so you bught an rc touring car to take it off road?
in all honesty you should have really bought an off road buggy because really its designed for off road?
however if you want to take this off road maybe get larger shock towers? im not really into touring rc and know very little on them but physically if you install taller shock towers it should IN THEORY lift the car up as for everything else such as wheels etc i dont know if it will affect how they rotate. it shouldnt be a problem though
just buy a rc buggy its already designed for offroading :P
