Overdimensional D2 Racing Brake Kit
Overdimensional D2 Racing brake kits they are one of the best solutions if you want to significantly increase the braking of your car.They are indicated for users who have problems with the effectiveness of the original brakes, as these are designed to work in cold and preserve an emergency brake in normal circumstances.
The brake kits The D2 Racing they are especially recommended for users who enhance the performance of their cars to do sports driving on trams, tandas on circuits, track days, etc. In these cases it is not only recommended but almost mandatory, since obviously the brakes of origin will be short and we should enhance the brake at least in the same proportion as we enhance the engine.
When we use the brakes of the car daily when traveling by city, road, highway, etc. we are making a use of the brakes that is far from reaching their limits, we usually use between 10 and 50% of the capacity of the same (depending on the habits of each driver).At the moments of maximum mechanical requirement of the brakes, these can be excessively heated and once the brake capacity is transpassed beyond 100%, the brakes lose their effectiveness and their performance can fall into picks.
It’s when we already have to propose a change in the braking system of our car to improve it, if we don’t want to increase the braking distance and have a disgust.
When is it recommended to overdimension brakes?
Overall, it is advisable to overdimensional brakes in the following cases;
Increasing the power of our engine by more than 30%
When the power/weight ratio varies in the same proportion
When used high adherence semislick or slick tyres
- In general when we have a car intended to make tandas and/or trackdays.
Often we get queries from users who want to mount overdimensional brakes and don’t know the difference between the various options on the market.
To know more accurately what kind of kit and brand we have to mount is best always counting with the opinion of an expert who can guide us well, not osbtant, then we will give a few basic recommendations so that the user has a bit clearer what should mount.
To choose the most right option you have to explain before a little theory to know how the brakes work and behave.
Dynamics of the brakes
The need to mount a kit or another class will come conditioned primarily by the use we’re going to give and the average temperature we’re going to reach, the more we brake and the more intensity we do, it will generate a quantity of heat in the brake proportional to the temperature that the brake system will reach.
Starting from the premise that "energy does not create or destroy, it transforms," we know that a moving car possesses a kinetic energy and that to brake it within a space and time we will need to apply a brake force.
The kinetic energy in motion produced by the explosions or combustion of the engine turns into thermal energy when the brakes stop the car, the temperature that the brakes will reach will depend on how long we are pressing the pedal and the intensity of the force we apply on it in a proportional way, to more time and more pressure, more heat generated.
It is important that the brake disks have the ability to quickly evacuate the heat accumulated in them between brake and brake, if we don’t stop braking and continue producing heat continuously, it will come a moment that the material will overheat too much, will not endure and break.
Therefore, the braking habits of each driver directly influence the duration and effectiveness of the materials.
All friction materials used in a brake system have a thermal capacity that depending on the materials used, will be greater or lower, the final price of the product is also a direct factor as a result of the materials used.
The original brakes are manufactured with a standard steel material, like the brake of brake pills, for cost issues, originally pieces are mounted that are designed to endure a cold emergency brake, but if a continuous use is made the brakes are thermally tired and the effect known as fading is produced.
Because each driver has a different braking habit, the maximum average temperature that will be achieved can vary notably from one driver or driver to another.
The ideal thing would be to know the maximum temperature we reach usual, but as we do not have the telemetry measurement systems that use professional racing teams, in general lines we can guide ourselves by the following orientative baremo:
Temperature brakes
The values in this table are approximately, from temperatures above 400 oC the original equipment brakes are when they begin to get tired and lose efficiency.
We can estimate that we are about 600 oC when at the maximum point of the final braking the disc acquires a slightly incandescent red color, 700 oC when the tonality is a more pronounced cherry red, 800 oC if the tonality is a more live incandescent red, 900 oC if it is an orange red.
From 1000 oC the tonality is a very live orange throwing yellow, racing cars move in these temperatures ranges, in these cases only carbon brakes endure these temperatures are the ones that are used for example in Formula 1the prices are astronomical.
There are several brands and different prices on the market, for which do I choose?
Strictly touching the overdimensional brakes (greater disks and pinces) there are several brands on the market, Galfer, Vmaxx, D2 Racing, K-Sport, AP Racing, Stoptech, Brembo, G-Force, Yellow Speed... among others.
To be sure we don’t get short in our choice we have to guide ourselves with the previous table and if we have doubts between one range and another it’s always better to go up to the top, better than over that not that fails.
AP Racing and Brembo:
Advised for high-level competitions and high-performance sports vehicles.
The brands Brembo and AP Racing are the most well-known and used in the competition world, they are the best brands in terms of quality and performance, the only stick they have is that the prices are very high and a brake kit for each axis is not below the 3000 euros.
Normally they are recommended in high-end super-sport and hyper-sport cars such as the AMG versions of Mercedes, Ferrari, Porsche GT3, Nissan GTR, Aston Martin Vantage, Audi R8.etc
K-Sport and D2 Racing
Tands and track days in circuit for compact vehicles and high-end tourism and power up to 500 cv.
Examples: BMW M3 & M5, Audi S3 & S4, Nissan S13 & S14, Subaru Impreza, Mitubishi EVO, Civic type R, Alfa Romeo GTA, Focus RS, Supra, Golf GTI & R32..etc
If you’re not going to use our car in competition and if our budget does not allow us, there are other very interesting options on the market such as K-Sport and D2 Racing with an excellent balance between performance and price.
VMaxxThe
The brake kits VMaxx it is recommended for sport driving on the street, mountain and occasional circuit tandas, and in those cars in which the user wants to improve the braking of the original equipment without spending a lot of money.
Only are manufactured in diamonds 290 and 330 mm with 4 pistons pinces, indicated for tourism and compact medium range or medium/high up to 200/250 cv
Otras marcas the low cost:
In general, any fat brake kit that is on the market below the 900 euros is not a guarantee that we have a good response on the brake, since the quality of the materials can be mediocre and can be tired in efforts not very high even before the original equipment, unless the intention is merely aesthetic or posture.
Quality D2 Racing Guaranteed
Many are the users who already enjoy the quality and performance of the brake kits The D2 Racingdespite the good quality/price ratio The D2 Racing providing in their products, some users still have doubts about their effectiveness.
It is not surprising when the first brands of the competition see their hegemony in the market, it is when rumors appear that the kits The D2 Racing they are of medium quality, which break and/or double discs, etc
To dissipate the possible doubts that may be about your brake kits, The D2 Racing he has elaborated a very illustrative video in which some discs submit to an extreme effort The D2 Racing and one of the competition of medium quality.
Pay special attention to the video end at the right brake
The D2 Racing it supplies high performance brakes to professional competition teams and among its brakes stand out carbon brake disks and titanium monoblock pinces.
Overdimensional brake kits The D2 Racing
The kits The D2 Racing it consists of the following elements:
- Game of 2 pinces monoblock (optional street or sport)
- Game of 2 discs (optional rolled or perforated) of 2 pieces with aluminum nuclei
- Optional fixed or floating disc system (the floating system has recharge)
- Game of 2 Pins
- Game of 2 metals reinforced
- Game of 4 pills street specifications (optional extra game of pills Racing)
- Game of Tornado
- Instructions of assembly
The kits The D2 Racing there are two types of pinces:
Street Calipers
With 6 pistons for 286/304 mm discs and 8 pistons for 330/356/380/400/421 mm discs.All with guard-polled retentions on the pins.The manufacturer gives a 2-year guarantee for these kits against manufacturing defects.Its use is recommended for street cars.
Sports Calipers
With 6 pistons for 286/304 mm disks and 8 pistons for 330/356 mm disks.Do not carry guard-polls on the pins.The manufacturer gives a 1 year guarantee for these kits against manufacturing defects.Their use of advice for competition cars, the brakes in racing cars reach very high temperatures, therefore they are mounted without retentions to prevent burning.In contrast, they need much more frequent cleaning maintenance.
Characteristics of brake kits
- Overdimensional brakes The D2 Racing they are high-performance brakes specially designed to provide a brake much higher than the original car equipment brings.
- All records are incorporated nucleos of aluminium to better evacuate the heat, minimize the heat conduction to other mechanical organs, such as palliers, cojinets, mangoets, bulbs, etc
- The kits The D2 Racing they are compatible with use of other pills brake known as AP, Pagid, Ferod, Hawk, Mintex, EBC, Carbon metallic etc.
- It is a monoblockthey are made of a single piece to reduce weight and increase structural resistance and eliminate deformations practically.
- The colors of the brake brakes arered, orange, yellow, blackif you want another color, they can be customized but the delivery time will be higher and there will be an extra charge for paintwork.
- ORptionally disc can be chosen perforated or ranched (option to choose in the shopping cart)
- The anchors of the pistes to the aluminum nuclei of the kits with disc diamonds of 286 and 304 mm by default serve as a fixed union system, while for the 330 and 356 diamonds you can choose optional fixed or floating system (the floating system is better but also more expensive) and for the 380 diamonds, 400 and 421 mm are all served with default floating system.
- The predetermined compound of the brake pills served in the kit is a the Standard Street for everyday use and to ensure cold emergency brakes, if you want pills with a circuit racing compound, we recommend acquire an Extra Game of Pills with Compound Racing in the shopping cart options.
- It is not only recommended but practically imperative use Racing pills on circuit tandas if you’re going to use high adherence tires (semislicks and slicks).Otherwise, the pills can be disintegrated.
Features of monoblock pinces
- More compact and lighter than double body pinces.
- Manufacturing with CNC methods with very advanced machines, computers and software that requires a very concrete specialization.
- Increased structural resistance that practically eliminates the likelihood of deformation.
- It allows you to have a brake pin longer than conventional brakes
- Design and finish of great quality with the incorporation of racing logos with carbon fiber look.
- Brands like Brembo offer monoblock forged pinces only for high-end sports models in GT3 racing versions such as for example Ferrari, Lamborghini, Audi R8 etc.The cost of these kits in brands like Brembo and AP is usually astronomical, The D2 Racing it offers this technology throughout the catalog of its kits and also at affordable prices for all those users who wish to mount a heavy Sport or Racing brakes kit in their tandas and/or track days but without having to make an excessive refund.
Use of brake kits The D2 Racing
The origin-montered brakes in the first equipment of the cars, are designed to work within certain parameters, specifically to provide a high freezing coefficient of the freezing in cold to stop the car as soon as possible with a relatively low usage temperature.
These brakes are prepared to perform emergency brakes, as much two or three times in little space, but if a continuous use of them then the temperature of these increases and cause a fatigue and a strong performance fall known as fading.No matter how strong we stop, the car will cost you a lot to stop.
On the other hand, heat is generated by the friction between the pill and the disc, transmitting to the piston of the calipers and from there to the brake liquid, which in normal conditions is incomprehensible, but when it reaches the ebulation temperature, gas bubbles appear, and the gas is compressible, causing a drop in performance.
The brake kits The D2 Racing they are designed to absorb, ventilate heat and delay the appearance of fading as much as possible when an extreme use is made in sports driving and delay the braking limits far beyond the conventional brakes.
Important is:
It is recommended to choose the same disc diameter for the front and rear axis to ensure a correct braking distribution, the kits The D2 Racing the share ratio is 7/3.
It is recommended to check the alabeum of the old bulbs and the state of the rollingsif they are in bad condition, they can the appearance of vibrations on the brakes (the manufacturer’s warranty covers defects of material manufacturing, but not of vibrations caused by this cause).
It is also advised to apply for a self-test template before confirming the order to verify that the disks and bricks will have enough location space on the bricks that your vehicle currently carries and to make sure they will not interfere with them.If the brakes touch for carrying a plate different from the original, the seller is not responsible.
Always maintain proper cooling from the brakes to ensure their effectiveness, if no air comes they can be overheated. NEVER MOVE DOWN ANY CONCEPT OF THE FREES IN CALM.
This type of brakes are designed for sports driving and not for their normal everyday use, the use that is made of them is the responsibility of the user, at greater demands of the brakes in such as, for example, driving in circuit tandas, greater waste of the pills.The wear of the pills in this type of brakes increases exponentially compared to the original brakes. In the case of tandas and track days on the circuit, it is always recommended to check the waste of the pills before each tanda.
The ITV’s
These brake kits are designed to greatly improve the brake of vehicles with respect to the original equipment brake system.The assembly of a overdimensional brake kit is considered in most ITV stations as a reform of importance that has to be legalized.
It is the responsibility of the user to introduce important reforms in his vehicle and not the manufacturer or seller that supplies the material.If you want to use these components for use on the street, and you’re wondering if your car will pass the ITV or not with them, we recommend you consult at your usual ITV station if they’ll allow you to pass the inspection or they’ll force you to legalize the reform.The seller cannot answer this question because the ITV stations of each autonomous community work independently when following the protocol of the reform regulations.
Legalize your brake kit with BBSport to pass ITV without problems
Depending on the interpretation of the ITV reform regulation that is made in each autonomous community, it is possible that the incorporation of overdimensional brakes kits is typed as a reform of importance, depending on the inspector who performs the inspection.
In our company BBSport we can process the reform legalization process so that you don’t have any problems and pass the 100% guaranteed ITV.
