I would agree with that.
There is something to be said about more pistons, and the stiffness of the caliper as well as in relation to the car weight and grip of the tires.
A lot of things play a big role in how the brakes work on a race car.
Heck you can throw race pads in your stock brakes and get the car to stop just as hard as the race car does once or twice. Aftermarket calipers, rotors, hats.....their main role is repeatability. If the driver knows he can hit the 100 foot brake point each time for an hour, then he is confident in what the car can do and when it can stop...and will be faster than if he has no idea how it is going to stop and when.
If we were talking a 1967 Camaro with drum brakes or 10" rotors and single piston calipers vs installing a 14" 6 piston caliper kit then it would be a bigger change however with modern braking systems today going to a BBK is just about making sure that car will stop every single time just like it did the first time around.
