Hi guys,

I am getting a 2015 428 xdrive Gran Coupe in a couple weeks here and want to get some summer tires on them however need some help. I want the 18" Niche Apex M126 rims. http://www.nicheroadwheels.com/apex-m126--w-5270.htm

My issue is that I want the concave look all around and they have two option of rims:
18x8 et+15
18x8 et+40

I don't believe the +15 will work, correct me if I am wrong. So would have to get the 18x8 et +40, but don't think this has much of a concave look.

Other option is to go 18x9.5 et+40 assuming it would be more of a concave look than the 18x8 et+40, again correct me if I am wrong.

Wasn't planning to go for a staggered look, rear 18x9.5 front 18x8, but not sure if the front can even handle 18x9.5.

Any advice, suggestions and opinions would be much appreciated.

Thanks
