Has anybody installed a Pro comp Nitro kit? 2.5 up front and 1 in the rear. Just curious how it looks and if you are satisfied with the quality/performance of this kit. I am considering this kit or possibly going with the HBS up front and finding a different spacer for the rear unless HBS makes a rear spacer as well? I looked for reviews of the Nitro kit on here but couldn't find anything worth while. Thanks guys.
