Machined and assembled entirely at GiroDisc's facility in Bellingham, Washington, the A1-013 replaces the OEM single-piece iron disc with a premium two-piece assembly that reduces unsprung and rotational mass, dramatically improves thermal management, and keeps pedal feel sharp under repeated hard stops. If your 350Z runs the Brembo caliper setup and you push it on track days, canyon roads, or spirited driving, the A1-013 is the rotor upgrade built to handle that demand.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDirect bolt-on replacement for factory front rotors on 2003-2009 Nissan 350Z with OEM Brembo four-piston calipers\u003c\/li\u003e\n\u003cli\u003eTwo-piece floating rotor construction: 6061-T6 aircraft-grade aluminum hat paired with GiroDisc proprietary high-carbon cast iron ring\u003c\/li\u003e\n\u003cli\u003eCurved-vane internal cooling channels act as a centrifugal pump, pulling cool air through the rotor under load\u003c\/li\u003e\n\u003cli\u003eFully floating mount system with 10 cadmium-plated high-strength alloy steel drive pins for controlled thermal expansion\u003c\/li\u003e\n\u003cli\u003eBelleville washers and anti-noise spring clips eliminate rattle while maintaining float\u003c\/li\u003e\n\u003cli\u003eSlotted ring face for continuous pad degassing and swept contact area\u003c\/li\u003e\n\u003cli\u003eFully rebuildable: replace the iron rings only when worn and reuse the aluminum hat and hardware\u003c\/li\u003e\n\u003cli\u003eMade in the USA from domestically sourced materials\u003c\/li\u003e\n\u003cli\u003eMaintains factory brake bias and ABS calibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2003-2009\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e350Z\u003c\/td\u003e\n\u003ctd\u003eTouring (w\/Brembo Calipers)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2003-2009\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e350Z\u003c\/td\u003e\n\u003ctd\u003eTrack (w\/Brembo Calipers)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2003-2009\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e350Z\u003c\/td\u003e\n\u003ctd\u003eEnthusiast (w\/Brembo Calipers)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e The A1-013 fits only 350Z trims equipped with the factory Brembo four-piston front caliper.

Every A1-013 is poured, machined, and assembled in-house using U.S.-sourced cast iron and aerospace-grade aluminum. GiroDisc's two-piece floating design has become the benchmark for high-performance OEM replacement rotors, trusted by track day drivers and performance enthusiasts who want race-proven thermal management without sacrificing street drivability. The rebuildable design means customers replace only the iron ring when it wears out, reusing the hat and hardware to minimize long-term maintenance costs.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eWill the GiroDisc A1-013 fit my 2007 Nissan 350Z Touring with Brembo calipers?\u003c\/strong\u003e\n\u003cp\u003eYes. The A1-013 is a direct bolt-on replacement for all 2003-2009 Nissan 350Z models equipped with the factory Brembo four-piston front caliper package. No modifications or adapters are required.\u003c\/p\u003e\n\n\u003cstrong\u003eHow do I know if my 350Z has Brembo calipers?\u003c\/strong\u003e\n\u003cp\u003eLook through the front wheel at the caliper body. Brembo calipers are typically red with the Brembo script cast into the housing and feature four distinct pistons. The Touring, Track, and Enthusiast trims most commonly received the Brembo brake package, though availability varied by year and region.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I use my existing brake pads with the GiroDisc A1-013?\u003c\/strong\u003e\n\u003cp\u003eYes. The A1-013 is dimensionally equivalent to the OEM front rotor and works with pads designed for the factory Brembo caliper. No pad modifications or new hardware are required for installation.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the difference between the GiroDisc A1-013 and a standard one-piece replacement rotor?\u003c\/strong\u003e\n\u003cp\u003eThe A1-013 uses a two-piece floating design that separates the iron ring from the aluminum hat. This allows the ring to expand thermally without warping, improves cooling through the curved-vane air pump system, and reduces overall unsprung weight compared to a solid one-piece rotor. The result is more consistent pedal feel under repeated hard stops and longer rotor life on track.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat does the slotted pattern on the A1-013 do?\u003c\/strong\u003e\n\u003cp\u003eThe slotted face continuously sweeps away brake dust and outgasses heat from the pad surface during braking. This prevents glazing and maintains consistent bite across a wide temperature range, which is especially important when transitioning between street and track use.\u003c\/p\u003e\n\n\u003cstrong\u003eHow do I bed in the GiroDisc A1-013 after installation?\u003c\/strong\u003e\n\u003cp\u003ePerform a series of moderate stops from 40-50 mph, allowing the rotor to cool between each stop. Follow with a series of harder stops from 60 mph. Avoid coming to a complete standstill with hot rotors for the first several hundred miles. Full break-in typically takes 200-300 miles of varied driving.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I replace just the iron rings when they wear out?\u003c\/strong\u003e\n\u003cp\u003eYes. GiroDisc rotors are fully rebuildable. When the rings reach the minimum thickness of 28mm or develop cracking that reaches the outer edge, you can order replacement rings separately and reuse the aluminum hat and all floating hardware, significantly reducing long-term maintenance cost.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the GiroDisc A1-013 street-legal and quiet enough for daily driving?\u003c\/strong\u003e\n\u003cp\u003eYes. The anti-noise spring clips and Belleville washers control float while preventing the rattle typically associated with floating rotors. The A1-013 is used daily on street cars and offers a quiet, smooth pedal feel comparable to OEM rotors.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the GiroDisc A1-013 require any special tools for installation?\u003c\/strong\u003e\n\u003cp\u003eNo special tools are required. Standard hand tools and a torque wrench are sufficient. The rotor mounts using your factory hub hardware. Refer to GiroDisc's torque specifications for the drive pin cap screws during assembly if you are rebuilding rings.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eSafely raise and support the vehicle, then remove the front wheels.\u003c\/li\u003e\n\u003cli\u003eRemove the brake caliper and support it with a hanger or wire.
