I'm considering a new 4.4 Prem,Sport pkg with 19"wheels or new 4.8 (20" wheels and sport included) Question is the ride diferrence? I have driven both but only for short distances as demo rides. My driving is mostly "in town" on decent roads. My concern is from searching this wonderful forum that the 20's on the 4.8 may give a slightly "harsher ride while being a litlle "quicker" Thanks for you thoughts.. Allandpm
