It’s a fact that the Chevy Camaro Z/28 has the widest front tires of any production car. At 305 mm wide, those tires produce tremendous grip–especially since they’re Pirelli P Zero Trofeo RS. In fact, they make so much grip, the Z/28 was spinning the tire around the wheel under braking–the Z/28 was, in effect, outrunning its tires, or at least their ability to grip the wheels. It’s an unusual problem for a production car, but it’s a good one to have–too much grip is just enough.
Camaro Z/28 engineers had to come up with a creative solution to prevent tires from slipping on the rim during hard braking and acceleration on the track. Part of the cause also comes down to the Brembo carbon ceramic brakes, which provide tremendous stopping power for the large but track-worthy Z/28. But regardless of the cause, Chevy had to find a fix for the tire-on-wheel slippage issue. If Chevy hadn’t found a solution to the problem, it could have resulted in the wheel/tire package going out of balance–like the wheels they’re mounted on, tires aren’t perfectly uniform around their circumference. That’s why the wheel/tire package is balanced as a unit. Typically, Chevy says the tire-wheel slippage issue is solved through the use of an abrasive paint along the bead of the wheel, where the tire seats. The Z/28 team tried this, and found it wasn’t enough to prevent the problem. Want to know what finally worked? Check out the video above and the rest of the story at MotorAuthority.com
From Exhaust Gas Recirculation (EGR) Valves to O2 Sensors, your exhaust system has a critically important job to do to keep your car operating efficiently. Your vehicles exhaust system is engineered to withstand extreme conditions, including high exhaust temperatures, corrosive gasses, road salt (where applicable) and water. The vehicle’s exhaust system performs three important functions. It directs exhaust gases from the engine to the rear of the vehicle, it treats the exhaust gases to reduce emissions and it reduces noise produced by the engine’s combustion process.
It’s no surprise your vehicle will drive better if all the wheels are pointed in the same direction. That’s called wheel alignment. What might you notice first if your wheels are out of alignment? Usually it’s that your vehicle pulls to one side or the other. Now, something you won’t notice right away but will if you keep driving when you’re out of alignment, is your tires are wearing unevenly and fairly quickly, and that’s not good. When your vehicle is pulling to one side, you have to steer it back straight.
