Anyone looking to add a little chrome to their AMP MT, the Traxxas 1812 roll bar(comes with front/back bumper & roll bar) fits pretty good. The back posts of the roll bar did not reach not the body, so i just used some 1 1/4" screws from the bottom up to reach the posts. The back bumper fit nicely, but the front bumper does not fit. It held up very well the couple times its been to the dirt track/park grass, never tried it on hard surface. It ended up breakin, but it took a direct hit from my sons boost while on its side. Did add clear coat to help with scuff marks.
