Ultra soft front lower A-arm spring for Yokomo R12

This ultra soft lower A-arm spring is built for front suspension adjustments on Yokomo R12 and the matching GT series RC cars. It provides a softer initial rate at the lower A-arm to alter front compliance without changing suspension geometry.

Choose this spring when you want gentler front support to improve mechanical grip on low-traction surfaces. The softer rate delays roll onset and changes steering feel; pair with ride height and damper tuning to regain predictable balance.

Fitting is simple on compatible R12/GT lower A-arm assemblies: replace the stock lower A-arm spring with this unit, then check clearance through full travel. After installation, review preload and damper settings to rebalance front-to-rear behavior.

Compatibility: GT5-R35, GT5-SC430, GT3-REA, GT3-IS350, GT3-B4, GT3-CAX, GT3-BRZ, GT3-AHP, GT-B, GT5-R2, GT5-RS2, YR-R12C3, YR-R12C31.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which stock spring is swapped for this part?

This item replaces the stock front lower A-arm spring on supported R12/GT models. Verify the part number against your chassis before ordering to ensure fitment.

How will an ultra soft lower spring change handling?

An ultra soft spring increases compliance at the front, improving traction on slick surfaces but reducing immediate steering bite. Adjust damper compression and rebound along with ride height to tune balance.

Is this compatible with my chassis code?

Check the compatibility list above and compare your chassis codes or send the chassis ID to the supplier for confirmation before purchase.
