Thank you Matt. I found some wheels I really like and have decided to go 18" instead. The car already comes with 19s and would like to go the 18" route with lighter wheels and wider tires. These are hub centric and use factory center caps.
These in 18x9.5 et 22 front and 18x10.5 et 25 rear.

I would love to go with stock 18 inch sizes I have been told they will be stretched in the rear so looking at:
265/35/18 front and 285/35/18 rear - Michelin Super Sports. Do you have any thoughts on this setup?
