While running fast laps at several of the country’s most challenging tracks, Chevrolet Camaro Z/28 engineers noticed the tires were providing so much traction and the brakes so much stopping force that the wheels were rotating inside the tire under the course of a lap.
Featuring the widest front tire in any production car, the Pirelli P Zero™ Trofeo R’s on the Z/28 are outfitted with a track-oriented design. Lightweight Brembo carbon-ceramic rotors were also included – together they help the car achieve 1.5 g in deceleration force.
However, when engineers married the strong performance brakes and tires, they noticed that the wheel was rotating, or slipping inside the tire.
Common fixes weren’t strong enough to prevent the tire slip, so another solution had to be devised. After trying several approaches, media blasting the wheel, which created an extremely aggressive grit on the rim, finally got the tire to hold.
