Rings, not a full disc

A track-driven Blackwing eats friction surface long before it wears out a hat. These replacement rings put a fresh slotted face back on the car at a fraction of the cost of complete two-piece discs. Change them in axle pairs.

Fitment

2021 and newer Cadillac CT4-V Blackwing, rear. The source data does not list ring dimensions, so confirm fitment by year, trim, and brake package before ordering.

Installation notes

Inspect the hats and the ring-to-hat hardware while the assembly is apart and replace anything worn. Bed the fresh rings with progressively harder stops so the pad lays an even transfer layer before the next track session.

Ordering

Sold to the listed part number. Match it to your existing GiroDisc hats before ordering.
