"Congrats on the rims. I was just looking at those yesterday..."
"Nice wheels. Post pics once on the car."
"Those rims are looking goooood."
"+1. Can't wait to see the rims on the car."
"I demand install pics now of the wheels."
"The rims look sick."
First off, do people still refer to wheels as "rims"?
Secondly, replicas and knock-offs are going to continue their assault on the industry until a stand is taken. Make an effort. Make people aware. That starts, simply, by choosing not to praise those who cut corners. I know people love inflating their post count on the forums, but refusing to compliment someone on their fake, used, curbed wheels is a good thing.
