Well, first of all HRE is not the only custom wheel game in town. They are great wheels, I just can't afford them. I read the other linked thread and it sounded to me (if I understood correctly) that an M3 subframe & hub assembly would only move me inward 10mm. No? Is that correct? For these APEX PS-7 19" wheels to work I need to go inward 1".
The good thing is that these 18" and 19" APEX wheels I have according to APEX's website is the exact offset that they recommend for an E9xM3. So I'm hoping that I can put these up for sale and get back most of my money since 6 of the 8 wheels have never even been driven on yet (and 2 of the 8 are still brand new in the original double-box packaging as delivered). Plus the sale of my custom one-off 1M/135 hybrid side skirts will help recoup some cost as well when I can get them posted up for sale hopefully soon.
