Stoptech Performance Slotted Front and Rear Brake Rotors
Fits 2005-2007 Subaru Impreza WRX STI 2.5L

This is a complete set of four rotors for the '05-'07 Impreza WRX STI.
This does not fit the WRX.

Excessive heat can cause resins in your brake pad to vaporize or “outgas.” As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here’s where StopTech SportStop slotted brake rotors make a big difference. StopTech SportStop Slotted Brake Rotors for the 2005, 2006, 2007 Subaru Impreza WRX STI 2.5L are a true performance rotor and feature:

– Engineered Performance Rotor

– Superior resistance to cracking due to thermal stress 

– Increased molybdenum (higher carbon) content that extends reliability, service life and helps reduce NVH “noise” issues 

– Rotor material is a direct descendant of the patented AeroRotor from StopTech

Introducing directional curve vane design (on select applications)

– Improved vane design or OE equivalent on all rotors

– Center split castings

New short slot design runs perpendicular to the vane to preserve rotor strength.

Direct OE Replacement

Improved wet weather response

Increased initial “bite”

Double disc ground for a consistent friction surface and Improved pad bed-in

Mill balanced

Black E-Coated non-friction surfaces on “Power Alloy” rotors

Enhances open wheel appearance


Front Rotor Size: 326mm x 30mm
