Additional track-ready features standard on the Camaro ZL1 include coolers for the engine, transmission and rear differential, cooling ducts for the Brembo brakes, and a high-performance fuel system delivering fuel to the LSA engine under any performance-driving condition. The ZL1's rear axle includes a high-capacity cast-iron-case differential, large asymmetrical half shafts, and extra-heavy-duty universal joints. To keep the lubricant temperature in line, there's an oil-to-oil heat exchanger built into the bottom of the differential. Transmission fluid circulates through that heat exchanger and through the radiator to drop operating temps by more than . In addition, the engine is fitted with the same oil-to-coolant heat exchanger used in the Corvette ZR1. The ZL1 has a deeper oil pan, a longer pickup, and a higher-capacity pump than the SS.
