Renault Clio Sport 182 BC BR RN Series Coilover Suspension Damper 04-06. BC BR Series Coilovers are designed for street and track use. With 30 levels of damping they can be tuned to a harder level for sustained track use, or a softer level for a more compliant road/street experience. Spring Rate (F): 4.0kg. Spring Rate (R): 8.0 kg.Is generic some are correct! And may not be the exact model for your vehicle.
Factory processes, finish and build quality is the same for all models. Adjustable spring platform which allows corner weighting to achieve a proper race setup: 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.
Height adjustment via bottom mount to retain full damper travel. Bearing mounted upper front spring platform. Dust boot to protect damper seals.The BR series coilovers use a massive 46mm 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. Discount available if you call the office! Pillowball (rose joint) upper mount.
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 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. 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. 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.
Patented concave lower locking collar. Coilovers use a locking collar to prevent the bottom mount becoming loose. 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. BC Racing ensures that only high quality oil is used so that damping rates are maintained not only for the moment in hand i. 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. Bearing mounted upper spring platform. 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. 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. We send 98% of our items using a tracked and signed service unless the value/availability of the product means that we can quickly and easily send a replacement to you. If you are struggling to get a quote you may be better heading over to our website or sending us a message.
Collections: We are open from 9.30 until 5.30 every day and collections are welcome, especially on larger items. There will be a surcharge for non-mainland addresses as it costs us more to send items here. Below are some of the answers to questions you may have.
Damage in Transit: Nobody is perfect and from time to time parts do become damaged in transit as much as we try to avoid this. This is also clearly stated in the advert. Item Not as Described: We try and be as accurate as humanly possible with our descriptions. This may mean extra photos of damage or a clear description of any wear or tear.Opinions, however, are subjective, and if you feel that the item has not been described accurately, please notify us and we will aim to resolve the issue. New Items: Will be in perfect, boxfresh working order, unless otherwise clearly stated. We do security mark all of our parts as time to time, some customers do try to make fraudulent claims.
We do not tolerate this at all. We know what it's like when you need a replacement part so you can race or simply play out by the weekend. We are based in Lytham St Annes just next to Blackpool. Our staff have been playing with cars for years and as a result we are in a good position to advise on fixing them.
We have our own project vehicles which we upgrade and play with in our spare time. We've experienced most of the common problems as well as a few less common ones! If you do require any advice on your parts, we are happy to help.
We also offer a fitting service for most of our parts and operate a fully kitted garage. Please message us if you require any further help or information about this.
