FK7 HATCHBACK / FC1 SEDAN's genuine brake disk size is Φ 282, 23 mm thick, but in sports driving the temperature of the brake disc exceeds the race's 500 ° C. Therefore, SPOON has been newly developed for FK 7 / FC 1 based on the 6 POT monocoque calipers that had been testing and developing in Super Durable Series since 2016. The biggest feature of this "FULL Monoblock Caliper" is the capless design, developed without compromise at all in terms of structure, performance and durability. Capless Furumono Body is manufactured with "angle head processing machine". By adopting this construction method it became possible to reduce the number of rubber parts, the liquid loss was reduced, the design of a caliper with high rigidity and light weight became possible.
We adopted large diameter dust boots for ultra-thin piston and meet requirement specification even in street or circuit use.
Uneven wear was suppressed by optimizing PAD surface pressure by different diameter 6 PISTON design of Φ36 / Φ34 / Φ27.
Moreover, by adopting the reverse bench retired disk of Φ 312 25 mm thick, the brake temperature rise and heat collapse are suppressed considerably in sports driving. It also dramatically improved resistance to judder and made it possible to sustain a stable brake feel even in continuous laps.
