Just had nice, informative conversation with Corey at Apex.
Here is what I learned:
They have a native front fitment 19x10 ET20. At more than -2F, they recommend a 3mm spacer. The Apex forged wheel has a thick lip and they would like a little breathing room between the lip and the strut.
They also have a 19x10.5 ET25. It’s a BMW wheel, but with a centering ring, works fine with Blackwing. It does need a 8mm spacer, but will allow you to run a 295 size front tire.
Rear fitment is a 19x11 ET44. Also need a centering ring and they recommend a 3mm spacer.
I think I am going to spec the 19x10 front and run the 275 RT660. After I get comfortable and are certain there are no issues, I’d give the 19x10.5 with a 295 front. A lot more options in the 295 than 285.
