Jeep models score differently on the CTI. My old TJ will probably never out flex a well built JK (or now a new JL). Wheel base has a little to do with it, but the key is to take your score, after evaluating what the Metalcloak folks told you were your "hangups" in your jeep scoring higher, and decide if YOU want to spend the time and money to score more. And we all know, it's not the score -- it's how the score relates to your style of wheeling. With my Metalcloak dual rate coil springs and Rock Sports shocks, combined with all my other steering and linkage mods, I score in the high 800's. But that's after 4 rebuilds.
