One of the cheapest traction mods is tire sidewall, get some 305/45s (not 40s), larger sidewall, more flex, better traction and quicker times. You'll lose a tad of speed around corners but bugger all and these trucks are fine up at speed, getting them off the line clean is the problem area for most people. Lose the rubber bands and upgrade to meatier tires, still nothing like old school 305/60 sizes but it's a considerable difference. Plus, your truck looks lower and has more meat in the wheel wells. Worth a shot the next time you need new rears, or, go do some skids and order them tomorrow hahaha.........
i ride 45's too...:rock:
