Mountain Pass Performance Stoptech STR-60 Big Brake Kit for the 2021-2023 Model 3 and Model Y.

Stoptech STR-60 calipers that are made from forged aluminum alloy, are incredibly stiff, uses a standard pad shape, offers differential piston sizes, and uses silicone dust boots and anti-rattle clips – making the caliper suitable for daily driving

Rotor options include a large 368mm for 18" wheels or 380mm for 19" and larger wheels that give you a wide range of pad options. Since the caliper uses a large pad, paired with a rotor that can dissipate a mega amount of heat, it is possible for most to use a modest sport brake pad compound and potentially not have to worry about changing pads at the track versus on the street.

The silicone dust boots included are rated to handle much higher temperatures than rubber dust boots.

The brake pedal is noticeably firmer as soon as you install the brakes, so all that talk about caliper stiffness isn’t just imaginary. And the response and direct translation of brake pressure to deceleration G’s is more solid and linear than ever before.


Note: The 368mm rotors will NOT work with the OEM 18″ aero wheels, however, it works with just about every aftermarket 18″.
