Let’s talk about stopping power with a side of real-world practicality. The Girodisc A2-146 Rear 2-Piece brake disc Kit isn’t just an upgrade for your Porsche 911 (991.1 or 991.2)—it’s a smart move for anyone who’s serious about driving. This system bolts right up where the stock brake disc sat, so there’s no messing around with extra parts or surprise trips to the mechanic. Your factory calipers stay, but the whole feel gets sharper.

Now, here’s where things get interesting: Each Girodisc brake disc is about 2kg lighter than stock. That doesn’t sound like much—until you feel your car react faster off the line and handle with a bit more agility. Swapping out just the cast iron ring down the road makes life (and maintenance) easier. It’s almost like these brake discs were designed with real drivers in mind.

And if you’re a detail person, you’ll appreciate how every bit of this kit is about performance you can actually feel—right out of the box.

  • Direct replacement for factory rear brake disc (no modifications needed)

  • Two-piece floating construction with curved slotted finish

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

  • Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content.  Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
  • Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
  • Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
  • Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
