I can get about 50-60 runs out of a set of front tires,infinity in the rear.For the first 20-25 runs,you have a death grip on the world,after that it trails off.Now locally,I can run with almost any car,any class.Nationally,it's a mid pack car at nationals,top few at national tours(in the class).I could buy the "right car" for the class,but why? I enjoy doing what I do in this car,just gotta be realisitic.I like to show up at national events,get overlooked,beat guys I have no business beating,and then tell them it's my only car.I drive it every single day,and it messes with their heads
