Been a while! After much nothing doing, I finally lifted my Jeep with the SkyJacker 2.5" coils. I gained closer to 3" of height on my 2 door JK with these. New shoes are Cragar soft 8 15x10s with 4" backspacing, and 35x12.5r15 BF Goodrich Mud Terrains. Also bobbed my front bumper. The 3.21 gears are fine with the 35s, I was worried for nothing. It is still plenty peppy on the highway with the 285hp Pentastar motor, especially on a 2 dr. I had to clearance the front calipers a tiny bit to fit the 15x10" wheels, nothing major, mostly just the flashing from the rough casting. Drove through alot of deep soft sand this weekend, it was a beast! went up dunes and all, never needed 4-Low.
