PREMIUM CONTROL ARM AND BALL JOINT

The StopTech ST-40 is a 4-piston brake caliper designed for performance upgrades. It is manufactured from a squeeze-forged aluminum alloy and utilizes standard FMSI D372 brake pads. The caliper features differential piston sizes to minimize pad taper and includes dust boots to protect the pistons from contamination.

StopTech calipers are known for their stiffness, thanks to a patented bridge design that prevents distortion and aids cooling. This stiffness contributes to better performance with no vibration or noise, no radial pad taper, and improved pedal feel. The ST-40 caliper is 100% leak down and pressure tested to 2,500 PSI.
