This 1/12-scale accessory is a front lower A-arm spring offered by Yokomo as model R12-10LHS, specified hyper soft for R12/GT series configurations. It is intended solely for RC chassis tuning.
The spring is a front suspension component for R12/GT series cars and delivers a softer spring rate to raise front compliance, which helps modify front grip and body roll during low-speed transitions and over fine surface roughness.
Installation overview: the spring seats on the lower A-arm spring perch of the front suspension on supported R12/GT chassis. Follow the chassis manufacturer's standard front suspension disassembly procedures when swapping springs, and inspect spring seating and suspension travel after installation.
Tuning role: apply the hyper soft lower A-arm spring when you need the front to absorb small bumps more readily or to slightly tone down immediate turn-in bite; combine with matching damper oil and sway bar tuning to achieve the desired balance.
