I just got my E-Revo today, and I was wondering what the extra shocks are for. Do they make the suspension stiffer, and if so how hard are they to put on?

Also, how do you make it pop wheelies. I am using a 7 cell 4500mAh battery. Do you have to change the gearing or just put it in reverse and then slam it forward. (Will that strip the gears?)

Thanks...
