hey whats up? welcome to the site! I have 3.5" calmini lift and i raised the torsion bar another .5" and mine handles fin on the highway. I get about 14-15 miles per gallon and I have 32" tires. On the highway mine is a little bit noisier than it was before the lift but that is because of my tires. o dont forget when you go offroading after you put the lift on if you are goin to do anything serious to diconnect one side of your sway bar. It will give you more articulation and It will keep you from snappin it. I just learned that the hard way. Newho hope thids is what you wanted...
