I wanted to share my thoughts with the group.i had put rota rb's on my car and noticed my wheels don't get anyway close to dirty as the factory wheels.I use to wash them and go to town and back and in 10 miles they were dirty.
The Rb's go for days and still don't look like the factory wheels in 10 miles.Never thought a wheel would make a big difference but these have.Just a happy owner and wanted to share.

 

Is it the finish that doesn't attract as much brake dust or the color of the finish that doesn't show dust as much. Take the white glove test.

Or maybe you are just driving slower so that you can be seen with the new wheels more easily.

 

Originals were silver as well as the rb's. and I didn't change any driving habits.I thought others would confirm what I had found.
