StopTech BBK Replacement Aero Rotor - Slotted 380x35mm - Left

The Emotive Secret Menu for Internal Combustion Engined Cars.

Hi fellow E9X M3 owner (and others!). This is a slotted left rotor ring for your 380x35mm StopTech ST-60 or STR-60 BBK. You need the right rotor ring as well if you want the set. I will assume if you are ordering this by part number (31.846.1101.99), you know exactly what you are getting. Known to be out of stock with a couple weeks of lead time. Order ahead to have spares on hand.
