Mine has gone the best of 12.50 and is a completely street legal complete car. Full interior,working wipers,radio, heater,lights,column shift,full exhaust out to the tips(never unhooked). The only thing I change at the track are the tires and thats just for practical reasons but it hooked well with drag radials. The rear tires I use are Hoosier Quick times but why ruin them on the street
