Apex Wheel Sizing Advice - M4

[rborane]

Trying to decide on sizing for a set of ARC-8 wheels for my M4. Which of the following would you go with?

Sizes:

A) 19x9 et28 with 255/35/19 (w/ 12mm spacer)
19x10 et25 with 275/35/19


B) 19x9.5 et 22 front
19x10 et25 rear


C) 19x10 et25 (square setup) with 275/35/19 all
around


What are the benefits to a square setup? I don't track (may eventually) and use it as my daily driver with spirited weekend runs.

There's no real benefit to a square setup if you don't track.

Why ARC-8 though? They have a relatively small barrel diameter. The 18" won't fit over the regular brakes and the 19" won't fit over the CCB.

The EC-7 have a larger barrel and so do the new lower weight offerings.

I use 18x10ET25 with 18x11ET44 EC-7 as my track wheels.

I would try to do 9.5 and 10.5 for the street

I was looking at the ec-7 as well. Not set on the arc-8 although I've always liked the look especially from when I had an e92.

Apex kept recommending me to a square setup, which is why I figured I would gauge opinions here. Main objective is I want a quality wheel that will look good and have similar stance as the 437M with 12mm spacers I have now, on a street tire. Not sure which width to go with front rear, 9/10, 9.5/10, 9.5/10.5, 10/11.

I want to start going to the track, and making that a hobby and will probably eventually get track dedicated 18's like you.
