993 Rotor spec
A few people have requested this info. I received this from another rennlister and used it to order a set of slotted rotors from Coleman last year. I had good luck with them, no issues, seemed well made. I used them on the street and track. I swapped Textars and Pagid yellows in and out with no issues. I finally wore them out after a year (15k street or so) and a dozen or so DE days. These were used on my 1996 C4S. Cost was around $110 each plus shipping.

Yes. I did not replace the hardware but I have since been told I should. Also a few people have said their experience is your hats will eventually fatigue and should be replaced periodically. I do not know where to get only hats in stock form. Coleman is able to make hats I do not have the spec for them though.

You can't buy just the hats either, I used to give him my discarded rotors w/ hats but i don't use them any longer
last point, those hats are heavy
If you are tracking the car a lot, Gyrodisk or similar floating aluminum hat rotors are they way to go, their slotted versions last a long time, I have over 6000 track miles on mine w/ much more to go, I never got more than ~4000 track mi on the oe drilled 993tt front rotors

The Coleman annuli are 110 ea vs I think close to 300 ea for the gyrodisc. Are you getting three times the wear? As a newer driver I feel I am using my brakes more than I need to so my wear is greater than yours I think. I dont think the Coleman wear any better or worse than the stock, which are on my car right now. (they got thin and I forgot to order a new set)

Perhaps the best option is for Coleman to replicate the Girodisc rings. Can't imagine they would be much more than stock. My experience is the same as Bill's, I love the Girodisc but would certainly like to have the option to replace rings at 1/3 the price.
