Re: Looks like I need to replace my rotors and pads
F1 - invalid argument - they use carbon fibre composite not steel.
Science is the key - the engineering required to have the correct sized hole, shape of the hole, location of the holes etc takes time and is costly. Your average Joe would rather pay less for something that has a "cool" pattern drilled into them because its cheap.
The picture in the article you posted - after having a close look that rotor is excessively worn. When you compare the edge of the rotor to the pad swept area there is a big difference. That rotor IMO was well beyond its useful life.
Holes should only be in a vented rotor - never solid.
Holes should never be drilled they should CNC milled
Holes should never have a 90 corner(stress riser) the should have a bevel and radii - hence the CNC milling
Holes should cover the entire area that is swept by the pad
IMO rotors with holes are a great choice IF you buy from the right manufacture. $69.00 eBay drilled rotors will give you $69.00 performance. Brakes are not some place to be cheap on.
