The Brembo GT big brake kit for Tesla Model S RWD (with dual rear calipers) replaces the rear hardware with four-piston cast calipers and two-piece 365x29 mm rotors finished drilled in black. It provides larger-diameter rotors and stronger clamping to improve stopping consistency and thermal management for 2013–2017 rear-wheel-drive Model S applications equipped with dual rear calipers.
