Following the new 3S linear shock springs for the NT1 Xray now also introduce RX8 specific sets. The 3S springs are specially designed for the new shorter low profile shock absorbers and are shorter in length with the rear one now sporting the same dimensions as the front spring. The laser-engraved, selected and matched parts make for more corner entry steering and are available as C=3.5 to 5.5 and C=7.0 to 8.0 variants with the lower numbers marking the softer springs.
