I would go with the Yokohamas over the Dunlops. We have them on our '95 626 with 44,000 miles and we are on our third set! I have had good results with Yokohama tires (Yokohama S305's) on my old VW Cabrio and currently with my 84 4ksq, but I haven't owned Avid H4's. Hope this helps. Scott Mallett w/ a sick 84 4ksq
