Floating hats
Well after a few high mileage track days it looks like my steel rotors are toast. I have heard a lot recently about floating hat rotors with the less unsprung weight and better heat disapation. What is the full story...is it still less expensive to find non-OEM rotors and keep the stock set up or is it a worthwhile investment due to longer rotor life and other such factors? Please explain the cost/benefits, the best source(s), etc. Is there a long lead time? Thx.

The current crop of full-floating rotors (AP & Alcon) are made of a FAR better grade of cast iron than the OEM or Cup rotors.
For that reason, they are much more durable and weigh 3-4 lbs per corner less than OEM or Cup rotors. Being full-floaters, these do not contribute to pad knock back and are very difficult to warp as they are much more thermally stable.
Depending on time of year and how busy we are, I usually have these on the shelf. If you need more info, please feel free to E-mail me directly.
Just remember, any full-floating rotors need some periodic cleaning & maintenance, compared to their solid, bolted up cousins.

Holger, a bunch of us in Las Vegas put them on due to OEM rotor life being only about 1,000 miles (track).
We are using the AP brand only because it is the one used for the 24 heures du Mans. If it lasts under 24 hours of race conditions, it should last me a whole season. So far, I only have about 10 track hours on them. They are wonderful and durable so far. I will update as how the season goes, but they cost about 20% more than OEM, and I'm guessing they will last at least 3x as long. Why 3x? 24 hours x 125mph average speed= 3,000 miles under race conditions (conservative).
I got mine from Kent Moore at Premier Sportscar Service. Anyone coming to the 48 hours of Las Vegas event can see several sets of them. They do make a small clanging noise audable when your engine is under 3,000 rpm. Also, it is important to bed them in correctly (Not hard).

Philip, thanks for the info.
Just to clarify, OEM refers to CUP rotors?
"They do make a small clanging noise audable when your engine is under 3,000 rpm." I'm assuming this is only in first gear?

Thanks to mi amigo Jack, I made the plunge to the 3rd gen. Brembo floating hats. They will be installed later this week at Lucent. The newest version is lighter with greater heat disipation, etc. Let the games begin!
