I am going down a rabbit hole with the Type 3 Brembo 2-piece rotors 380x32 for my 2013 GT500 caliper swap on my 2013 Boss 302 LS and am hoping for a greater explanation of why I have been repeatedly told that Brembo Type 3 rotors/rings cannot utilize custom hats and work with the OEM '13-'14 GT500 calipers?
For example, if you purchase the rotor rings separately and make custom aluminum hats, I see no reason why this would not work; that said, I am not an engineer and not nearly as skilled with brakes as many on this forum
If the OEM ’13-’14 GT500 rotor is 14.96"x1.26" or 380mmx32mm
Rotor Outside Diameter (in.): 14.96" = 380mm
Brake Rotor Bolt Pattern (in.): 5x 4.50"
Brake Rotor Bolt Pattern (mm): 5x114.30mm or 5x4.50"
Nominal Thickness (in.): 1.260" = 32mm
and the Brembo Type 3 rotor/ring is also 380mmx32mm or 14.96"x1.26"
Why would you not be able to take a custom hat CNC cut to the same/similar specifications as the OEM replacement hat sold by Baer for their 2013-2014 GT500 Eradispeed OEM rotor swap but use the bolt pattern from the Brembos (10 in ring circle as opposed to 12)? Especially given multiple Brembo race setups utilize the 380mm rotor. Even if a larger width ring was selected, like 34mm, you could adjust the pads, and it would fit.
Baer Eradispeed Hat Specifications
Wheel Bolt pattern 1: 5 x 4.50" or 114.3mm
Wheel Bolt Hole Diameter: .625"
Baer Rotor Bolt Circle: 12 x 8.500" (Cut to match Brembo Type 3)
Rotor Bolt Hole Diameter: .257" Through hole (Cut to match Brembo Type 3)
Hat Center Bore: 2.796"
Hat Depth: 0.235" (Likely a further adjustment point - but maybe not)
Hat Face Thickness: .300"
Mount Style: Fixed or Floating (Custom McClaren Hardware)
Material: 6061 T6 Aluminum
Has anyone made custom hats? I know they are more common in the kit market (Factory Five, etc.) ,but hoping someone has insights or some glaring aspect I am overlooking.
I like the Girodisc rotors, and having spoken with them yesterday, I know some very nice developments are coming this summer for all S197s (especially 2013-2014 GT500s) to enjoy. However, I still am confused why the multiple vendors I contacted stated custom hats of the Brembo Type 3 rotor could not be done with the OEM caliper.
I could understand vendors saying Type 3's are ‘not recommended for primarily street,’ a ‘waste of my time or money to make it work,' or even ‘possible but look, we sell XYZ, which is easier/better' but to say ‘it cannot be done' is confusing if the only limitation I can see for fitment is making certain the hat is perfectly aligned to the OEM '13-'14 GT500 caliper.
Any and all help/guidance is appreciated.
