2-piece rotors, bolt + threaded hat, bolt+locknut or bolt+special nut?

[Humble]

Not to pry too deeply but are you working on a 2 piece rotor and brake setup for super's and/or standard bugs? I've been looking at off the shelf options using wilwood, 2 or 4 pot calipers and 2 piece 10.75" rotors.

As for brake rotor/hat assembly, the floating race setup is nice but not necessary for most applications. I'd go with the threaded hat or the stepped bobbin to keep things simpler.

My painter has Alcon floating brakes on factory made ex-Frank Biela race Audi 80, but he has also left two 330x32 fixed wilwood rotors and aluminum hats together with just bolts and all metal jet nuts from "super saloon" class 900kg Volvo PV with 250+hp, and they worked great at track. Car was race only, but not some 700hp track monster

If you havent seen what car i am talking:



Audi is different, it has huge factory racing brakes from Alcon, with floating hats, barely fits to 18" center locking wheels. Whole car looks like almost stock old audi 80, but looks can be deceiving..carbon fibre fenders, hood, doors, nothing left from stock suspension etc.






I think i go with stepped nuts from cromoly and 12.9 capscrews, wonder if these materials like electric zinc coating?
