GiroDisc Brake Rotor Upgrade for Porsche 997 GT3 / GT3 RS

Match the early 997 GT3 rotor upgrade to the axle and original iron or PCCB brakes. Required caliper spacers must be matched to the specific enlarged assembly, not assumed identical at every corner.

Technical Details

• Fabspeed catalog reference: FS.POR.997GT3.XBRXX. The selected option determines the complete supplied configuration.
• One pair of complete rotors for the selected axle; order front and rear pairs for all four corners.
• Floating two-piece construction with aluminum hats and curved-vane iron rings.
• Replacement friction rings must match the exact GiroDisc hat/reference.
• Confirm rotor diameter, thickness, offset, pad shape and wheel clearance against the supplied part number.
• Carbon-ceramic conversions require suitable iron-rotor pads and a coordinated four-wheel specification; pads are not implied as included.
• Fabspeed lists caliper spacers for the enlarged rotor application; confirm exact hardware included with the selected pair.
