I've got a Cuda, and I'm running on the same rubber as NZ, only 235/60 in front. And NZ... again.. can't get enough of Lucy, she's a beauty.
Edit: Forgot all about header to ground clearence, to put it this way, my headers are banged up, but that has nothing with the tires to do. The shocks was totaly useless. Now I have bought new TTI's and new shocks and Hemi torsion bars to keep them from smashing into the ground. You can adjust your clearence with the torsion bars.
