I run a 10.5x33w on this car, we only run 10-15 passes on these tires with our outlaw 10.5 car so instead of buying new tires for the bracket car , we just re use these. So with the 33" tire and ONLY running 1/8 mile I don"t think we will crank its guts out. I would be very happy with 6.20's thoe!!!!!!!!!!!
