Stoptech question

bmwfst1 · 04-01-2024, 09:03 AM

I have a stoptech 380mm big brake kit on the front of my M3. I need replacement rotor rings. There are 4 rotor thickness options available. 28,32,34,35 mm. Which one is the correct one?

If its a 380mm ST60 kit (388 doesnt exist as far as I know) then you need 380x35mm rings. Girodisc makes very nice replacement rings. If you need a set feel free to DM me
