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.
