Every rotor ring is poured from proprietary cast iron in-house, and every hat is machined from domestically sourced 6061-T6 aluminum. GiroDisc products are trusted on street cars, track day cars, and professional racing programs across North America and Europe. The company's engineering focus is simple: reduce unsprung weight, improve thermal capacity, and maintain the consistent pedal feel that drivers depend on when braking hard lap after lap.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eWhat is the GiroDisc A2-013?\u003c\/strong\u003e\n\u003cp\u003eThe GiroDisc A2-013 is a pair of two-piece fully-floating slotted rear brake rotors designed for 2003-2009 Nissan 350Z models equipped with factory Brembo rear calipers. They feature a 6061-T6 aluminum hat, GiroDisc proprietary cast iron rotor rings, and a 10-pin floating mount system, all manufactured in the USA.\u003c\/p\u003e\n\n\u003cstrong\u003eDo the GiroDisc A2-013 rotors work with stock Brembo calipers?\u003c\/strong\u003e\n\u003cp\u003eYes. The GIRA2-013 is designed as a direct bolt-on replacement for the factory Brembo rear rotor and caliper combination found on the 2003-2009 Nissan 350Z. No modifications to the caliper, bracket, or hub are required.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat 350Z trims came with Brembo rear calipers?\u003c\/strong\u003e\n\u003cp\u003eThe Brembo brake package was standard on the 350Z Track trim and available on the 350Z Touring. Verify that your specific vehicle has the larger Brembo rear calipers before ordering. Standard non-Brembo 350Z rear rotors use a different part number.\u003c\/p\u003e\n\n\u003cstrong\u003eWhy choose a two-piece floating rotor over a standard one-piece rotor?\u003c\/strong\u003e\n\u003cp\u003eTwo-piece floating rotors reduce unsprung weight at the corner, which improves suspension response and handling feedback. The float between the hat and rotor ring allows thermal expansion under heavy braking without warping, and the aluminum hat dissipates heat faster than a full iron disc, lowering rotor temperatures on repeated hard stops.\u003c\/p\u003e\n\n\u003cstrong\u003eDo the GiroDisc A2-013 rotors make noise when cold?\u003c\/strong\u003e\n\u003cp\u003eGiroDisc fits all drive pins with anti-noise spring washers on the rotor side. These washers keep light pressure on the ring at ambient temperature to eliminate cold rattle, while still allowing the ring to float freely at operating temperature when thermal expansion takes over.\u003c\/p\u003e\n\n\u003cstrong\u003eAre the GiroDisc A2-013 rotors legal for track day events?\u003c\/strong\u003e\n\u003cp\u003eYes. GiroDisc two-piece rotors are widely accepted at HPDE and track day events. The A2-013 meets or exceeds OEM dimensions, uses a recognized slotted finish, and does not require any modifications that would raise safety concerns. Always confirm specific event rules with your track day organizer.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat brake pads work best with the A2-013?\u003c\/strong\u003e\n\u003cp\u003eThe A2-013 rotor rings are compatible with any brake pad compound approved for use with OEM 350Z Brembo rear calipers. For street and occasional track use, a high-performance street pad works well. For dedicated track use, a race compound with a higher operating temperature range is recommended to match the thermal capacity of the two-piece rotor system.\u003c\/p\u003e\n\n\u003cstrong\u003eHow do I bed in GiroDisc A2-013 rotors?\u003c\/strong\u003e\n\u003cp\u003eGiroDisc recommends a standard bedding procedure: perform 8 to 10 progressively harder stops from approximately 60 mph down to 10 mph, allowing the brakes to cool between each stop. Avoid coming to a complete stop while the rotors are hot during bedding. After bedding, allow the system to fully cool before resuming normal driving.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eSafely lift the vehicle and support it on jack stands.
