Review GIRODISC Compatible With/replacement For Porsche Turbo/turbos 991 Excl fits TURBO 911

Introducing the Girodisc A2-155, a high-performance brake disc upgrade designed specifically for the Porsche 911 Turbo (991 Turbo and Turbo S) models. The Girodisc A2-155 is not just a replacement disc, but a significant upgrade for your high-performance sports car.

The Girodisc A2-155 is engineered to provide superior strength and durability compared to the original Porsche discs. It is made from an aerospace-grade billet aluminum alloy, which is lighter and stronger than the cast iron OEM discs. This reduces unsprung weight, contributing to improved handling and quicker response times.

The disc features a unique venting design, which provides efficient cooling during high-speed driving and aggressive track use. The venting design also helps reduce the risk of brake fade, ensuring consistent performance throughout your drive.

The Girodisc A2-155 also comes with an optional high-carbon, floating iron disc, which provides even more heat dissipation and durability compared to the aluminum disc alone. This option is ideal for track use or for those who frequently drive their Porsche 911 Turbo at high speeds.

The Girodisc A2-155 is also compatible with most aftermarket brake pad compounds, allowing you to customize your brake setup for your specific driving needs. The discs come pre-slotted for most popular drilled and slotted rotor patterns, ensuring a seamless installation process.

With its superior strength, durability, and cooling capabilities, the Girodisc A2-155 offers a significant upgrade to the stock brake system on your Porsche 911 Turbo. It is the perfect choice for those who demand the best in performance and reliability from their high-performance sports car.
