I just bought some Girodisc rotors through Shaun at AED so when i went to the free Friday practice today i had a keen interest in the braking systems. Some observations
1. some guys actually had a custom backing plate that allowed two unique 3" air inlet hoses to flood the inside turbine section of the rotor.
2. All fronts are two piece free floating rotors / hats. but they seem to have different designs.
3. Most of the rear rotors are free floating but not all.
4. Some rear rotors are factory 9" diameter some with the new 13"
5. Pit crew can change front brake pads in 2min. wow.
6. Never saw any ducted silicone hose cooling on the rear brakes.
7. everyone was using the factory two piston rear caliper.. no exceptions.
8. several brands of pure race front calipers were used, AP, Brembo, brands i have never heard of.
9. saw some teams using titanium pad to piston heat insulating spacers, others what looked like kevlar or ceramic, others still no insulators.
10. noticed some cross drilled, others slotted, some just plain surface.
11. the billet race only calipers could been seen in 4 or six piston guise, and those pistons make the factory brembo calipers look cheap!
12. mustangs were braking toe to toe with R8, Porsche, and anyone else out there.
Here are some pics, thoughts appreciated.
