When a car is powerful enough, new challenges arise for engineers to tackle. Take, for example, the Camaro Z/28. After running laps around some of the most difficult tracks in the world—like the famous Nordschleife—it quickly became clear that the Z/28’s tires had too much traction and its brakes had too much stopping power.
Well… too much of either of these things is never really a bad thing. The tires are P Zero™ Trofeo R tires, made by Pirelli, and the carbon-ceramic brakes are made by Brembo. This made for a powerful combination that helped the Z/28 achieve up to 1.5 g in deceleration force.
However, that force is so strong that it caused the wheels to spin inside the tire—a phenomenon called wheel slip. To combat the effect, Z/28 engineers tried to apply abrasive paint around the bead of the wheel, where the tire meets the rim. Despite being a common solution in competitive racing, it wasn’t enough to counterbalance the Camaro’s power.
Ultimately, they were able to prevent wheel slip with media blasting. This involved shooting a gritty material through an air gun at the wheel’s surface, creating texture to the paint for the tire to grip.
We hope to see you this spring when the Camaro finally arrives at College Chevy!
