Girodisc Slotted Rear Brake Rotors for 2018–2021 Subaru WRX STI (rear pad trimming required)

Description

The GiroDisc 2-Piece Slotted Performance Brake Rotors replaces the OE brake disc without modification. The disc bolts to OE calipers. Instead of a brake kit, these are lightweight and high-performance brakes, which maintain factory bias and ABS efficiency.  Due to the 2 piece design, these rotors are going to be lighter than stock.  A reduced rotating and unsprung weight enhances acceleration and suspension response.  If you want the best, a 2 piece rotor design will always be the best option.

• U.S. 6061-T6 aluminum makes our rotor’s center hat.
• Girodisc’s cast iron and in-house machining make the disc.
• Racing-inspired curved vane rotors cool the disc.
• 2-Piece Slotted Performance Brake Rotors use 8 or 10 cadmium-coated high-strength steel-driving pins made in the USA.
• GiroRotors retain brake bias and ABS with OEM calipers.
• Pins maintain axial and radial float between hat and disc while braking. 
• Includes cap screws to protect pins.
• The rotor side pins have anti-noise spring washers to prevent cold rotor noise.
• Rotor expands with heat without rattling or noise.
• Float design self-centers the rotor.
