This lower A-arm front spring is designed for the Yokomo R12-10SSS fitment on R12/GT series chassis and uses a super soft rate to promote a compliant front end feel on compatible R12 variants.
Use it to reduce front spring stiffness, encourage low-speed weight transfer, and fine-tune bite and turn-in for setups that benefit from a softer front axle response.
Note that fitment is limited to the listed R12/GT models and it is intended for the lower A-arm spring location on those cars.
