Warranty:
BC offer a 12 month warranty with all of their coilovers apart from the RM and ER series which have a limited use warranty. They are so confident with the quality that they now offer an extended warranty for $100 meaning they will be covered for 24 months!

Nitrogen pressurised dampers:
When 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.

Corrosion protection: The damper units are black chromed steel to give superb durability even through the darkest of European winters. The aluminium components (top mounts, locking collars etc) are anodised and the steel lower mounts go through an electrophoretic disposition process followed by powder coating. A random selection of steel components (brackets, dampers, screws etc) are put through a salt spray test once a month to check the quality of the protective processes and that anti corrosive properties are kept at the highest possible standard.

High quality coil springs:
BC Racing coilovers only use the highest quality steel for their spring manufacturer. They are produced from SAE9254 high strength durable cold wound steel.
 
The springs are compression tested through over 500,000 cycles with less that 5% deformation.

High quality oil:
BC 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.
 
As 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.
 
BC 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.

The V1 series coilovers use a large 44mm diameter piston in a 50mm diameter damper body to maximise oil capacity.
 
As the damper unit opearates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit.
 
BC Racing only use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their V1 range with a large 50mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.

Ride height is adjustable by both the base of the shock and the spring base itself so you can achieve the perfect setup for you vehicle

V1 coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.
 
By tweaking front and rear damping you can adjust the way the car handles. Increasing damping force on the rear relative to the front, for example, will start moving the vehicle into a more oversteer orientated stance.
 
If you want to go drag racing in a rear wheel drive car then you want the back of the car to squat off the line to maximise weight transfer to the rear and therefore onto the rear tyres. This maximises traction and helps prevent wheel spin. To achieve this you would soften the rear dampers to allow faster compression. If you had the rear dampers set to hard, as you might run the car on a race track, then the car would be less inclined to squat so traction would be reduced.
 
Conversely, if you want to go drifting and are finding it hard to break traction and are having problems with understeer then making the rear dampers harder will help reduce traction whilst making the front dampers softer will give greater front traction. This will make the rear of the car looser whilst minimising understeer thus altering the vehicles handling characteristics more towards drift than drag, road or track.

Many of the BC Racing V1 coilovers come with pillowball upper mounts. The mount itself is made from aluminium alloy, anodised and then bead blasted to give a high quality, durable finish.
 
The pillowballs themselves are of Japanese manufacture and their solid nature eliminates any flex or play associated with the standard rubber mounts so improving response and handling.

Inverted damper:
The BC Racing RM series feature high quality damping adjustable monotube inverted dampers at the front or front and rear, depending on vehicle. Inverting the damper unit brings with it a number of advantages.
 
Reduced unsprung weight:
Unsprung weight is reduced by moving the oil and gas reservoir way from the hub and attaching it to the shell. Unsprung weight is vital to a cars performance as a lighter wheel and hub assembly which readily moves in response to road bumps will have more grip when tracking over an imperfect road. A high unsprung weight can lead to wheel hop over bumpy ground and will reduce the quality of the ride and also ultimate handling as anything that impairs the suspension ability to maintain contact between road and tyre will be of detriment to the cars performance.
 
Reduced heat transfer to the gas and oil reservoir:
By inverting the oil and gas reservoir the oil and gas is moved away from the hub assembly, this reduces the amount of conducted heat being transferred from the braking system to the hub then to the damper and then on to the gas and oil. By keeping the gas and oil temperatures down BC Racing RM coilovers keep damping rates more consistant resulting in better performing suspension and ultimately allowing you to corner faster, which is the bottom line.
 
Reduced flex:
The large 42mm damper rod and inverted design gives the inverted damper units much greater strength and resistance to side loadings. By reducing flex the RM inverted units lead to more consistent steering geometry resulting in more predictable and responsive handling.
 
Corner weight adjustment: The lower spring platform of the BC Racing coilovers are adjustable.  This allows the car to be set up for corner weighting to achieve perfect balance and ensures that maximum tyre efficiency is achieved. 
 
Ride height is adjustable by both the base of the shock and the spring base itself so you can achieve the perfect setup for you vehicle

External Reservoir ER Series
bcer
BC Racings premium flagship coilovers are the external reservoir ER Series with separate compression and rebound damping adjustment.  The ER Series coilovers bring with them the high quality and unique features seen on the BR and RM type but have the additional benefit of external reservoirs and the ability to allow the end user to individually adjust and set compression and rebound damping rates.
 
External reservoir  
The external reservoir ER Series coilovers allow BC Racing to increase the oil capacity of the damper unit.  The additional oil capacity reduces peak oil temperatures which decreases variations in damping rates due to oil viscosity changes.  The reduction in damping rate variations improves handling and ultimate on road and track performance.
 
Separate compression and rebound damping adjustment  
By separating the adjustment for damping compression and rebound the ER Series allows you to dial the vehicle in to your exact needs.  When braking hard whilst approaching a corner you want the car to transfer weight to the front tyres to maximise grip for the braking effort and also to allow you to trail brake into the corner without the car understeering.  
 
As you start to lift off the brakes on corner entry you donít want the suspension to snap back up too quickly as this will remove the loading from the front tyres too quickly and lead to understeer.  As soon as the car starts to understeer you need to wind off the steering lock to reduce the work effort applied to the tyres to allow them to regain traction.  This slows the vehicles ultimate speed.
 
The compression damping adjustment allows you to fine tune the way the car rolls onto its front tyres during braking and the separate rebound adjustment allows you to fine tune the way the car responds as you come off the brakes to enter the corner proper and keep the front end hooked up.  This allows you to get back on the power sooner and maximise corner exit speed.  Corner exit speed is vital because this determines your maximum speed achieved down the next straight.
