Brakes are 394 mm (15.5 inch) front and 380 mm (15 inch) rear vented and cross drilled carbon ceramic rotors clamped by six piston front and four piston rear callipers which are among the largest rotors of its type available on any production vehicle.

Inside, the ZR1 gets a 220 mph speedo (370 km/h), boost gauge and lightweight seats. Power adjustable leather trimmed sport seats, leather wrapped interior and GPS navigation are available in the optional luxury pack.
