Does anyone know the differences between the NT05R and NT555R? the 05r looks more like a true cheater slick while the 555r looks like a more normal street tire with a stickier compound. Based on looks the 05r seems to be the best for traction. I don't drive the car in the rain, and I only drive about 2k miles per year so I don't mind them wearing out fast IF the traction is much better. I'm mostly concerned with straight line launching on the street and plan on going to Byron dragway a few times a year. I currently have BF Goodrich all seasons (285/40/17) and with my 5 speed and 4.10 gear they spin pretty easy. I am adding a 75 hp shot of N20 and a Cobra intake so they will spin even easier. Finally, I have the original 15x7 turbines so I could turn those into track only wheels with tires, but I still want traction on the street with my 17 inch wheels.
