Replace Rear Carbon Ceramics Without Compromise

This Girodisc rear steel disc conversion kit — also referred to as iron rotors — is a direct-fit replacement for the factory 390mm PCCB (carbon ceramic) rear discs found on high-performance Porsche GT models. Whether you're saving your OEM ceramics for resale or want predictable, fade-free braking on track, this conversion delivers lasting performance and cost efficiency.

Sold/priced per pair.


Why Convert from PCCB to Steel Discs?

Ceramic discs are excellent for occasional fast road use, but steel rotors offer distinct advantages under more demanding conditions:

  • Better thermal stability for track days and competition

  • Improved brake pedal feel and control

  • Reduced long-term maintenance costs

  • Compatible with motorsport pad compounds like Ferodo DS3.12, Endless ME20/22, or PFC 08/11

🔧 Note: For optimal performance and brake balance, we strongly recommend converting front and rear discs together.


Key Features

  • 2-piece floating steel rotors

  • Lightweight, anodised 6061-T6 aluminium hats

  • Directional curved vane cooling for consistent performance

  • 390mm diameter – direct replacement for OEM PCCB rears

  • Fully CNC machined in the USA

  • Retains full compatibility with OEM yellow calipers and brake lines

  • Ideal for fast road use, endurance racing, and circuit driving

  • Once the Girodisc kit is installed, you’ll only need to replace the disc/rotor when worn. New hardware is included with replacement discs, and the aluminium bells do not require replacement.


Compatibility

  • Porsche 991.1 / 991.2 GT3

  • Porsche 991.1 / 991.2 GT3 RS

  • Porsche 991.2 GT2 RS

  • Porsche 718 Cayman GT4 RS

⚠️ Only suitable for vehicles originally equipped with PCCB rear brakes. Not compatible with models that came with steel brakes from the factory.


Front Conversion Also Available

This rear kit is designed to be used in conjunction with the matching 410mm Girodisc front conversion kit, available separately...

Best Clay for Natural Look and Feel!
As a hairstylist with a very strong focus on men’s hair for over 20 years, I applaud the guys at Highland for what they are doing. A product line with quality and minimal ingredients we can actually read and understand. This clay is what I have always wanted!! Sure you’ll see some reviews talking about how there isn’t enough hold or it’s not even a medium hold when it says it’s strong hold on the package, but you have to understand, when a product is this clean, strong hold isn’t going to feel like the strong hold in the garbage products most of us have used. This is a strong hold, in terms of keeping your best natural look all day. Something you can work into place, then continuously run your hands through all day and it still looks great. The men’s clay from Davines does a wonderful job at this too, but there’s something about the finish of this product that literally brings out such a healthy natural look. Not shiny either and definitely does not give you a wet look out of the shower. If you see that kind of review, the guy most likely has greasy hair, is using cheap conditioner, or perhaps applied too much. Don’t over use this product in your application, you get the best out it. Amazing work Highland, keep it up!

Amazing product, definitely recommend!
Initially I was very skeptical about buying this product and kept talking myself out of it, did that a few times. I was under the impression that this was just an incredibly well orchestrated marketing campaign(it kept popping up all over social media) and people just out there overhyping it all. Yesterday I finally decided to give it a try and I have to say, BOY WAS I WRONG, this is probably the best hair product I’ve used in 15 years. Gives a natural matte look to your hair, it’s not greasy, gives plenty of volume and holds your styling in place in a very natural manner. The product also smells pretty good, HIGHLY recommend if you’re having doubts.

It delivers, but damn is it expensive
This product mainly shines because everything available at a brick and mortar shop is terrible - at least for men. This is great stuff, great hold without being greasy or turning your hair into spikes. No pungent odors. It's noted that it includes pine and sandalwood oil. There's definitely some pine, not getting any sandalwood. Regardless, it isn't a strong scent and that's how it should be. The tin is almost exactly the size of a snuff can. Expensive. But you don't really use much of it at one time.
