sorry I just noticed your post now. To answer your question the imagines only come with a +40 offset And that wont fit!!!! So what I did was bought a hubcentric spacer (that or nothing!!) and longer bolts!!!!!! (this is a must!!!! and trust me on that one) and wala. Spacers are a must with 18"s on bmw's well..... maby not but i can only think of 2 wheel manufactures that make ower offset and the rims are ugly anyway. See the problem is 4/100 bolt patern is a front wheel drive offset and ours is rear wheel drive this is also the same for mid 80's mustangs the 5.0 liters. I dont now why bmw did that but it makes it a pain in the ass to find the right wheel offset!!!! p.s. the spacers is only .25" thick 5.5mm.
