Hey guys! I am looking at a set of bbs lm's for my bmw. They are 18" in diameter. 10" wide on the rear and 8" on the front. My questions are:

1. would these be too wide for the arches?
2. Would I run into any problems regarding the width of the wheels and my gearbox? I've heard of people putting alloys on their cars that are to big for the gearbox and it causing major problems to it!
3. Would I still be able to install coilovers with these in or would there not be enough room?

I know these questions might seem stupid but I just want to be safer than sorry!

Thanks in advance!
