Action Plus vs ......... any gains?

You can increase your mph and lower your et by increasing your rollout. Get a 15" front wheel and a larger diameter tire. Run the max air pressure on the sidewall. Stage very, very shallow. On the rear with a street tire run as much air pressure as you can and still hook. If you have drum brakes back the adjusters off a hair.
I'm running 32 psi in the rear and it's hooking thanks to the ever-so-unpopular 30 dollar traction bars :D . I just trip the stage light about as shallow as I can. I have the front tires at 35, and I could go more but when I get to the strip (I drive 1 hour to get there) I do nothing to prep the car. All I do is allow a 20 minute cool down period, and then I turn the key and stage it. A true, 100% in street form car.
