Quick answer

The EVANNEX Slotted 2 Piece Rear Rotor Set reduces weight, heat, and warping for Tesla Model S (2012-1/2020) and Model X (2015-2/2021) with a semi-floating design.

Why choose slotted rotors?

Slotted rotors help dissipate heat and gas buildup during hard braking, reducing brake fade. The slots also allow debris and moisture to escape, which can improve braking consistency.

This set is directional, meaning the slots are angled to aid airflow. Ensure correct left/right installation for the intended performance benefit.

Weight and heat management

The two-piece semi-floating design separates the braking surface from the hub, allowing the rotor to expand and contract under heat without warping. This also reduces overall weight compared to a solid one-piece rotor.

Less weight on the rear axle can improve suspension response and ride comfort, though the effect is subtle for daily driving.

Fitment limitations

This rotor set fits only Generation 1 and 2 Tesla Model S (2012-1/2020) and Generation 1 Tesla Model X (2015-2/2021). It does not fit later Model S or Model X vehicles, nor any Model 3 or Model Y.

The 365mm diameter and 28mm thickness match the factory rear rotor size, so no adapter or spacer is required. However, you must confirm your vehicle's production date range before purchase.

Decision rules for EVANNEX slotted rotors

  • Vehicle compatibility: Confirm your Tesla Model S is from 2012 to early 2020, or Model X from 2015 to early 2021. Later models require different rotors.
  • Driving style: If you drive aggressively or track your EV, the heat reduction and anti-warping benefits are noticeable. For casual commuting, the weight savings alone may not justify the cost. Consider your typical braking demand before deciding.
  • Installation: These are a direct replacement for the factory rear rotors. No special tools beyond standard brake work are needed, but torque specifications must be followed. Have a brake service manual handy or consult a professional.
