I'm starting to think about rotor replacements for my 991.1 TT with iron 5 lug brakes. Mostly street but occasional track. The OEM rotors are floating pin and 380mm. Is there a significant advantage to Girodiscs, which are also 380mm and floating pin? Price is $1600 for a pair of Girodiscs vs. around $910 for OEM (at Suncoast). Definitely not saving money with the Girodiscs, so must be some other reasons. https://www.suncoastparts.com/catego...RAKESCAST.html

I put these on my hellcat because they made a rear full floater, when even the factory did not. These are GREAT rotors compared to the stock Brembo's that came with the car, they reduced the weight, and they don't warp under high heat. I would have these on every car, but most of my cars have carbon ceramics. They were the same price as my hellcat stock rotors

I swapped out my PCCB rotors with Girodisc because the PCCB just does not last under track use, and they are insanely priced to replace. The Girodisc are excellent, and you can replace the disc only and use the same hat, which will be cheaper than replacement OEM rotor/hat next time. Also, Porsche uses drilled rotors that crack and fail much sooner than slotted, with zero cooling benefit. No race car uses drilled rotors, only slotted. Talk to Clark at Apex Performance about all things brake related. Seriously.

Thanks, Randy. Can you post or PM me with Clark's contact info?

I put a set on about a year ago, with Ferodo 4664 pads. Very happy with them.

That's the rest of the advantage of going with Girodisc slotted rotors. You can go with a more aggressive brake pad. I went with Ferrodo DS1.11, which is also known as part number 4664, too. The net result is excellent.
