I've been a best of 1.59 trannybraked on Nitto 275/50's with my driver. It ran a 12.03 on that pass. My stage 2 powered car has been a best of 1.76 footbraked on 275/60's, car ran a 10.84 on that pass lifting the heads. DR's just take a little more finesse. Transbrake helps IMO to unload the supsension and shock the tire. Was he running a transbrake on the 1.49 short?
