Tune Your Rear Roll Response

The Yokomo R12-21SSH rear side roll spring is manufactured from super hard copper to provide steady rear roll characteristics during aggressive driving. It suits drivers who tune YRX12, GT and YR-10F chassis and want reliable, repeatable behaviour lap after lap.

Model Compatibility and Flexibility

This spring is suitable for several Yokomo chassis, including YR-10F, GT5-R35, GT5-SC430 and GT3-REA, making it a sensible choice for racers who change setups between events. Its uniform stiffness supports consistent tuning decisions.
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.

Does the R12-21SSH affect cornering speed?

The added rear stiffness tends to stabilise the car at higher corner speeds, reducing roll and helping the chassis hold a cleaner line through fast turns.

Can I swap this spring between GT and YRX12 cars?

Yes, the design accommodates multiple Yokomo GT and YRX12 family cars, so it can be moved between compatible chassis when testing different setups.

What setup changes are common after fitting this spring?

Drivers often tweak front roll and damping to maintain balance, and may adjust toe or camber for optimal tyre contact after increasing rear spring stiffness.
