Sport Rotor Kits

Direct replacement performance discs for your factory brake system

All our rotors provide improved cooling and are designed to offer significant braking advantages over OEM parts with a number of innovative design details that result in optimal stopping power. 

The purpose of a 2-Piece rotor performance upgrade is to reduce weight and increase ventilation and cooling, while retaining the original dimensions in most cases. These Rotor Kits can be up to 3,6 kg lighter and ensure faster acceleration/declaration, braking and handling.

Why you should upgrade your rotors

Typical OEM brakes are designed for cars with standard engines, performing routine tasks: the morning and evening commute, grocery shopping, driving the kids to soccer practice, etc. In other words, your OEM brakes can easily become overwhelmed.

Performance rotors are direct replacement discs for your factory brake system and stock calipers. They offer improved cooling as well as other advantages the OE rotors just don't offer.

Slotting and/or cross-drilling helps wipe away the debris that forms between the pad and the disc, adds more bite, and can help the rear brakes to match the aesthetics of a front big brake kit. The rotor finish helps prevent glazing of the pads and improves wet and dry braking performance.


Advantages of a 2-piece rotor over a 1-piece rotor:

The primary purpose of 2-piece rotors is to reduce unsprung and overall vehicle weight. This is accomplished by using two-piece disc construction. The 2-piece design also allows for independent expansion of the rotor and hat without coning. The secondary purpose is to increase the ventilation and cooling capacity of the brake disc. Better airflow means better cooling and less fade.
