What the R12 front spring does

The Yokomo R12-18FSP is a single-piece front shock spring for 1/12 R12 front ends, made to alter roll stiffness and rebound feel for improved turn-in on race or club tracks.

Fitting is standard for R12 dampers: remove the dampers from the car, take apart the cap and shaft as needed, slide the spring onto the retainer or cup, then reassemble the shock using your chosen oil and preload. Clean components before rebuilding to avoid binding.

Tuning tips: try one change at a time—swap springs, then adjust oil or preload—to clearly identify how the R12-18FSP affects corner entry and mid-corner balance.

Packing includes

  • Front shock spring - 1 pcs
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.

How will this spring change turn-in and mid-corner grip?

A stiffer front spring tends to sharpen turn-in and reduce body roll, while a softer spring smooths initial bite; pair the R12-18FSP with appropriate oil to refine rebound response for the desired feel.

Should I change front oil when using this spring?

Not always, but small oil adjustments can complement the spring rate—test with your current oil first, then alter viscosity in small steps to balance rebound and compressive behavior.

Is this suitable for competitive setup work?

Yes, the R12-18FSP is intended for setup tuning on 1/12 R12 platforms; use it alongside measured changes to preload and oil to build a consistent handling package.
