The upgrade stuff is tough. This is my second one this year so far. It all depends on how hard you crash and what crashes into you. The skins clean up good and it takes a lot to tear them up. I usually race 2-3x per month and they hold up for 4 months or so of that kind of abuse. Sometimes I tend to crash a lot too. I like them though. Now the starter box skin will last forever. I had one last well into 2 years with minimal signs of wear.
