GiroDisc 2-Piece Brake Rotors — Canada
Priced in CAD • No duties • No brokerage fees • Fast shipping across Canada
GiroDisc is an American manufacturer of 2-piece floating brake rotors — their aluminum hat and iron ring design allows the rotor ring to expand freely under heat without warping or cracking, addressing the primary failure mode of one-piece rotors under sustained track use. GiroDisc rotors are a direct-fit upgrade for vehicles using OEM-size rotor dimensions, with aluminum hats in various finishes. At MyPartsGuy.ca we carry the GiroDisc lineup, all priced in Canadian dollars with no import fees or brokerage charges.
For Canadian track day enthusiasts who have experienced rotor warping after sustained hard use — particularly on heavier vehicles or at longer track sessions — 2-piece floating rotor designs like GiroDisc address the problem at a fundamental engineering level rather than simply using a thicker one-piece rotor.

Frequently Asked Questions
Why does a 2-piece rotor not warp like a 1-piece?
Conventional one-piece rotors warp when uneven thermal expansion causes the iron ring to deform — the hat and ring expand at different rates but are rigidly connected, so stress builds in the ring. In a 2-piece floating design, the iron ring is connected to the aluminum hat via bobbins (drive pins) that allow the ring to float — thermal expansion occurs freely without stress concentration, preventing the warping cycle that plagues one-piece rotors under sustained track heat.
Can GiroDisc rotors be resurfaced?
Yes — the iron ring can be resurfaced when worn. The aluminum hat is reusable; only the ring wears. This long-term serviceability makes 2-piece rotors a cost-effective investment for drivers who track regularly, as hat replacement is not needed between ring changes.
