Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (part number 127.47032L) is specifically designed for Subaru WRX models, providing enhanced braking performance through its slotted and drilled surface. The cross-drilled holes improve heat dissipation and help reduce brake fade during aggressive driving, while the slots assist in removing brake dust and gases from the pad surface. The rotor is solid rather than vented, which suits certain WRX applications where solid rotors are preferred for consistent pedal feel.

The rotor features a coated hat finish to protect against corrosion and extend service life. With an outside diameter of 285.5 mm and a nominal thickness of 10 mm, it meets OEM specifications for fit and function. The 5-lug hole pattern with a 114.3 mm bolt circle diameter ensures proper mounting on Subaru WRX hubs. The overall height of 63.6 mm and center hole diameter of 58 mm align with factory dimensions for straightforward installation.
