So, I own a base 2016 VW Golf R and would like to run the car in B-Street. The base model comes with 18x7.5" wheels, but there's an option package that includes 19x8" wheels. The caveat is that in order to get the 19x8" wheels from the factory, you have to order the Nav/DCC package.
I know about he +/- 1" rule and it mentions standard wheels. With the rule, a Golf R that came with 19x8" wheels could run 18x8" wheels. Since the 19x8" wheels are optional on the car, can I run 18x8" wheels? Or would I also have to add Navigation and DCC?
