Upgrade Your Subaru's Stopping Power with Girodisc A2-185 Rotors
Are you ready to enhance the braking performance of your 2018-2021 Subaru WRX or STI? The Girodisc A2-185 rotors are designed specifically for your vehicle, offering a direct replacement for the factory discs without any modifications required. This means you can easily bolt them on and enjoy improved performance with your OE calipers.
Why Choose Girodisc A2-185 Rotors?
When it comes to braking upgrades, the Girodisc A2-185 offers a lightweight, high-performance alternative to bulky big brake kits. By maintaining your factory brake bias and ABS efficiency, these rotors ensure that you get faster acceleration and better suspension response thanks to reduced rotational and unsprung weight.
Top-Notch Materials and Design
The A2-185 rotors are crafted with precision from U.S.-sourced 6061-T6 aircraft-grade aluminum for the central hat section. The rotors themselves are made from Girodisc's proprietary cast iron, poured and machined in-house in the USA. Their innovative curved vane design, developed from racing technology, acts like a centrifugal pump, effectively channeling cooling air through the disc to maintain optimal performance.
Floating Mount System for Superior Performance
The Girodisc A2-185 features a floating mount system that utilizes 10 high-strength alloy steel drive pins, engineered to Girodisc's specifications and cadmium plated for long-lasting corrosion resistance. This system allows the rotor to float axially and radially, ensuring it self-centers between the brake pads for consistent contact and performance. Plus, the anti-noise spring washers eliminate unwanted rattle and noise when the rotors are cold, providing a quiet ride without compromising performance.
