I'm look'n to put an anti roll bar on the monte, but i wasn't sure how much movement they allow for(meaning vertical axle movement) the car is airbagged, so rear will see around 8" of travel from time to time, but i've narrowed the frame 6" and the axle , car has factory style suspension, with UMI 12 bolt swap upper amrs and adjustable lower arms, and lower rear drop brackets, so a factory antisway bar won't work, plus i still race the car, but need something to keep from moving. So if any of you all could help that have experience with them i'd appreciate it!
