In this review the Bendix Premium PRT6909 front rotor is evaluated as a direct OE replacement for Subaru WRX STI models from 2018 to 2020. For owners who want a straightforward, reliable rotor that matches the fit and function of original equipment, this rotor stands out for combining durable cast iron construction with balanced casting to reduce vibration and quiet operation.

Key Features

• OE replacement: Engineered to OE specifications to ensure correct fit, alignment and mounting for the listed Subaru WRX STI years.
• Superior performance: Delivers consistent stopping power and dependable braking feel across normal and demanding driving conditions.
• Heat dissipation: Advanced rotor design helps shed heat during repeated braking to reduce the risk of brake fade on longer drives.
• Noise reduction: Dynamically balanced castings and attention to tolerances minimize squeal and vibration for a quieter brake pedal experience.
• Durable material: High-grade cast iron construction resists the thermal cycles of daily use for long-term service life.
