Weight transfer during acceleration or braking is inevitable. Sure you can stiffen it up or raise the rear a bit to help combat it a bit but it's not going to help stop wheelies much if at all if that's what you're after. To combat wheelies you need to look at Punch Control, longer chassis and/or moving the weight forward and most importantly your own throttle control. I don't care who you are, taming 6s takes some finess on the trigger. My LST XXL is 1717 powered on 6s and it takes some getting used to but as my sig says, "I don't need no stinking punch control"
