GiroDisc 355mm Replacement Rings 2004-2017 Cadillac CTS-V, Chevrolet Camaro, SS, Dodge Viper TA 2.0

GiroDisc slotted replacement rings for the 2004-2017 Cadillac CTS-V, Chevrolet Camaro, SS, Dodge Viper TA 2.0 and the factory race cars listed below. When the iron on your 2-piece rotors wears out, these rings bolt back onto your existing Brembo or StopTech hats, so you replace only the part that wears. It is the most cost-effective way to keep a track car stopping well over many seasons.

How the rings work

A 2-piece rotor splits into an iron ring that wears and an aluminum hat that does not. These rings are GiroDisc's own cast iron with curved internal vanes that pump cooling air through the disc, and a slotted face that keeps the pad surface fresh. They mount to your existing Brembo or StopTech hats with floating drive pins, so the ring can grow with heat and center itself between the pads.

GiroDisc makes these rings as a direct swap for the iron on Brembo and StopTech 2-piece rotors of the listed size, so you can keep the hats you already run.

When to replace them

Swap the rings when they reach minimum thickness, or sooner if a crack reaches the outer edge of the ring. Bed in new pads with the new rings for the best pedal feel. Reusing the hats saves weight and money every time the iron is due.

What's Included

Two slotted iron rings. New drive pin hardware is also supplied. Hats are not included: you reuse your existing Brembo or StopTech hats.
