Driving and Operating Z06, ZR1, and Grand Sport Coupe manual transmission Only: For racing or competitive driving, it is recommended that the brake fluid be replaced with a high performance brake fluid that has a dry boiling point greater than 279°C (534°F). After conversion to the high performance brake fluid, follow the brake fluid service recommendations outlined by the fluid manufacturer. Do not use silicone or DOT‐5 brake fluids. Z06, ZR1, and Grand Sport Coupe manual transmission Only: For racing or competitive driving, it is recommended that the loading of the vehicle be limited to the driver only, with no other cargo, and that tires be inflated to 180 kPa (26 psi) for a maximum speed of 230 km/h (143 mph). If the vehicle is a Z06, ZR1, or Grand Sport Coupe manual transmission model, it has greaseable outer ends on both of the rear toe‐links. Under normal use, lubrication should be performed as described in the maintenance schedule. See Maintenance Schedule on page 11‑3 and Recommended Fluids and Lubricants on page 11‑12. If using the vehicle for racing, lubrication should be performed at the end of each racing day. See your dealer for lubrication and make sure any needed repairs are made at once. 9-7 Proper procedures for performing these services can be found in the service manual. See Service Publications Ordering Information on page 13‑18. If the vehicle is used for racing or other competitive driving, the rear axle fluid temperatures may be higher than would occur in normal driving. We recommend that the rear axle fluid be drained and refilled with new fluid after every 24 hours of racing or competitive driving. See Recommended Fluids and Lubricants on page 11‑12 for what fluid to use.
