Girodisc D1-023 McLaren 380mm Front Ring FAQs
Can these be installed with factory McLaren rotor hats? No. The D1-023 rings are designed exclusively for Girodisc aluminum hats and are not compatible with OEM carbon-ceramic or iron rotors.
Do these rings improve braking compared to OEM steel rotors? Yes. The floating two-piece design improves heat dissipation, reduces unsprung mass, and enhances braking consistency under heavy load.
What brake pads pair best with these rotors? For street and occasional track driving, Ferodo DS2500 or Hawk HPS 5.0 offer excellent balance. For dedicated track use, Pagid RS29 or Carbotech XP12 pads provide high-temperature stability and fade resistance.
What torque should I use for installation hardware? Torque all fasteners to 12 ft-lbs (16 Nm) with blue Loctite. After one full heat cycle, recheck torque to confirm proper float and secure alignment.
