Product details
Select a front or rear GiroDisc rotor pair for an iron-braked 718 Cayman GT4 RS. The two-piece assemblies let the friction rings be replaced later while the matching hats are retained. Spyder RS coverage is listed by Fabspeed but needs an exact axle-reference confirmation before ordering.
Before you order
For a Spyder RS, confirm the exact GiroDisc front or rear reference against your original iron-brake package before ordering. PCCB cars require separate conversion references.
Technical Details
- Sold and priced as one axle pair; choose Front or Rear.
- Two-piece floating design with reusable aluminum hats and replaceable iron friction rings.
- 6061-T6 aluminum hats and curved-vane cast-iron rings.
- Floating hardware allows heat expansion while spring elements control cold rattle.
- Designed around the matching original iron-brake configuration; retains appropriate factory calipers and pad arrangement.
- PCCB conversions require separate rotor references and are not included by this application.
- The GT4 RS front configuration uses 408 × 36 mm rotors; GiroDisc specifies 34 mm as the front ring replacement limit.
- Front rings are the D1-291 service reference; confirm the rear ring separately.
