These rotors are engineered to integrate flawlessly with the standard 2005–2012 987 chassis Cayman S or Boxster S calipers, delivering a true bolt-on solution with no bearing spacers, no machining, and no permanent modifications. The system uses a staggered rotor setup, 350mm front and 330mm rear, that preserves factory front/rear brake bias and fits 18-inch wheels and select 17-inch wheels, with your choice of drilled or slotted faces.

At the core is a true race-style floating rotor design using H-style bobbin hardware. This architecture allows the rotor ring to expand independently of the aluminum hat as temperatures rise, isolating thermal stress and preventing distortion. The result is a braking surface that remains flat and stable under repeated hard use, maintaining consistent pad contact and predictable pedal feel.

Floating hardware also allows the rotor to self-center within the caliper as loads change, reducing lateral runout and minimizing pad knockback during aggressive driving. Pedal height is preserved and modulation improves because braking force is no longer compromised by heat-induced rotor movement.

Even with the larger diameter, the total assembly weight is comparable to stock, retaining suspension response while significantly increasing thermal capacity. By relocating mass away from the hub via the aluminum hat, the important actual rotor ring mass is increased which improves heat absorption and dissipation. In addition to greater thermal mass and faster heat shedding, the system delivers stronger initial bite and consistent stopping distances, even as temperatures climb.

On the road or track, this system represents a fundamental improvement in how the Cayman or Boxster braking system manages heat, load, and stability, delivering repeatable braking performance beyond factory component limits.
