■ Monocoque caliper set Since the opposite caliper can be set to have a higher body rigidity than the embossed type, it has advantages such as lower drag torque value and no pad wear. The monocoque caliper has a monoblock structure and a precision mold casting method. It can be installed with bolts on without any processing and can be used for front and rear brake distribution and ABS as it is. In addition, the pad used is the same shape and size as the genuine S2000, and the rotor size is up to 300 mm and the rotor thickness is up to 26 mm. When installing a monocoque on CL7, DC2, EK9, we have prepared a dedicated brake rotor of 300mm t = 26mm.

In sports driving, it’s really all about braking. Pressing down on the brake pedal, the nose dives and the driver fights the rear with steering and gas pedal control. Our caliper development focuses on that very moment of excitement. We start by designing the cast. Applying precision aluminum forging technology, the caliper is designed with a 4-piece opposed monocoque structure with variable diameter pistons. The forged caliper support is deeply inserted into the caliper body to securely embrace the hub knuckle. Such design enhances the overall rigidity, minimizing drag torque and bias-wear of brake pads. As the next corner opens its jaws, the driver can fully commit to the last braking point, making the rear follow his lead. Only after mastering the art of braking, the true sensation of sports driving will be rewarded to the driver. Commitment to the true essence of driving. That is where all begins with Spoon.
Validness of the rotor diameter and thermal accumulation
The caliper spec is determined by the rotor diameter and thickness (thermal accumulation). Rotor size is dependent on rim size. At Spoon, we’ve developed twin-block calipers for 15-inch rims and monocoque calipers for 16-inch rims. Here, we will explain the technology behind our monocoque calipers.
Purposive caliper body design and
The caliper features a forged aluminum body offer-
ing minimal weight, plus freedom in design using
purpose-built secondary fabrication equipment. The
variable diameter pistons placed in opposed position
delivers balanced pad pressure. We exposed the
calipers to extensive testing to detect the slightest
change in brake fluid pressure and minimizing the
knock-back amount of caliper pistons, all for the
sake of improving brake performance.
Analyzing variable diameter
By means of stress analysis, we can derive the
optimum surface pressure distribution on the brake
pads. Incorporating such data, we were able to
minimize bias-wear and balance the pressure on
the pad surface. Parallel to such desk-top analy-
sis, we spent time participating in the Nurburgring
24 hour races and other enduro venues. From
there, we gathered valuable real-life data and
experience that was essential to our R&D.
