And yes, I did misread the "blank" floating rotor part. In response, I will post a picture of Performance Friction's really cool floating and dimpled rotors that they use on the Formula 1 C63 safety cars. Directionally vented, dimples with a nice radius, a special mounting setup that puts the top at bolts in double shear, and then there is the fact that they are like huge 15" rotors.

Yea I should've been more specific. I think we're generally in agreement though

And those brakes are beautiful Makes the CSL brakes I'll be mounting next week look tiny
