I found a vendor on eBay that offers slotted and drilled rotors for just $25 or so over the price of standard rotors, this is for the complete set of rotors and semi-metallic pads for both the front and rear axles. The cost-up also includes nickle plating that I hope will keep the rust at bay. The rotors LOOK really good, how they perform is yet to be seen. I'm not really a speed demon, but I like stuff that looks good -- assuming it works good too, which is really the more important quality of stuff.
I decided that if slotted and drilled rotors are good enough for an M3, they should be good enough for my '94 convertible. My Bentley manual states that the the slotted rotors are directional, but does not describe which rotor goes on which side.
My instinct is that the slots and holes should slant toward the rear as I am looking at the top half of the rotor. Does anybody dispute that, and why?
Thanks,
