Cathy Belcher's '90 Camaro Nitro Coupe moves smartly off the line, but experienced tire shake a moment later. "We run a Powerglide, which doesn't have the adjustability of a clutch setup," says Belcher. "Tire shake is not good on a Powerglide." The only way to control tire shake, according to Belcher, is to soften-up the power through tuning. Her best ET to date is a 6.56/208.
