Does anyone know of a 13.06" diameter/ 1.250" thick one piece rotor that will work with the Wilwood SL6 big brake upgrade kit on a C5 Z06? My rotors are shot after a couple of track days, and not really interested in spending $175/ea for replacement rotor rings, if I can avoid it. It seems that the stock NAPA rotors are around 12.8" in diameter, too small for the Wilwood setup. A straight 13" rotor would be fine (.06" won't make a difference). If anyone knows a source and part number for a good rotor alternative, it would be greatly appreciated.

check with gary at hardbar. I think hes got hats setup to use a coleman rotor.

I know PFC has direct drives in 13.07 x 1.25"

Cost will be high though. Prolly $300-400 each.

I could set you up with a slight alternative rotor Steve. The max width for the BSL6 caliper found on the factory kit however is about 1.300 so total width gains are minimal. Producing a Coleman part with the proper casting could boost the total miss up a tad as well. All good things.

I must confess however that the standard Wilwood GT rotor is probably about the same weight. And if you're picking them up for about $170ea that's about right. The alternatives won't be significantly less and last vastly longer. If I were to venture a guess; a few bucks less and probably 25% more life.

I think you'd do well to consider some ducting for whichever way you choose. Lowing operating temps will help greatly.
