I put them on my VR 2 months ago, but would have been happier if they came with a contrasting color. 2 weeks ago, someone, not on DC, began offering inserts in white, yellow, silver and another 1 or 2 colors. I put the white inserts on today and am very pleased.
The 427s from GM look really great on the other colors, but didn't stand out enough for me. They do now.
