What is a Big Brake Kit?

Go fast and stop faster. D2 Racing Big Brake Kits provide you with serious braking power when you need it most.

We know that braking performance is linked to the surface area the brake pads have to bite into. So larger pads and larger brake discs are perfect for shorter stopping distances. This increase surface area helps the heat dispersal, as heat is the enemy of braking performance.

The number of pots of the calipers will also play a role in term of pressure applied on the pads to make the contact as good as possible on the rotors. In order to fit the caliper on your original chassis, D2 Racing provides caliper brackets to position the calipers with your new braking system, making the perfect set up for your car brakes system.

Our brake kits are offered for both the front and rear with rotor sizes ranging from 286mm-421mm, 4-8 piston aluminum caliper options, and custom colors. Stainless steel brake lines, brake pads, and hardware are included for a bolt-on installation.

D2 Racing calipers are precision machined from aircraft quality billet aluminum and feature heavy duty aluminum pistons mated to temperature resistant seals. These high performance calipers are able to utilize a lightweight construction while providing dramatically increased braking performance. The rotors included in our big brake kits feature a two-piece design and slotted surfaces which help minimize fade and dissipate heat under the most extreme braking conditions.

Frequently asked questions

How can I know if a Big Brake Kit will fit on my wheels?

Minimum size required is 15” but that will depend on the kit you selected. First make sure to select your car, and depending on the size you selected, you can contact us. We will provide you a drawing for the caliper clearance requirements.

Why is the rotor break-in procedure of the pad and rotor so important?

This is technical to maximize braking performance. If this procedure is not done correctly, it can cause damage to the rotors and adversely affect overal braking performance. Rotors and pads interact with each other to provide efficient brake performance. The break-in or bed-in procedure is done to condition the pad/rotor interface. Depending on the pad used, more or less pad material is uniformly transferred onto the disc as a thin film. The resins and bonding agents in some pads need to be heat cycled to work properly as well. By not properly bedding in pads, uneven pad material deposits can occur that may cause a vibration. Improper wear characteristics may also show up on either the pads, or rotors, or both, and both will wear prematurely. Always follow the recommended break-in procedure for any pads, rotors or brake systems.

Do I need to make modifications on my car to mount the big brake kit?

NO, D2 Big brake kits come with everything necessary to install the D2 kits. The installation of the entire big brake kit is almost plug and play, hardware is included as well. You will need to replace the existing caliper brackets that came on your vehicle and replace with our caliper bracket to mount the caliper on your vehicle.

Can I choose the color of my calipers?

Yes, you can select between: Painted purple, painted red, painted yellow, and anodized black. This will not change the price of the kits. Custom colors are also possible, you can contact us for more information

Should I choose Drilled or Slotted discs?

Below we explain the difference between drilled and slotted discs.

D2 Slotted discSlotted:
Slotted rotors offer improved bite (initial onset of braking) and slightly higher friction level than smooth rotors. Slots prevent reduction in friction due to pad outgassing or brake dust trapped between pads and rotors. Pad coefficient of friction is maintained over the lifetime of the pads, since slots shave away glaze formation and expose fresh pad surface each time brakes are applied. Slotted rotors are by far the number one choice for cars used in competition or open track events. Disadvantages include slightly reduced pad life, some low frequency rumble and pedal flutter when braking hard from high speeds.

D2 Drilled discDrilled:
Drilled rotors offer slightly more bite and friction than slotted rotors. As with slotted rotors, pad coefficient of friction remains consistent over their lifetime. Wet bite is improved over plain and slotted rotors, so these may be the best choice for areas with heavy rainfall. Weight is reduced by about 0.2 pounds per rotor, depending on size and drill pattern. Disadvantages include possible uneven rotor wear, typically concentric groove formation, although this is mostly an aesthetic concern. A major disadvantage is accelerated formation and spreading of cracks under racing conditions. For this reason, drilled rotors should be avoided for track cars, unless required by the rules. A common piece of misinformation is that they have lower performance than smooth rotors, due to reduced surface area and are for looks only. This is false.

What are the differences between Race Pads and Sport Pads?

Pads are available in two variants:

  • Sport Pads (supplied by default): suitable for street use, good response when cold (steady friction coefficient of 0.46 to 0.53 up to 600 ° C).
  • Race Pads: Carbon /Ceramic with excellent temperature resistance, less bite when cold (steady friction coefficient of 200 ° C to 900 ° C)
