i think have the set up you are looking for. I have a tj running 35's with a low center of gravity and plenty of flex. Im even running stock fenders and do not rub. Its all about bump stop set up. I twist up and loose my flex exactly when i hit mu bump stop. ITS NOT ABOUT BUYING THE BEST PARTS AND SLAPPING IT ON. Its about tuning a properly set up system to do what you want it to do.
