2022-2026+ BMW I4 (G26) Carbon Ceramic Big Brake Kit — Brembo GT6 6-Piston Bentley Both the ZL1 and SS

Both the ZL1 and SS use 4-piston-or-larger front calipers

Honestly: a cold carbon-ceramic disc naturally bites a little less than cold iron on the first stop — that's physics

The 430mm Ultra front disc and 414mm Max front disc are large

This adds real rear thermal capacity so the front isn't doing all the work under sustained heat

so on this kit winter cold-car feel comes very close to summer feel
