930M - Winter Wheels
I will be using the Stock 930M rims for my winter wheels which is what I did with my F80 M3. With the F80 I used the stock 9.5” front and 10.5” rear staggered rims (both front and rear were 19s) on a square set of 275 width winter tires which I rotated tires relative to rims every 2 seasons.
For this car I bought two 930M front rim takeoffs from another member in the marketplace so I can run a square winter setup on the the 9.5" rims using 275/35 r19 Nokian R5s. I will hold onto my rear 10.5" 930Ms just so I have a "stock set" when I eventually sell or trade this car. We don't like them now because they are heavy, but they might be difficult to find in a few years. Buy them now while plentiful and cheap

Summer Wheels - Apex VS-5RS
I spent a lot of time looking at rim and tire sizes. The main issue obviously is the weight of the stock cast 930Ms. Secondary is adding a bit of wheel width. Third I want to avoid spacers. I looked at all OEM BMW rims but they have complicated designs that will be difficult to clean with the dusting on these cars. They would also require spacers.
Fortunately for us, there are plenty of affordable lightweight forged wheels out there now, and I don’t want to be daily driving a set of $10K rims worrying about them (Had FI-Rs on my F80). The 5-Y design was easy to keep clean.
I extensively researched Apex, Richland Forged, and VT Forged, among others. I’m an OEM+ person and want to use stock BMW center caps because I like that splash of color on the wheel (to the point I even made my own BMW roundels for my the FI-Rs). All fantastic options but ended up with Apex as I don’t want to spend $1600 on new tires right now, will stick with the 19-20” diameter stagger and not have to worry about fitment or rubbing. Their offsets look great, warranty is great, wheel is strong and light and they are track proven. If I decide to change wheel sizes later on and go to a square setup it they should be easy to pass on to someone else. Well, their Spring Sale helped also. Received the rims and they are fabulous, and very light compared to the 2 front 930Ms I have here. I’m very happy with them.
