Thats fine, your only the 2nd person to say that since I put the wheels on! Better than the RS replicas IMO, and the vent on the NS is functional with the filter in the bumper which is the main reason why I fitted them, to allow more air into the recess and hot air out.

The wheels were originally intended to be track wheels only but they turned out so well after blasting and coating that I kept them on for general use, personally I love them, and the original wheels too.
