Brembo Front UPGRADE GT 2-Piece Drilled Discs for 99x Porsche 911 Carrera, C4, C4 GTS, C4S, GTS, S, T / Turbo

The Brembo UPGRADE GT 2-Piece Drilled Front Discs provide a significant performance enhancement for select 996, 997, 991.2, and 992 Porsche 911 models by replacing the factory one-piece rotors with a lightweight, track-proven two-piece design. Each rotor features a high-carbon iron outer disc mated to a precision-machined aluminum hat via a floating D-bobbin system with anti-rattle springs — improving heat dissipation, reducing unsprung weight, and allowing for greater thermal stability under repeated hard braking. The drilled, curved vane vented design enhances cooling efficiency and initial bite, while the corrosion-resistant plating ensures long-term durability. Engineered as a direct OE replacement, these 330mm x 34mm discs are fully compatible with factory calipers and retain full street drivability while offering track-day performance for drivers seeking sharper response and improved pad wear control — without the compromises of a full racing setup.

Drilled Disc (D)

These two-piece floating brake rotors feature precision-drilled holes that lower unsprung mass and quickly release heat under load. The result is a visually striking design paired with powerful, consistent braking performance in all driving conditions.

UPGRADE GT Systems

Brembo’s UPGRADE GT Systems deliver a complete, vehicle‑specific braking solution engineered to work seamlessly with the factory master cylinder and ABS for unmatched balance, performance, and safety. Each kit is designed by Brembo for optimal hydraulic compatibility and braking distribution, ensuring confident pedal feel and consistent stopping power in both street and track environments. Offering a significant step above OE performance, UPGRADE GT Systems provide improved heat management, fade resistance, and durability without compromising everyday drivability.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
