Rear Coil Spring for F101/102 Chassis Tamiya 5005032 58174/118  [5005032]

Spring for F101/102 rear suspension

This rear coil spring serves as an RC-scale replacement for the rear suspension of compatible F1-style Tamiya chassis. It is identified by the internal code 58174/118 and allows changes to rear suspension response without altering the shock body itself.

Use the spring to renew tired rear springs or to tune rear-end behaviour for better balance. Installation normally involves removing the rear shock, swapping the coil, and refitting the existing shock cap and spring retainer; standard RC hand tools are typically sufficient. Check fit against F101/102 Group C rear mounting arrangements prior to final installation.

For tuning, combine spring swaps with incremental tweaks to shock oil weight, preload, and mounting position to find the preferred roll and traction characteristics. Keep a setup log to reproduce effective configurations for different tracks and surfaces.
