I jumped on the Feets bandwagon with the AMG stuff.... 14.25" rotors, and recently went from the 4 piston Brembo's I had to the 8 piston ones. Course it's only on a smaller little Holden Torana.

(this was at mockup, going to be painting the calipers red to match the rears I figure.)

Handy that the 8 piston and 4 piston calipers both use the same mounting pattern. Just a couple minute swap between the 2 of them.
