is 15-25.
My wheels are at et35 and i am not happy with the way they sit :?

I see now, so if you put a wheel on an E30 with et5 for example, it would stick out?? Is that right :?

with 17" et 25-30 16" same agian 18" you need a 7.5 j rim no wider and 28et offset

it depend on tyre size too, some have a curved side wall which helps clearance under the arch
i'm glad its your head ache not mine!!!

have a stella and think about it!!!!

So if i got 15" or 16" at et20, would i suffer with rubbing at 40mm drop with passenger's?

16" et 24 205/50 tyres 40mm black bilsteins(sports) drop and rubbing!! you gota roll the arches or go for a lower profile. they are very sensetive to offset these e30's

its mad because my old sport had bk171 alpinas 215/40 and the same drop but yellow bilsteins(sprints) and no rubbing!

got 16"x7.5" BBS with 205/50's on.. rub on the passengers rear only.. on a 40mm or so drop

It's alot more than just buying some wheel's as it goes. I don't know if you know but the profile of the tyre is the % of the width. So you have to take in the et and the tyre size to see what will fit and what has to give to compromise what wheel's you want :mad:

Nothing's ever easy :D

8x18" with ET20 work fine on E30...
