This part is a graphite lower brace intended for 1/10 scale formula cars and specified for the YR-10F chassis. It serves as a lower chassis reinforcement to influence flex characteristics and support handling refinement on circuit layouts where high grip is typical.
Fitting the YR-04 is simple for those who service a YR-10F: remove the factory lower brace, set the YR-04 into the original location, and fasten with the existing mounting points and hardware. No additional drilling or modification is required for a standard YR-10F chassis.
Tuning role: adding a stiffer graphite lower brace changes roll and pitch response; this YR-04 is intended to increase lateral stiffness in a predictable way without altering suspension geometry. Combine its use with spring and damper changes to reach the desired balance.
Compatible chassis: YR-10F only. Designed specifically to match the standard mounting layout of the YR-10F 1/10 formula platform.
