race in 4wd - u get no where in 2wd on dirt for a few seconds, lolRan with a different XP4 today (2013) yesterday was a 2012 with dry sump, any way the one today had less miles but more weight in it and it was a little faster. The big problem I am having is the gravel is destroying the inside of rear wheels, I have 100 miles on it now and I doubt they will make it another 100 miles before the rims start leaking air. The front tire throws the rocks into the rears and then they grind the hell out of the wheels. Guess we will see what happens!
