rustler xl-5 waterproof...i bought it 2 days ago. im wondering if i should add suspension clips or spacers..(the little things that came with it) im a full throttle off road kinda guy and im worried that the motor will slap the ground when creating destruction off-road? would anyone recomend putting those on sisnce im not going to buy new shox. if so shout i tighten it up to the max or what? again im new to this rc game so any advice on soft vs. tight susp. would help. pros cons the whole bit. thanx again
