I got mine from Kolak a few months ago and am very happy. They are worth waiting for. I drove a 96 Cherokee Sport until the frame rusted through. When I bought the WK last year, I was embarrassed to drive around in it because it looked like a suburban cowboy vehicle. The way the WK tilts to the front. Might be good for gas mileage but I don't like it. I prefer a horizontal profile line. I put the 5100s on with the 2 inch setting up front, and put 2 inch Rusty's spacers on back at Kolak's suggestion. The back spacers in fact only give around 1.75 inches of lift, which helped to level the WK. I like it now, and the 5100s noticeably improved the handling.
