FAQs – Alfa Giulia / Stelvio Quadrifoglio Front Rotors Will these work with stock Brembo calipers? Yes — they’re designed to mount directly to the factory calipers without needing spacers or adapters. Can I use these rotors for spirited street driving and occasional track days? Absolutely — Girodisc rotors balance track-level performance with street reliability. Do they produce any noise or vibration? The anti-noise spring washers prevent rattle and vibration while still permitting natural thermal expansion. When should I replace the iron rings? Once the rings reach their minimum thickness specification (as per Girodisc guidelines) or show cracking, they should be replaced to maintain safe performance.
