Air filters are the first step to tuning any engine. The principle is simple, the more air you get in the engine, the more power you get out. Ok, so there is obviously more to it than that, but bolting on an induction kit can increase your cars power from 1-2bhp, up to 15bhp (rolling road proven!!) With modern ECU's you don't have to re-map or tune the engine, just bolt the kit on! Even a replacement element alone can add a couple of horses, and you never have to replace it, so they quickly pay for themselves. For the maximum power, you can go for a K&N typhoon kit, or an enclosed intake system like the BMC CDA kits maximising cold air intake.
Whether you are into fast road, or track / gravel racing, your car will greatly benefit from uprated suspension. Lowering springs, full suspension kit and coilovers each have their advantages and the range means that we can cater for your suspension needs whatever your budget
Performance exhausts are a great way to improve the power, and sound of your car! Even with just a sports exhaust back box, your car can sound like it means business and have a noticeable improvement in power. For the maximum power increase though, a full exhaust system is the way forward. Sports cat, or de-cat pipe (not road legal) and tubular manifold give further power gains. Free flowing exhausts get the gases out of the engine quicker, and help improve power and acceleration, especially at higher revs.
Upgrading your brakes is vital if you have increased your cars power! It is all very well accelerating like an Aston Martin, but if you stop like a shopping trolley, you are going to be in trouble. We have a large range of options for improving your brakes. Performance pads work great on standard or up rated drilled / grooved discs, improving pedal feel and reducing brake fade and glazing. For serious stopping power then a large disc upgrade or 4-6 pot callipers are the ultimate in braking systems. We have the leading brands including Bembo, Tarox, AP and Hi-Spec all at unbeatable prices.
There are a myriad of ways to tune an engine, and you can just clean it up a little with some Magnecor ignition leads, and some up rated spark plugs, or bolt on a turbo, add a ECU and boost controller, maybe a charge cooler! Whatever you need, we have it, and cheaper than the competition!
We all like a bit of luxury, and you spend a lot of time in your car, so spoil it a little. Some sports seats, leather steering wheel and colour coded leather gear knob and gaiter can make your car a much better place to be! Whether you want the quality of Momo, or the something shiney like Richbrook, DCPerformance have the lot and you wont find any of it cheaper!
Whether you are after a subtle spoiler, or a full on lairy body kit to ensure you never see another car like yours at the shows, then DCPerformance has it all.
You can dramatically update the look for your car with some new lighting. Ditch the orange indicators for some clear or crystal clear indicators, fit some shiny angel eye headlamps, and some LED or Lexus style taillights and suddenly your car stands out from the crowd! We have all the leading brands including Ultra, InPro and Auto Art all at unbeatable prices.
If you are increasing your vehicles power, then you will inevitably put more stress on the clutch and transmission, which is when you require an uprated clutch. From organic to paddle clutches, we have them all. Couple this with a quick shifts for sharp and precise gear changes and you will really be able to feel the different in your 0-60 sprints!
BC Racing is the own brand range of coilover suspension kits from a large manufacturer of suspension products.
The mainstay of the manufacturer is producing units for a wide range of companies including a number
of premium brands within the coilover market. The release of the BC Racing own brand gives end users
the benefit of the knowledge, manufacturing processes and economies of scale of a large suspension
manufacturer but at the prices which are more associated with the lower quality units cluttering the
market at the moment.
Damping adjustment allows you to fine tune your car to suit your needs and the cars intended use.
Adjustment should always be made in axle pairs, so both fronts must be tuned the same and both rears
must be tuned the same.
Decreasing front damping will speed up the weight transfer as you apply the cars brakes thus
increasing front traction. You want some degree of weight transfer to occur to load up the front tyres
to maximise braking ability and to help the front end hook up for corner entry. The front loading helps
prevent under steer.
Such subtle tweaking of the damping rates can make a big difference to the way the car handles.
Coilover and after market damper manufacturers run quality control system that can lead to a large
variation in damper to damper performance. This means that you can have different damping rates at each
corner of your car even when the dampers are dialled in to the same setting via their adjuster. Because
damping settings are so crucial to a vehicles handling, this can lead to a handling imbalance where the
car will pull slightly under braking and its turn in and mid corner handling characteristics can differ
from left to right hand corners.
It's because the damping rates are so crucial that BC Racing check each and every damper they produce
on an in house damper dyno. The compression and rebound damping rates are recorded and the coilover
kits are only put together using matched dampers. Through this in house individual checking BC Racing
can be confident that the kits are produced with matching dampers. BC Racing run to a tolerance level 3
times more accurate than general original equipment manufacturers so the difference in damping rate
between BC Racing units is a third of that aimed for by most original equipment manufacturers.
The BC Racing coilovers are a direct replacement for the original equipment. Unlike other brands of
coilovers, most the BC Racing range do not require brackets fabricating, cable ties or jubilee clips to
install. The bottom mounts come with all brackets to take the original ABS sensor leads, brake lines,
anti roll bar drop links etc.Just take off your original equipment suspension and install the BC Racing
suspension. A straightforward and simple install.
The BR series coilovers use a large 44mm diameter piston in a 53mm 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 BR range with a large 53mm 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.
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.
The car needs to be placing equal weight on each tyre on an axle so both front tyres need to be taking equal loading as do both rears. This makes sure that both tyres are doing their equal share of work when cornering which increases overall grip, maximises corner speed and reduces lap times.
Optional assister springs can be purchased to allow wheel droop to be dialled into the unit to suit specific needs.
Ride height is determined by the position of the coilover bottom mount. The mount can be wound up and down the damper body to give a full range of adjustment from near standard ride height to so low it wouldn't be drivable on the road.
Because ride height is determined by an adjustable bottom mount rather than spring platform you retain full damper travel regardless of the ride height run.
BR 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 BR 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.
If its possible to include camber adjustment on your vehicle then the BC Racing coilovers automatically include camber adjustable aluminium pillowball top mounts. These feature the same high quality Japanese manufactured pillowball but give the added benefit of an adjustable top mount that allows camber to be set to suit your needs be it road, track or drift.
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.
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.
Coilovers use a locking collar to prevent the bottom mount becoming loose. 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.
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.
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.
Because the spring twists as it compresses it is very important to minimise stiction between the spring and its seats. If this tension is not relieved then spring binding can occur leading to the spring rate effectively altering slightly as the spring compresses and extends. The tension generated can lead to rapid deterioration of the spring pearches and in extreme cases can cause the spring platform and locking collars to loosen. This can lead to the platform and locking collars 'walking' down the damper resulting in un even ride height and danger of the spring dislocating under full damper extension.
The friction between spring and seats also has an effect on steering effort as the springs are physically turned with the wheels. This introduces additional unnecessary friction into the steering system which has a knock on detrimental effect on the vehicles handling characteristics.
The bearing mounted upper spring platform is one of BC Racings innovative designs. By vastly reducing stiction between the spring and its seats the BC Racing units avoid the above problems thus improving the efficiency of the steering system and allowing the spring and damper to work as designed.
Damper adjusting extenders - to save you the time and trouble of removing the parcel shelf each time you want to adjust the damping on your BC Racing coilovers we can offer pairs of adjuster extenders. These attach to the adjuster knob on the top of the coilover and are available in three lengths, 110mm, 200mm and 250mm. They attach in seconds with a simple grub screw design.
Assister spring perch - you might prefer to run some droop with your coilovers or maybe you want to alter the ride by adding an additional smaller assister spring. The spring perch and assister springs allows you to do this. The springs are available in a wide range of spring rates.
Pillowball top mount - some applications come with hardened rubber top mounts as standard to ensure the highest quality ride and keep costs as reasonable as possible for road use but we often offer a pillowball upgrade for these vehicles should you want to remove this flex and make the car a little more hardcore. Upgrading to pillowball eliminates the flex inherent in even the hardened rubber used by BR Racing so improving the handling for those looking for the ultimate.
