Girodisc 380x35mm 10 Pin Holes 52mm Annulus Slotted Rings Porsche 911 GT3 (2014-2019)

Girodisc 380x35mm slotted rings deliver track-proven braking for 2014-2019 Porsche 911 GT3 and GT3 RS front axles. These two-piece rotor rings feature 10 pin holes and 52mm annulus for secure mounting to aluminum hats. They cut unsprung weight while boosting heat dissipation and pad bite during aggressive driving.

Key Features

  • Slotted Surface: Narrow slots wipe gases and debris for consistent friction and shorter stopping distances in wet or track conditions.
  • Curved Vanes: Internal directional vanes pull cool air through for rapid heat rejection during repeated hard stops.
  • Lightweight Design: Each ring weighs 24.2 lbs versus OEM 29.5 lbs reducing rotational inertia and improving handling response.
  • High-Carbon Alloy: Resists thermal cracking and warping under extreme loads for long service life.
  • Precision Specs: 380mm diameter 35mm thick with 10 stainless pins ensure perfect OEM fit and balance.

Product Notes

  • Pair of rings requires compatible aluminum hats sold separately.
  • Clean with brake cleaner avoid harsh chemicals to maintain finish.
  • Freight shipping for heavy items oversize box applies.

Installation Notes

  • Professional installation recommended.
  • Torque pins to 25 ft-lbs using Girodisc specified thread locker.
  • Compatible with Girodisc hats OEM calipers and pads.
