If the bottom mount becomes loose then the damper body can work its way down into the bottom mount so reducing ride height on that one corner which can lead to dangerous handling characteristics. This is a very common problem for coilovers in general. BC Racing utilise an innovative and patented designed lower locking collar with a bevelled edge that seats into a corresponding bevel in the coilover bottom mount. This vastly increases the surface area that the locking collar works on and so prevents the common and dangerous problem of the locking collars working loose.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eHigh quality oil\u003c\/h3\u003e\n\u003cp\u003eBC Racing dampers use a sophisticated shim stack design and high quality oil to consistently control the compression and rebound speed of the damper rod even under the most extreme conditions.\u003c\/p\u003e\n\u003cp\u003eAs the vehicles travels over rough ground the compression and rebound motion of the damper rod heats the oil. Poor quality dampers use cheap oil whose characteristics alter with varying temperatures. Its vital that high quality oil is used that can maintain consistent viscosity under a wide temperature operating range. Once the oil start to degrade, its properties change leading to damping changes leading to changes in the vehicles handling characteristics.\u003c\/p\u003e\n\u003cp\u003eBC Racing ensures that only high quality oil is used so that damping rates are maintained not only for the moment in hand (i.e. whilst out for a back road blast on or track) but that long term longevity is maximised with oil that doesn't degrade quickly over time thus extending the dampers operating life significantly.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eNitrogen pressurised dampers\u003c\/h3\u003e\n\u003cp\u003eWhen you work a damper hard on track or on high speed bumpy roads you can cause the oil to aerate and cavitation can occour. This causes foaming which effectively reduces the oils viscosity and so reduces the units damping effect. High quality oil goes a long way to help reduce this problem but BC Racing go one step further and pressurise the dampers with nitrogen. The nitrogen exerts a pressure on a floating piston which in turn exerts a permanent pressure on the oil dramatically reducing aeration and so improving the consistency and quality of the damping. The pressurised nitrogen also adds an additional element of effective spring rate to the damper unit.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eBearing mounted upper spring platform\u003c\/h3\u003e\n\u003cp\u003eBecause the spring twists as it compresses it is very important to minimise stiction between the spring and its seats.
