4 Piston Front Big Brake Kit Fixing 304x28 D2

IMPORTANT! When purchasing, please provide additional information in the order notes, such as: car model, car type (Street, Sport, Racing) and caliper color (purple, yellow, black, green, red). After placing your order, our staff will check availability and confirm the shipping price.

D2 Racing Big Brake Kits offer unrivaled stopping power. The clamps are available in purple, black, yellow and red.

Hollow sports clamps are made of aluminum using a monoblock forging process to achieve an even grain structure. Then CNC 3D technology was used.

The calipers are characterized by reduced weight and very good heat dissipation, which effectively reduces brake temperature and increases braking power.

The clamps have a hot-pressed carbon manufacturer's logo.

Set contains:

  • 2 x ventilated discs with slots or holes, with aluminum bells (compatible with all OEM separate handbrake systems, drum, electric, etc.)
  • 2 x forged aluminum monobloc brake calipers.
  • 2 x braided brake lines.
  • All required mounting hardware (brackets, screws, instructions, etc.).

1 x set of brake pads for your choice:

  • Street (Resistant to temperatures up to 600 degrees)
  • Sports (Resistant to temperatures above 600 degrees)
  • Racing (Resistant to temperatures up to 1000 degrees)

Please remember that the clamps will be larger than standard ones and refer to the table below before choosing the clamps:

Minimum wheel size (inches) Disc Size(mm)
15 286
16 304
17 330
18 356
19 380
20 400

Differences between slotted and drilled brake discs:

Notched:

In slotted brake discs, small recesses (four to eight evenly distributed) are typical, milled on the surface of the brake disc.

Grooves provide the same cooling benefits as holes, but with less risk of separation and gapping because the grooves do not typically extend over the entire surface of the rotor (although there are some designs on the market today).

The grooves are usually oriented and curved so that they can cover the entire surface of the brake pads, providing much better ventilation than a series of holes. The condition of the brake disc can be assessed based on certain types of cuts.

The grooves also create a "shave" effect that keeps the surface of the brake pads cleaner for better steam contact.
In addition, the presence of cuts works like a grater, increasing the car's braking efficiency.

At the same time, you should be aware that the wear of the pads increases. In order to avoid rapid abrasion, it is recommended to select high-quality pads for such discs.

Drilled:

Drilling 30 to 40 evenly spaced holes in the brake discs improves air ventilation and cooling effect.

The holes actually had an unexpected benefit. They created channels for the extraction of hot gases emitted by the brake pads. Phenolic resins, which are used as a binder to connect brake pads, emit steam when heated excessively. The gas can form a boundary layer between the pads and the brake disc, which reduces friction.

In our case, the boundary layer of gas between the surface of the pads and the brake disc prevents the pads from connecting with the brake disc, reduces friction and braking force, just at the moment when the driver needs it the most.

If the brake disc is perforated or has slots, holes or grooves that separate the boundary layer and allow gas to escape, then the pads can make full contact with the brake discs. In addition, holes and grooves help remove dust and dirt that gets into the space between the brake disc and pads.

At a microscopic level, dirt between the pads and the brake disc can reduce the couple's contact area. Naturally, this also reduces friction and equipment efficiency. Therefore, the holes, while helping to remove dust and dirt, provide the pads with the ability to maintain maximum surface contact.

Other information:

  • D2 Racing calipers are machined from aircraft-grade aluminum, and the pistons mounted in them have very high temperature resistance (tested up to 1,000 degrees Celsius).
  • D2 Racing managed to keep the caliper's weight low while providing significant improvements in braking power.
  • There is a carbon D2 logo on each clamp.
  • 5-year warranty against leaks and 10 years against cracks and deformation
  • TUV and ISO9001

The Best Affordable Twin Bed Frame
Size: Twin, Style: 14 Inch ( Non - Foldable), Size: Twin, Style: 14 Inch ( Non - Foldable)
I’m honestly so impressed with this twin-size metal bed frame. I was looking for something affordable but still sturdy and safe for my toddler, and this checked every box. Assembly was super simple, I put it together by myself without any stress, which is a huge win. The frame feels solid, doesn’t squeak, and gives me peace of mind knowing my little one is sleeping safely. It’s also a great height, not too high, not too low, making it perfect for a toddler transitioning into their own bed. For the price, the quality really exceeded my expectations. If you’re looking for a budget-friendly, easy to assemble bed frame for a child, this is definitely worth it!

Great frame for a pinch!
Size: Full, Style: 18 Inch ( Foldable)
Needed foot surgery and was in need of a frame that I could assemble quickly on my first floor since I was having foot surgery in 2 days. Arrived quickly, unfolded the 2 pieces, connected the two frames together with 2 wing nuts. Assembly took 5 minutes. Super simple! It seems sturdy and the 18 inch frame is high enough to allow me to stand from it on one leg. Great buy!

Sturdy, Affordable and Easy To Set Up
Size: King, Style: 18 Inch ( Foldable)
This was so easy to set up and is super sturdy! It has transformed my bedroom! I was able to stack multiple storage containers under the bed, add an extra long bed skirt and walaa! My favorite part is that my mattress is no longer sinking in spots where the boxsprings were faulty. My 13 yr old and 16 yr old had this set up for me in under 30 minutes. My husband is 6'3" and 180 lbs. I was hesitant thinking we would break the bed within a week but it has upheld!!!

Mixed feelings so far
Size: Queen, Style: 14 Inch ( Foldable), Size: Queen, Style: 14 Inch ( Foldable)
**TWO MONTH UPDATE: overall I still like the bed frame. I appreciate the ample amount of storage underneath the frame, to put stuff underneath when company comes and you need to stash stuff out of sight. The frame does wiggle a lot with any extra activity, but that's kind of expected with a foldable frame I suppose. *INITIAL REVIEW: I will update this review in a few months, after several rounds of overnight visitors have used this queen size frame and a 6" foldable foam mattress. I think this will be a good purchase and offer a better night's rest than the air mattress I was previously using for company. PROS: - very simple setup and take down - easy to store away, not bulky - nice height off the ground to help my guests feel comfortable and easily get in and out of the bed - appears to be a sturdy frame made (I will update after a few months of use) - fast, free shipping CONS: - arrived with scuffs on the frame - a lot of the metal mattress supports are not straight, indicating poor craftsmanship, but time will tell - made in China - scoots across wood floor easily, so if you're planning to use on hardwood floors you may want to add those rubber pads to the bottom of the legs to prevent it from sliding when you get in and out of the bed - the two bolts that connect the two frames together (queen size frame) might get lost, it would be cool if they were attached somehow, but for now I'm just keeping them bolted to one frame while in storage.

Good quality! Lots of storage underneath.
Size: King, Style: 18 Inch ( Foldable), Size: King, Style: 18 Inch ( Foldable)
We’ve had it for about a year now. It’s very tall, supports the mattress well, and is good quality for the price. It’s easy to put together and survived our first move great. There’s not a lot of squeak with movement. Overall good purchase with good delivery and easy to put together.
