There is no replacement, at the track, when running true ET drags or similiar slick. I've tried Nitto's 26" DR, BFG 26" DR, ET Streets, and ET DRAG's. DR will work and are great for the street but are difficult to get consistant 60's in the 1.5's or lower. There are locals that are pulling 1.50's locally but it depends on track prep, weather conditions, heating the tires enough, suspension mods, etc.. I'm convinced if you want to run good ET's and good 60's then ET drags is the choice. FWIW most of the TSM class at BG ran ET DRAGS or similiar slick to knock off 9-10s time slips. Just my .02..
