These are the compounds we stock for the Brembo OE 4-pot — EVO / WRX STI / GT-R / VF Redline whose published friction and operating temperature come closest to Circo S83. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
