Is that an Ofna GTP bumper on the MBX? Also those body mounts are very nice! they must help hold the body up great!
Mine seem kinda weak, but the car has cartwheeled and tumbled at high speed and its held up perfectly, especially for Maxx and stampede body posts. My dads GTP posts actually broke quite frequently. ( but he did hit a curb at 3/4 throttle and his car litteraly flew 10-12' up and a good 20' out before rolling like crazy!

It was quite a site!) he needs to get another set...
Looking again, I really like that body and paint scheme you have! Cheers!
