TR65 Water-Cooling Front 6-Piston Big Brake Kit
The TTSPORT TR65 Water-Cooling Front 6-Piston Big Brake Kit is built for sustained circuit abuse — endurance stints, time attack, and back-to-back hot laps where pad temperature, fluid temperature, and brake balance decide the result. A monoblock forged caliper with staggered 27 / 32 / 38 mm pistons works with a two-piece Ø355 or Ø370 mm vented rotor and integrated water-cooling routing to keep the friction window stable lap after lap.
Why Builders Choose the TR65 Water-Cooling
The TR65 Water-Cooling system is engineered for circuit, time attack, and endurance use where normal front caliper heat management can become the limiting factor. Water-cooling routing, a monoblock forged aluminum body, 50.10 cm² piston area, 36 mm-thick two-piece rotors, and racing pad options work together to keep pedal feel, friction behavior, and service life more consistent under sustained heat.
Staggered 6-Piston Layout
27 / 32 / 38 mm pistons distribute clamp load across the pad to even out wear and reduce taper at race temperatures.
Monoblock Forged Body
One-piece forged 6061-grade aluminum housing for high stiffness, low flex, and consistent pedal travel under load.
Two-Piece Rotor Platform
Ø355 or Ø370 mm × 36 mm two-piece rotors with fixed or floating mounting depending on rotor size and chassis.
Pad Window for Racing
Standard 0–600 °C / μ 0.38 pads, or racing 0–750 °C / μ 0.45 pads for sustained pro-am use.
Serviceable Track Hardware
Replaceable rotor rings, rebuildable seals, radial-mount brackets, vehicle-specific braided lines, and required bedding workflow.

The Bespoke Engineering Process
Every TR65 Water-Cooling front circuit racing system is engineered around the vehicle’s front knuckle, hub location, rotor hat offset, wheel barrel, spoke clearance, brake line routing, water-cooling line routing, front brake bias target, rear brake pairing, suspension package, and competition class. The goal is not a generic universal fit; the goal is a water-cooled front brake package that works with your chassis geometry and keeps friction behavior stable across sustained circuit heat.
1. Technical Consultation
We review the chassis, front suspension and knuckle setup, motorsport use, target front brake behavior, wheel package, tire compound, rear brake pairing, cooling-line packaging, competition class, and whether the car uses OEM or custom front uprights.
2. Data Submission
For OEM knuckles, provide chassis, year, wheel specs, suspension layout, target use, and available cooling-line routing space. For custom uprights, motorsport hub conversions, or non-OE rotor offsets, provide CAD files, technical drawings, hub-face data, rotor mounting dimensions, water-cooling routing constraints, or accurate bracket mounting-point measurements.
3. Engineering Review & Approval
TTSPORT confirms rotor diameter, vehicle-specific caliper bracket geometry, rotor hat offset, wheel clearance, brake line fittings, cooling-line routing, pad compound, and pad-to-rotor alignment before production begins.
If you are unsure whether your wheel, front knuckle, hub geometry, rotor offset, cooling-line routing, rear brake pairing, or competition layout is suitable, Contact us before ordering so the engineering team can review the build details.
Installation & Break-In
- Every TR65 Water-Cooling kit ships with vehicle-specific radial brackets, rotor hat offsets, and braided lines matched to the caliper-side and chassis-side fittings.
- Water-cooling line routing must be confirmed against wheel barrel, suspension travel, steering angle, upright geometry, and service access before production.
- Choose Ø355 × 36 mm rotor for lighter rotating mass and faster heat-up in sprint races, time attack, and lighter chassis.
- Choose Ø370 × 36 mm rotor for more thermal capacity and leverage in endurance, heavier cars, and high-downforce setups.
- Standard Steel uses proven high-carbon iron for club racing and HPDE.
- Racing Steel uses uprated heat treatment paired with the 0–750 °C / μ 0.45 pad for sustained pro-am use.
- Racing pistons without dust boots are intended for motorsport use and require regular inspection between sessions.
- Bedding-in is required before track use to transfer pad material to the rotor face evenly and stabilize friction performance.
Frequently Asked Questions
Is the TR65 Water-Cooling kit street-legal or track-only?
This kit is engineered for circuit, time attack, and endurance use. Racing pistons run without dust boots and use racing compounds. It can be driven on the road for transit, but it is not optimized for daily use or cold-bite scenarios.
Which rotor size should I pick — 355 mm or 370 mm?
Choose Ø355 × 36 mm for lighter cars and sprint sessions where rotating mass matters. Choose Ø370 × 36 mm for heavier chassis, endurance stints, or high-downforce setups where thermal capacity is the priority.
What is the difference between Standard Steel and Racing Steel rotors?
Standard Steel uses heat-treated high-carbon iron suited to club racing and HPDE. Racing Steel uses a racing-grade heat treatment paired with the 0–750 °C / μ 0.45 pad for higher sustained temperatures and tighter μ stability.
What wheel size do I need to clear the calipers?
18-inch wheels or larger are required. Final clearance depends on wheel face design, offset, spoke profile, rotor diameter, bracket package, and water-cooling line routing. Send wheel specs and TTSPORT will verify before shipping.
Do I need a specific bedding-in procedure?
Yes. Bedding-in is required before track use to transfer pad material to the rotor face evenly. The procedure ships with the kit. Skipping it will compromise pad life and friction stability.
Can you build this kit for my specific chassis?
Yes. TTSPORT engineers radial brackets, hat offsets, cooling-line routing, and braided lines to the vehicle. Contact the team with chassis, year, wheel spec, suspension layout, and intended use so fitment can be confirmed before production.

Soft, Stylish Leopard Blanket That’s Lightweight, Cozy, and Big Enough to Share
I have been using this leopard print blanket on both the bed and the couch, and it hits a really nice balance between style, size, and comfort. I went with the larger twin style size instead of a small throw, and that was the right call; it is big enough to fully cover me when I am lying on the couch and works much better for two people sitting side by side than a standard throw that always feels a bit cramped. It also looks great draped across the end of a bed or over the back of a sofa, so it doubles as decor.
The leopard pattern is genuinely attractive in person. Up close you can see that it is a printed, short shag/flannel style rather than true faux fur, but the brown leopard version still reads more realistic and intentional than a lot of loud, pink “leopard” prints. The colors are vibrant and have a nice pop without being tacky, so it fits easily into different rooms and color schemes as a fun accent. From a distance, it gives a soft, faux fur vibe that looks more expensive than it is.
Comfort wise, it is very soft and pleasant to snuggle with. One side feels just slightly softer than the other, but both are smooth and cozy against the skin. It is a single layer blanket with rolled and stitched edges, so it is not a super thick winter comforter, but that actually makes it more versatile. It provides enough warmth to feel comforting without being overly hot, which makes it a nice year round piece: cozy in cooler weather with an extra layer, and just right on its own in milder seasons.
The blanket is also lightweight, which makes it easy to move around the house or pack for travel, while still feeling substantial enough that it does not come across as flimsy. It has held up well so far, and the overall quality feels good for the price, especially given the larger size. If you love animal prints and want something that works as both decor and a genuinely comfy blanket to curl up with, this one is easy to recommend.
Pros:
Large twin style size is big enough to fully cover an adult or share on the couch
Soft, plush flannel style fabric that feels cozy against the skin
Lightweight but still warm enough to be comfortable year round
Brown leopard print looks stylish and more realistic than many novelty patterns
Colors are vibrant and work well with a variety of room styles and palettes
Edges are neatly rolled and stitched, giving it a clean finished look
Cons:
Single layer construction means it is not as heavy or insulating as a thick winter blanket

Super Cozy & Stylish – My New Favorite Throw Blanket
I recently got this brown leopard print throw blanket, and it quickly became one of my favorite cozy essentials at home. The first thing that stood out to me was the trendy animal print design—it adds a bold, stylish touch to my living room and makes my couch look instantly more put together.
The material is incredibly soft and plush. It has that fluffy flannel feel that’s perfect for snuggling, whether I’m watching TV, reading, or just relaxing. It’s warm without being too heavy, which makes it great for using all year round.
I also really like the size (60" x 80")—it’s big enough to fully wrap around me or share when sitting on the couch. It works just as well on the bed as it does as a decorative throw.
Another plus is how lightweight and easy to carry it is. I’ve even taken it along for road trips, and it’s been perfect for staying comfortable on the go.
If I had to point out one small downside, it’s that lighter-colored fabrics can show wear over time if not cared for properly, so I make sure to wash it gently to keep it looking fresh.
Overall, I’m really happy with this blanket. It’s the perfect mix of comfort and style, and it adds a cozy, fashionable vibe to any space. Definitely a great pick if you love soft textures and bold décor!

Soft, Warm, and Holds Up Well After Washing
We grabbed this primarily for couch lounging and it has been a regular rotation blanket since it arrived. The softness is legitimate, not the kind that feels good out of the packaging and then stiffens up after a wash or two. It has gone through the machine multiple times and both the texture and the leopard print have held up without fading or pilling. The 50 by 60 inch size is a comfortable fit for one person stretched out on the couch.
It is warm without being heavy, which makes it practical across seasons rather than just winter. The print looks sharp and adds some personality to a living room without being over the top. For a throw blanket at this price, the quality is better than expected and it has earned a permanent spot on our couch. If you are looking for something soft, visually interesting, and durable enough to actually use regularly, this one delivers.

Pretty good blanket. Slightly larger than normal throw.
I purchased this leopard print throw blanket because you can get it in twin size and twin size is a lot more usable in not only a bed but also on a couch. Like if you have two people sitting next to each other, it's a lot easier to use the twin size than a throw size, which I feel is a little bit cramped.
In addition to that, I saw in the picture that this looked almost like fur. Now when you look at it in person, you can clearly tell it's not for it's got almost like a a spotted pattern even with the spots. And while I don't know if leopards actually look like that, certainly at a distance, it feels a lot more accurate than things that are only vaguely leopard printed like the the common pink ones, as you can see here in the other variety. But certainly the Brown leopard one looks good.
Plus, it is comfortable and pretty soft. It's softer on one side than another side, but only slightly and while it's rolled over and stitched at the edges, it is a single layer throughout. So it's not going to give you a ton of warmth. But I will give you some warmth, you know just enough to be nice and that means you can use it year round.
So overall at this price for a twin size leopard print throw. I think this is a good deal. Well I think it could be a better deal. I've certainly seen worse so I think I could recommend this product
