That can't be right either. In that case how do you explain the value of carbon ceramic disks?This has always made me laugh in no way does the power of a car have any effect on the strength of the brakes.There are always these if it wasn't for the 'not for more than 200 bhp' warning: http://www.elisepart...elled-discs-s2/
Yes it could mean it would be going faster between corners but that would be a heat dissipation issue, retarding force is defined by the pads and tyres not how fast your going.
You can lock up a wheel with your normal disks, so it's not that carbon brakes harder. However, on carbon disks you can brake a lot later (even when steel brakes not yet getting too hot).
Retarding force is definitely also determined by the disk surface..
