It's been a while since I've updated this thread, but that doesn't mean I haven't been working on my 1-series! I'll make a few posts to divide up the stuff I've been doing.
As you know, I got rid of the BBS LM replica wheels. I wanted to be able to fit more tire, so I found some APEX ARC8s. They're pretty hard to come by because they've been sold out for over a year, but I nabbed a set on Craigslist from across the country!
At the same time, I got an APEX 75mm stud conversion kit. Finally no messing around with lug bolts. I hate those things. Read my installation guide
here.
Anthracite APEX ARC8 wheels
Front: 18x8.5" +45 with 235/40/18
Rear: 18x9.5" +62 with 265/35/18
I added a 5mm spacer in back and will probably try squeezing a 10mm back there instead pretty soon.
