John lights vary from a little red to a little green. You are right that is why I want a bigger tire. More "green" reaction time and improved ET to boot! Gotta take the "win-win" when you can get them. There aren't many in this sport
By the way I have 15x4 wheels, not 15x4.5. Weld makes a wheel that matches the rear with more backspace. This moves the wheel towards the center of the car by about 1".
