Yokomo B10-SSP20A Progressive Spring for BD10F Rear Suspension  [B10-SSP20A]

Rear Suspension Tuning with Yokomo B10-SSP20A

The Yokomo B10-SSP20A Progressive Shock Spring is aimed at fine tuning rear-end behaviour on FWD touring cars. Its 2.0 to 2.3 progressive rate helps smooth out track feedback while keeping the rear stable under load.

Unequal Pitch for Better Absorption

The unequal pitch coil design increases damping efficiency for small bumps and chatter. That progressive action gives a compliant initial feel with firmer reaction as compression increases, useful for consistent corner speed.

Fits Several Touring Chassis Options

This spring is compatible with MRTC-BD10FF, MSR-BDFWD, MSR-010FE, MSR-010FEA, MSR-BD12, and MSR-BD12A, so you can swap it across different platforms when testing rear setup changes.
