Hey man, I sent you an email about the 5mm and 2mm Rotor Spacers. I'd love to know if it's still possible to get them, or if there is something else I can use instead of them.
If you look up 3mm brake rotor spacer you will find them. They are universal. I would recommend getting one that is about 3mm. Then getting a pack of like 0.5mms so you can adjust if needed
