Spoon Progressive Spring - Prelude BF1

$425.00
SKU
SP-51400-BF1-001
Available for pre-order.

Spoon Sports adopted a barrel-shaped spring design. Unlike conventional straight-wound springs, barrel-shaped springs can provide multiple spring rates due to differences in the spring diameter (coil size).

By taking advantage of the characteristics of this shape, Spoon achieved a suspension setup that uses a lower spring rate around the 1G load range—where ride comfort is most important—and a higher spring rate during high-speed cornering.

The spring rates were tested across various conditions, including winding roads and mini circuits, and were set at 4.5 kgf/mm for the front and 5.1 kgf/mm for the rear.

The front and rear bump rubbers must be trimmed by 20 mm.

Ride height: FRONT -20mm, REAR -20mm
