Where can you get slotted rotors for 5k's? I bought the powerdiscs for only 
a few bucks more than the OE discs. Are there slotted rotors avail. for as 
good a price? Also, are there any places w/ zinc coated discs? The only one 
I can find are drilled, which is not what I'm looking for...too espensive + 
shorter life. The zinc coated ones look nice though and keep from rusting 
where the pads don't touch. Any advice appreciated.
