Used, good condition front and rear rotor set for M3P. Racking Brake brand, OE size replacements. Front and rears are slotted, fronts are also vented. These retail for ~$2100 new. Asking $1200 OBO plus shipping, or local pickup in Phoenix.
The XT970s are down to 50% because they glazed over and I sanded the glazing off, twice. That is not reflective of rotor wear. These rotors have only seen 4 track days. I'll try to find minimum thickness info.
