I have a 2011 GT 5.0 with 6 speed manual. 3:73 gears weighs 3400 lb. just had supercharger kit instated and is making 677 HP and 575 ft lb torque on Dyno. I am running Nitto 555r on it. 275/40-18 and not getting enough traction. I am wondering what is the best sticky tire I can put on it for street and track grip. I want to stay with my 18 wheels. They are 10 inches wide.
Help, need lots more traction!!!!
