I can't remember who originally came up with this mod, but here it is.
You need some pieces of very stiff but still plyable foam ( this stuff came in my TV Box) and you cut it to fit inside your front and rear bumper between the bumper and the brace like this.
The boy runs into stuff at full speed all the time and the braces have yet to show any sign of damage.
These are the most usefull ones I think, I have some more small ones, I will post them if wanted.
Like how to make dish wheels look better, cleaning a Mamba Monster, some conversion/battery info by Bondonutz, shock tuning by Bondonutz, A home made tire balancer, a huge list of helpfull sites etc.
Hope it helped you guys, as much as it helps me!
