What makes the Brembo GT|R different from the GT and GT|S systems for the 2024 Tesla Model S?

The GT|R uses a CNC billet aluminum caliper body instead of the cast aluminum construction found in the GT and GT|S. It also features ventilated stainless steel piston inserts, recessed dust boots, and a nickel-plated finish for maximum corrosion resistance. Brembo classifies the GT|R as a race-specification caliper that retains Road Car Caliper validation; no noise or comfort trade-offs typically associated with race systems.

What vehicles does the Brembo GT|R Big Brake Kit 1N-.9547A fit?

The Brembo GT|R Big Brake Kit fits the 2024 Tesla Model S with radial mount front calipers and the 2024 Tesla Model S Plaid. This is a front axle kit. Confirm your vehicle's caliper mount type before ordering, as this kit is specific to the radial mount configuration.

What rotor size does the Brembo GT|R Big Brake Kit use on the 2024 Tesla Model S?

The Brembo GT|R Big Brake Kit uses 405mm two-piece rotors. Each disc assembly combines an advanced high-carbon alloy iron disc with corrosion-resistant plating and a CNC-machined aluminum hat, connected via a floating H-Bobbin system with an anti-rattle spring.

Does the Brembo GT|R Big Brake Kit for the 2024 Tesla Model S come pre-assembled?

Yes. The Brembo GT|R Big Brake Kit ships as a complete, pre-assembled front axle set. Brembo stainless steel braided brake lines by Goodridge, CNC billet caliper adapters, and all necessary installation hardware and fasteners are included.

What brake pads are included with the Brembo GT|R system for the 2024 Tesla Model S?

The Brembo GT|R system includes Ferodo FM1000 compound pads. The FM1000 is a proprietary friction material supplied exclusively to Brembo, offering strong initial response, precise feel, and consistent modulation across street and track environments. Pad volume is 107.3 and surface area is 95.4.

What finish is available on the Brembo GT|R Big Brake Kit for the Tesla Model S?

The Brembo GT|R Big Brake Kit for the 2024 Tesla Model S is available in Nickel Plated only, with a machined Brembo Racing red logo. The nickel plating provides corrosion resistance suited for both track and daily street use. It is available across all three rotor configurations; Cross Drilled, Type 1 Slotted, and Type 3 Slotted.

Description

Brembo Front Big Brake Kit (GT|R System) for MS Tesla Model S / Plaid

The Brembo GT|R Big Brake Kit for the Tesla Model S and Model S Plaid is the top tier of the GT system lineup; a race-specification brake kit that retains full streetability. Where the GT and GT|S use cast aluminum caliper bodies, the GT|R steps up to CNC billet monobloc construction with nickel plating and ventilated stainless steel piston inserts. The result is a caliper with the strength and corrosion resistance of a purpose-built race component, none of the noise or comfort penalties typically associated with a race system, and Brembo’s validation as a Road Car Caliper. It ships as a complete, pre-assembled front axle kit with all necessary hardware included.

GT|R Billet Monobloc Caliper

The GT|R uses a CNC billet aluminum 6-piston monobloc Brembo caliper in a radial mount configuration. Billet construction delivers greater structural rigidity than cast aluminum, and the nickel plating adds corrosion resistance suited for both sustained track use and everyday driving. Ventilated stainless steel piston inserts and recessed dust boots round out a caliper built to handle extreme heat without compromising seal integrity or pedal feel. Available in Nickel Plated only with a machined Brembo Racing red logo.

Rotor Options: Cross Drilled, Type 1, and Type 3

All three rotor configurations share the same base specifications. Outer diameter is 405mm, annulus is 62mm, width is 34mm, and air gap is 12mm. Each disc assembly uses a two-piece construction: an advanced high-carbon alloy iron disc with corrosion-resistant plating mated to a CNC-machined aluminum hat. The disc-to-hat connection uses a floating H-Bobbin system with an anti-rattle spring.
Cross Drilled rotors are the street and mild track choice, offering the highest initial bite of the three options. They perform well in wet conditions and continuously refresh the braking surface, though they are more prone to thermal cracking under sustained race-level heat. Type 1 Straight Slotted rotors use Brembo’s 8-straight-slot face pattern and are the better fit for drivers who push harder and longer on track. This configuration prioritizes stable brake feel and thermal resilience, with low disc wear and consistent surface renewal. Initial bite is lower than the drilled and Type 3 options. Type 3 Motorsport Slotted rotors are built for competition, with an emphasis on maximum initial response and a smooth pedal release. Less time on the brake pedal typically means faster laps; this is the rotor for drivers focused on that outcome. The trade-off is a higher rate of pad and disc wear due to the aggressive face pattern.

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.
