I have a 8.5 in front and 10" in rear. The tire/rim combo is properly set up. I thought about the relo brackets but I don't want to get too deep into sinking money into "may work" solutions. I really don't see too many other options than what I already have, for the street that is. Maybe I just have to get accustomed to what I already have. Every car is different.
Last sentence you wrote is key. The Challenger rt is heavier, less powerful and has a different rear suspension than a Mustang GT which is lighter, has more power and has a different suspension.
Tires are one key component to hooking up. But driving technique is as important. Two different cars require two different techniques.
