as most of you all know im really trying to make my blaster fast and handle good and i really want to focus on handling cause wats the point of a fast engine but none of the power can get to the ground and its uncontrollable so i wanna get the diamond j widening kit is that the like bar extender things that go on your a-arms cause i see its cheaper than getting wider a-arms so just give me the info on will it be safe or not
