A1-318 GiroDisc 2pc GiroDisc Cadillac CT4-V Blackwing Front Rotors If you’ve pushed your CT4-V Blackwing hard enough to earn the respect of your local track crew—or maybe the stink eye from your tire guy—then it’s time to upgrade your stopping power. The GiroDisc A1-318 2-piece front rotor set isn’t just another performance part; it’s a surgical tool for braking precision, tailored for one of Cadillac’s most track-ready sedans. Features That Deliver More Than Just a Shorter Stopping Distance: Two-Piece Floating Rotor Design: Reduces unsprung weight and improves handling feel without compromising strength. Lighter rotors mean quicker turn-in and less rotational mass to fight against under hard braking. High-Carbon Alloy Rotor Rings: Superior heat dissipation and resistance to cracking under repeated heat cycles—ideal for high-performance driving or track days where stock rotors just don’t cut it. Direct Bolt-On Fitment: No guesswork, no fabrication. These rotors are made to work with your stock calipers and fit your CT4-V Blackwing like a glove. Installation is a breeze, which means more time driving, less time wrenching. Rebuildable Design: When your rotor rings are worn down, you don’t toss the whole unit—just replace the rings. It’s better for your wallet and better for the planet. Technical Specifications: Application: 2022+ Cadillac CT4-V Blackwing (with optional Track Performance Package or factory iron rotors) Rotor Diameter: 14.96 in (380mm) Construction: 2-piece floating rotor, aluminum hat Material: High-carbon cast iron rotors, 6061-T6 aluminum hats Weight Savings: Approx. 4-6 lbs per rotor vs OEM Mounting: Direct bolt-on GiroDisc Cadillac CT4-V Blackwing 2pc Front Rotors FAQs Are these rotors a direct fit for my CT4-V Blackwing? Yes, they’re designed specifically for the factory brake setup. No modifications needed. Can I use these rotors for both daily driving and track days? Absolutely. These rotors shine on track but stay composed during daily stop-and-go driving. How do GiroDisc rotors compare to OEM or other aftermarket options? GiroDisc rotors are lighter, stronger, and rebuildable—offering real performance and long-term value that most OEM and many aftermarket options can’t match. What’s the expected lifespan of these rotors? Lifespan varies based on use, but the modular design allows you to replace just the rotor rings, extending overall service life significantly. Do I need special brake pads for these? While they work with most performance pads, GiroDisc recommends high-friction, track-capable compounds to get the most out of your setup. For drivers who take performance seriously, stopping isn’t just something you do — it’s something you master. With GiroDisc rotors under your CT4-V Blackwing, you’ll stop harder, later, and more consistently, lap after lap. Upgrade today and feel the difference where it matters most—under your right foot.

A1-153 Girodisc 2pc Front Brake Rotors FITMENT: Porsche Boxster S and Cayman S (981), Front This Girodisc system is an upgrade from Porsche's 330mm one-piece OEM front rotors to 350mm two-piece floating steel rotors with aluminum hats, a direct replacement for the OEM brake disc. The two-piece floating disc will bolt directly to the car and work with your OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. Girodisc two-piece floating rotors are lighter than OEM brake rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response. When used with Pagid or PFC performance brake pads, and RF-1 brake fluid (available from ), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat mount together through a floating mount system which utilizes ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by Grade-12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The two-piece Girodisc design allows for disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance. Sold/priced per pair.
