I put on a set of Blodi turn signal lens covers because I liked the look but was also concerned about rocks hitting the turn signals and cracking them. I didn't adjust them at all for fit, just slipped them on. They work great and are stable at over 130 mph on the track.
Highly recommend to everyone, especially for those who track to prevent chipping of the lenses.
