This front lower A-arm spring is produced for the Yokomo R12/GT line and is intended for carpeted track conditions. It substitutes the original front lower spring in the R12/GT front suspension to give a defined spring characteristic for carpet racing.
The part is designated R12-10S1 and is compatible with R12/GT models as a direct replacement for the stock front lower A-arm spring. To fit, remove the front lower arm assembly, swap the spring element, then reassemble the suspension to the factory geometry.
In setup terms the R12-10S1 modifies front compliance and initial turn-in on RC carpet. Use it while fine-tuning front balance for grip and steering precision, and evaluate handling changes across short on-track tests.
