4 Link Top Bar Changes with Level Lower Bar to stop crushing slicks will show you how the top bar can be tuned to stop from killing the sidewall of a big or small tire slick! 4 link tuning is not magic and these principles apply to all 4 links, at a high level. Understanding 4 link suspension is a great tool to have! Remember the anti squat line is a tuning aid and each drag car is unique. Stop crushing your slicks. Your instant center in relation to your car's center of gravity is very important.
