Too bad the mud flaps look cool, but within 5 mins of putting my brand new body on the rear wings of the bumper cracked, it so I think I am going to have to trim the rear bumper down. I just removed my side guards, I broke one, then bought a new set as I took the old ones off I was like hmmm maybe I should just leave them off lol. I haven't raced it since to say if they made a difference for me.
