The Yokomo R12-21SSS rear side roll spring is intended to give a softer rear roll characteristic for YRX12, GT and YR-10F chassis. Its super soft rate helps improve handling fidelity and steadiness through corners. The spring works with several chassis variants, including YR-R12C3 and YR-R12C31, allowing versatile setup choices.

What models will accept the R12-21SSS spring?

It is compatible with YRX12, GT and YR-10F platforms and fits related chassis like YR-R12C3 and YR-R12C31 as noted by the manufacturer.

Will this spring suit low grip tracks?

A super soft rear spring can help the tyres maintain contact on lower grip surfaces, improving rear traction, but pairing with correct dampers is important.

Do I need other parts when fitting this spring?

No special parts are required beyond standard spring retainers, but you should review swaybar and droop settings to match the softer rear rate.
