• Staggered Brembo six-piston front calipers and four-piston rear calipers
• Available on the CT5-V Blackwing, the lightweight carbon-ceramic brake package improves heat management, as well as greater resistance to wear under extreme conditions on the racetrack, while also reducing unsprung mass and rotating mass:
  • 53-pound (24 kg) reduction in unsprung weight
  • 62-pound (28 kg) reduction in rotating mass
• High-performance copper-free brake linings
• Brake systems are integrated to each vehicles’ selectable drive modes, including brake pedal feel. Brake pedal feel can also be assigned within My-Mode and V-Mode

A six-speed TREMEC manual transmission is standard on both vehicles and has been optimized for each V-Series Blackwing vehicle. Details include:

• LuK twin-disc clutch for high torque capacity and great pedal feel
• Active Rev Matching accessible via a console-mounted toggle switch to automatically adjust engine speed to match anticipated downshifts
• No-Lift Shift allowing the driver to shift gears without letting off the gas pedal. In the case of the CT4-V Blackwing, it allows the turbos to remain spooled
• Transmission and rear differential cooling – the manual and automatic transmissions use the same track-performance cooling system.
• Clutch and brake pedals positioned for optimal driver ergonomics
• A physical barrier stop for the clutch pedal rather than a hydraulic master cylinder stop provides greater driver feedback during clutch operation
• A shorter shifter ratio than previous generations for more precise shifts

The CT5-V Blackwing and CT4-V Blackwing are available with a 10-speed electronically controlled automatic transmission.

Highlighted features:

• Tap Shift/Manual Mode allowing the driver to use integrated magnesium paddle shifters to select a gear and hold it until selecting the next gear, up or down
