If I recall the Gran Coupes have a bit narrower rear so may have been able to go 21x11.5 but I went with this set-up as I know it would work for the tire sizes. Front offsets are very aggressive so make sure you have protection on the rockers (+17 if I recall, could maybe cut back like 3mm if worried), rear if I recall is +20 and on the rear I may have been able to go 2-3mm more aggressive. I'm not sure the Carbon Ceramics affect things but I have the CCB's for reference.


We are just doing a project for the Gran Coupe with rear dimensions 21 "x 12 with 325/25 tires.
The wheels will be manufactured on ADV.1 and will be delivered to Germany at the end of April. This should be the first F06 with such wheel sizes.
