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

Works well!
Style: 16 oz
This stuff works well. I've only ever used it after my tires had been punctured and ran flat... I haven't had a flat this wouldn't seal... 3 uses so far all 3 have fixed flats and been many miles put on since the repairs. I start with as little as possible and if it doesn't seal I just add more, I think I've managed to use far less than recommended and successfully sealed punctures. I've only used it on fat tire e-bike tires. I'm pretty comfortable with the seal and I have no plans to replace the tubes, which saves me a fair amount of trouble. I will update if it springs any leaks without new punctures. It's very easy to use and actually pretty clean especially compared to automotive type tire repair foams. The first repair I used it for was a brand new bike that just wouldn't hold air in the rear, totally unsure what caused it to keep losing air but 2 or 3 small doses of slime fixed it. The most recent slime repair, I had a wobbly bike ride which felt weird and I couldn't figure out why but a few hours after I had returned home both tires were totally flat. They both had a handful or more of some really heavy duty thorns stuck in the tire that likely barely punctured the tubes but the rear tire also had a roofing nail in it. I did not think the slime was going to fill that one, it was a pretty heavy leak once I removed the nail, but Slime did seal it and I've since ridden the bike twice and in the same rough conditions I normally would still holding strong at higher pressure than I normally ride, have yet to drop back down since refilling but I am hoping and expecting it won't be a problem. Two thumbs up. I always keep a small tube in my bike bag and I am confident if I ever need it while I'm out and about it will be useful.

Who can live without slime great stuff and a good price. 👍
Style: 32 oz
If anyone has an outdoor anything that takes air. You should never be caught without this stuff. It seals your tires on almost anything and it lasts longer than you would expect. It’s easy to use and easy to clean up after using it. It will work well for anything that is supposed to hold air. Great product.

Title: Reliable, Easy-to-Use, and Worth Every Penny
Style: 32 oz
I’ve been using Slime tire sealant for my fat tire e-bike, and I can say with confidence that this product delivers exactly what it promises. The application is simple, the results are consistent, and the peace of mind it provides is invaluable. For anyone who rides regularly — whether for commuting, recreation, or deliveries — this is a product that pays for itself many times over. The first thing I appreciate about Slime is how easy it is to install. The bottle is well-designed, the instructions are clear, and the process takes just a few minutes. You simply deflate the tire, remove the valve core, squeeze in the recommended amount, reinstall the valve core, inflate, and spin the wheel to distribute the sealant evenly. No special tools, no mess, and no guesswork — just a straightforward, user-friendly process. Performance-wise, Slime does exactly what it’s supposed to do: seal punctures quickly and effectively. I’ve had nails, thorns, and sharp debris puncture my tires while riding, and in every case where the leak was within the tread area, Slime sealed it instantly. There’s something incredibly reassuring about hearing that faint hiss of air for a second, then watching it stop as the sealant does its job. It’s a real-time reminder that this product is actively protecting you from being stranded. What sets Slime apart from other sealants I’ve tried is its durability. Once applied, it stays active inside the tube for months, ready to respond to new punctures as they happen. It doesn’t dry out quickly, it doesn’t clump up, and it doesn’t cause balance issues with the tires. For someone who rides almost daily, that reliability is a huge plus. Another thing I respect about this product is that it’s non-toxic and environmentally friendly. If a bit of sealant escapes during a repair, I don’t have to worry about it harming the environment. It’s also water-soluble, making cleanup easy if I ever need to replace a tube or tire. That attention to safety and sustainability shows that the company isn’t just making a great product — they’re doing it responsibly. The value for the price is excellent. One bottle goes a long way, and when you factor in the cost of replacing tubes, paying for roadside repairs, or even the inconvenience of being late because of a flat, Slime is an investment in both savings and peace of mind. For delivery riders like me, it’s especially valuable — every flat avoided means another day of work uninterrupted. In short, Slime is one of those rare products that I can recommend without hesitation. It’s easy to use, effective, long-lasting, and backed by a company that clearly understands the needs of cyclists and e-bike riders. It has already saved me from countless headaches, and I plan to keep a bottle on hand at all times. If you ride regularly and haven’t tried it yet, you’re taking an unnecessary risk — this is one of the best preventative tools you can add to your maintenance kit. Verdict: Five stars for performance, ease of use, and overall value. Slime is a must-have for any serious rider who values reliability and wants to keep rolling no matter what’s on the road.

Slime is good, pump is a disaster
Style: 1 gal, Style: 1 gal
The only reason I am giving this a 4 star(not zero) rating is the slime itself. The actual pump on the 1 gallon canister is awful. It makes so much mess, so I do not know whether I pumped the slime into the tubes or it all just spilled out of the base of the pump. The bottles worked great, but this time I needed to use more slime for a bunch of tires. What a slimy mess that was. Very poor pump design. Only after I spilled who knows how much of the slime, I finally washed it and was able to see the problem. The cap at the base of the pump got unscrewed and let all the slime lose. I screwed it back up and this should fix the mess next time I use it. Just a heads if someone encounters the same issue.
