I have a black 1999 Chevrolet Silverado 5.3L reg. cab short box. i have lowered it 4" in the front and 5" in the rear, and put 18" KMC Stealth wheels on w/ 255/45/18 nitto 555 extreme tires.
recently, i traded in the '99 and bought an '06 silverado 4.8L 5-speed. my first step will be to buy an LQ9 6.0L, put a bigger cam in it, cool air intake and a few other modifications to the motor and suspension.
