The OEM valve operates in this same manner

Made from billet alloy and using a single piston this valve will run faultlessly without the need for attention and eliminates the longevity problems associated with the original diaphragm valves

The bar and plate core has over 129% more volume and an increase of frontal surface area over 71% (over the stock cooler) meaning the Forge Motorsport intercooler is the largest currently available on the market

As the damper unit operates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristics of the unit. The RA series coilover kits are supplied with aluminium front top mounts with pillowball centres (camber adjustable if macpherson) and aluminium rear top
