Perhaps I’ve been over thinking this (Proof I’ve been over thinking this:

I’ve got the flu, hence why I’m doing engineering equations on a Saturday night. I’m usually not this pathetic.)

I’m thinking of ordering the www.raceconcepts.net slotted and dimpled rotor, but after seeing this picture mcgyvr posted

of the rotors I’m worried that too much of the surface area of the rotors has been removed. The braking torque is directly proportional to the contact area between the brake pad and rotor. How much of the surface area has been removed I don’t know. Is it enough to make a difference? My car will never see track use so the slots and dimples are strictly cosmetic. I don’t want to decrease the stopping ability of my car for the sake of looks. The “cheese grater” effect of the slots that some people have talked about before will only be there for a short period of time because eventually the slot edges will become rounded.
