Description
SET MONO4 Monoblock 4-Piston Caliper
The one-piece evolution of the RX4. The MONO4 takes everything that makes the RX4 a competition-grade caliper — 25ms build time, nickel-manganese pistons, 240°C seals — and packages it in a monoblock (one-piece) forged body weighing just 2.22kg. The result: reduced deflection, improved thermal conductivity, and the lightest 4-piston monoblock caliper in its class.
MONO4 vs RX4
Both share identical piston configurations and racing specifications. The MONO4’s one-piece construction eliminates the bolted centre joint, delivering measurably less deflection under extreme loads and better heat transfer through the caliper body. For drivers stepping up from the RX4, the MONO4 is the natural progression.
