D2-318 Girodisc Cadillac Rear Replacement Rings FAQs

What’s the recommended minimum thickness? Replace rear rings at 26 mm or sooner if any crack reaches the outer edge.

Do I need to re-bed pads? Yes — re-bed after ring installation for optimal friction transfer.

Can I mix these with OE front rotors? Yes, but best results come from matching front and rear Girodisc assemblies.

Hardware reuse? Use the supplied new hardware; do not reuse worn pins/springs.
