SHW Performance Drilled/Slotted Pin-Drive Rotor 2018–2021 Subaru WRX STI

SHW Brake Systems is an OEM supplier offering the same products to the aftermarket under the brand name SHW Performance. SHW Performance products incorporate a patented Pin-Drive system that offers unique benefits when compared to conventional disc brake rotor design. The Pin-Drive system consists of a two-piece, fully floating disc brake rotor with the friction ring connected to the central aluminum rotor bell by stainless-steel pins which are cast into the assembly during the manufacturing process.

By offsetting the pin connection of the friction ring to the aluminum bell, the cooling channels running centrally through the rotor offer an increase in cooler air flow – up to a 50% cooling advantage over traditional designs. Because airflow is paramount to performance, the lower the operating temperatures, the higher the performance.

Features:

• Up to 5.5 lbs of weight reduction (rotating and unsprung weight) per disc compared to monoblock rotors
• Reduced thermal strain thanks to the friction ring having more freedom to expand and contract
• Reduced brake fade
• Improved durability
• Enhanced brake comfort thanks to optimized thermal conditions
• Curved vane design maintains structural strength while improving noise dampening
