I had a 2002 4.4 with sport and had staggered not quite as big I think I only had 255 front/275 rear and like you said it felt planted. I now have a 2013 with M-Sport but this with 20" 275 front 315 rear. although its not as every pebble feeling like the 2002 it is certainly no disapoointing in any way. as said above get staggered it makes a world of difference. One question though why would spacers be required on this setup?
