Description
An FRP rear brake stay aimed at undulating circuits, where consistent braking before slopes and jumps helps a car complete the full distance without flying off. The stay is molded in rigid FRP with a wide surface area for mounting brake sponge, and its shape is designed to sit clear of the car's rollers. Multiple mounting holes allow optional parts such as mass dampers to be fitted to the same stay.
- Material: rigid FRP
- Includes 2mm thickness brake sponge (red) and attachment hardware
- Compatible chassis: MA, MS, FM-A, AR, VS, Super-II, Super X, Super XX, Super TZ-X
Mini 4WD cars run a fixed-speed motor with no throttle or motor braking, so a friction brake like this stay is the only way to scrub speed before a slope or jump. Mounting the brake at the rear, rather than only the front, also helps control the car's attitude in the air, since a rear brake can be tuned differently to change how the car pitches on landing.
