TR60 Front 6-Piston Big Brake Kit
The TTSPORT Circuit Racing TR60 is a front-axle, 6-piston monoblock big brake kit engineered for circuit work — repeatable stops lap after lap, a wide pad operating window, and a serviceable platform built around a forged aluminum caliper and two-piece floating rotors.
Why Builders Choose the TR60
The TR60 is a Racing Series — Circuit caliper aimed at lapping cars, time-attack builds, endurance programs, and heavy track-day use. Six staggered pistons, 27 / 32 / 38 mm, deliver even pad loading across the full pad face, reducing taper wear and keeping bite consistent as pad temperature climbs. Monoblock forged construction resists caliper flex under high line pressure, so pedal feel stays firm deep into a stint.
6-Piston Monoblock Caliper
Monoblock forged aluminum body with 50.10 cm² total piston area per caliper for stiff, even clamp under high line pressure.
Staggered Piston Layout
27 mm × 2 / 32 mm × 2 / 38 mm × 2 pistons support even pad pressure and consistent bite as pad temperature climbs.
Two-Piece Rotor Platform
Ø355 or Ø380 mm × 32 mm two-piece rotors, internally vented, with fixed or floating mounting depending on rotor size and vehicle application.
Standard or Option B Pad Window
Standard 0–600 °C pads for HPDE and sprint use, or Option B 0–750 °C pads for endurance, time attack, long stints, heavy cars, and aero builds.
Track-Service Platform
Racing pistons without dust boots, serviceable seals, replaceable friction rings, and stainless braided lines support long-term track use.

The Bespoke Engineering Process
Every TR60 front circuit racing system is engineered around the vehicle’s front knuckle, hub location, rotor hat offset, wheel barrel, spoke clearance, brake line routing, front brake bias target, rear brake pairing, and intended motorsport use. The goal is not a generic universal fit; the goal is a front brake package that works with your chassis geometry and delivers repeatable pedal behavior lap after lap.
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, downforce package, and whether the car uses OEM or custom front uprights.
2. Data Submission
For OEM knuckles, provide vehicle information, wheel specs, and intended use, including sprint, endurance, drift, or rally. For custom uprights, motorsport hub conversions, or non-OE rotor offsets, provide CAD files, technical drawings, hub-face data, rotor mounting dimensions, or accurate bracket mounting-point measurements.
3. Engineering Review & Approval
TTSPORT confirms rotor diameter, vehicle-specific caliper bracket geometry, rotor hat offset, brake line fittings, pad compound, and bedding requirements before production begins.
If you are unsure whether your wheel, front knuckle, rotor offset, rear brake pairing, or brake line routing is suitable, Contact us before ordering so the engineering team can review the build details.
Installation & Break-In
- Brackets, rotor offset, and line fittings are matched to your chassis.
- Send your vehicle, wheel spec, and intended use, including sprint, endurance, drift, or rally, before production.
- Choose Ø355 mm for lighter or smaller-wheel platforms where clearance matters.
- Choose Ø380 mm for heavier or faster cars that need more thermal mass and leverage.
- Standard 0–600 °C pads suit HPDE and short sprint sessions.
- Option B 0–750 °C pads suit endurance, time attack, and aero cars where pad temperatures stay high for long stretches.
- Racing pistons without dust boots are intended for motorsport and track use, with regular inspection between sessions.
- A proper bedding-in procedure is required to transfer pad material evenly to the rotor face and unlock full friction performance.
Frequently Asked Questions
What kind of car is the TR60 designed for?
It's a front-axle racing big brake kit aimed at circuit, time-attack, endurance, and heavy track-day cars running 18-inch or larger wheels. Final fitment depends on your specific chassis and wheel offset.
Which pad compound should I choose?
The standard 0–600 °C pad with μ ≈ 0.38 suits HPDE and short sprint sessions. The Option B 0–750 °C race pad with μ ≈ 0.45 is better for endurance, time attack, and aero cars where pad temperatures stay high for long stretches.
Should I run 355 mm or 380 mm rotors?
380 mm gives more thermal mass and leverage for heavier or faster cars; 355 mm fits more wheel options and lighter platforms. The engineering team will recommend a size based on vehicle weight, power, tire, and event type.
Is this kit street legal?
The TR60 uses racing pistons without dust boots and track-focused pad compounds. It is built for motorsport and track use. We do not market it as a street kit.
Do I need to bed the pads in?
Yes. A proper bedding-in procedure is required to transfer pad material evenly to the rotor face and unlock full friction performance. Skipping bed-in causes judder and inconsistent bite.
Can I rebuild the calipers and replace just the rotor rings?
Yes. The TR60 uses serviceable seals and a two-piece rotor design, so friction rings can be replaced without changing the alloy hats — ideal for endurance programs and long-term track use.

Not all great stereo systems meet all the requirements for connectivity.
I want to go on record, the Onkyo TX-Nr7100 is an awesome choice for a stereo avr. Great connectivity, a warm sound quality, and many options for your audio sound choices. But, because it's base connectivity, as it applies to Bluetooth, I do not recommend to connecting a PC to it. Due to audio and video, data separation. The Onkyo, though an excellent stereo choice, has problems playing Youtube and other types of media, with built in audio and video playback. It defaults to the miniplayer, built into the system and is impossible to get rid of in these situations. I give this product 5 stars on quality and performance, but it was not made to connect to a computer. Stll, I recommend this AVR Stereo Receiver on its aesthetic look, sound, audio and connections and quality. Very important to keep this in mind for Computer and gaming console connection to this system.

Exceptional Home Theater Receiver with HDMI 2.1, Dirac Live & THX – Incredible Value
After researching extensively and using the TX‑NR7100 firsthand with a 5.1.4 Dolby Atmos setup, I’m thoroughly impressed by its blend of features, performance, and value.
Setup & Interface
The guided setup process is smooth and intuitive—Wi‑Fi setup, firmware updates, speaker configuration and HDMI mapping all work seamlessly. The on-screen menus are clean and accessible, though some deeper options may require a bit of navigation
With six HDMI 2.1 inputs and two HDMI 2.1 outputs, this receiver supports 8K/60Hz and 4K/120Hz video formats, along with VRR, eARC, and ALLM. This makes it ideal for gaming consoles like PS5 and Xbox Series X—performance is solid with no reported signal dropouts on the primary HDMI ports.
Audio & Sound Quality
Every channel delivers up to ~100 W into 8 Ω, powering immersive content such as Dolby Atmos and DTS:X with clarity and presence. THX post-processing adds dimension and scale, especially with cinematic soundtracks. Dirac Live room correction provides musical staging, precise imaging, cleaner dialog, and deeper bass—transformative for untreated or irregular rooms.
Streaming & Multi-Room
Equipped with AirPlay 2, Chromecast, Bluetooth (including aptX), and Sonos/DTS Play-Fi integration, streaming is flexible and robust. Spotify, Tidal, Pandora, TuneIn, and more are all supported. It even functions as a Roon endpoint with no signal issues when streaming high-res audio over Ethernet.
Build & Design
The front panel features a large green display, a straightforward volume dial, and basic controls. While the remote is functional, it isn’t backlit. The control app is usable but somewhat basic, making desktop Dirac calibration a better option for fine-tuning.
Pros:
Cutting-edge HDMI 2.1 support for 8K/60Hz, 4K/120Hz, VRR & eARC
THX Certified with immersive Atmos/DTS:X and IMAX Enhanced support
Powerful and convincing Dirac Live room correction
Versatile streaming ecosystem and smart assistant compatibility
Excellent price-to-performance ratio compared to peers
Cons:
HDMI glitches possible; best addressed via firmware updates and proper setup

Best deal and beautiful sound
I bought this one on sale to replace my old Pioneer VSX-1120-K 7.2 ch receiver which did not support 4K video and new Atmos sound profile. I would say, it was the best deal in this category since it offered 100 watts/ch , 9.2 ch, 8k/4k supported, and nearly 50% price cut when on sale! The sound quality is amazing, especially after using Dirac live to measure and auto adjust all speakers’ sound curves, making my home theater sound in a different level. The high is very clear but not harsh while the low is soft and nice punch. I also like the Onkyo App which helps to control the receiver in many ways. I can use it together with other online music streaming services app without touching the remote controller any more, very convenient! The only a small problem it has, is that it’s BD/DVD HDMI input sometimes does not work well with Amazon fire stick. It makes the firestick restart over again and again, so I have to use the other input such as game input to work smoothly with the firestick.
Update: I have had this receiver for more than a year now. I would say, I love it more and more! It not only supports 4K/8k video through HDMI, but also has so many listening sound models to choose from, and the App on smartphone is a very convenient tool. One of my favorite functions of it is the Dirac live function. I used to analyze the sound characteristics of each speaker, and fine tune the frequencies on them, making my home theater speakers up to a very high level, making every single sound frequency is in its best condition. This certainly compensates the shortcomings of certain sound frequencies in each speaker. Many times I just sat in my home theater listening to the music from Spotify without watching movie, and it was so joyful. I am changing the rate from 4 stars to five!

The basic set-up is relatively easy which was a big plus for me......
First let me start off by saying that I am not an audiophile. So, this review will not get into the weeds of the more complex settings this receiver is capable of. For example, the Dirac room measuring option. No way was I attempting to mess with that. Especially, after reading that some reviewers who actually have experience with Dirac found it could be confusing/difficult to set up. Besides I come from a previous Onkyo the TX-SR607 which had the AccuEQ Room Calibration similar to this receiver, so I used that instead with no issues. As far as hooking up the speakers it's pretty straight forward. If you have banana plugs, use them, seriously. I originally planned on using banana plugs but in order to save time I decided against that. But I wish I had taken the extra time to go with bananas because trying to thread the speaker wire into the speaker terminals is tedious, there not much room between the terminals and even me with my skinny fingers struggled a bit. Wish Onkyo designed their terminals side by side, but I think only Denon does that. Anyway, after all the speakers were connected (I'm currently using a 5.1.2 setup) and I connected my tv, Blu-ray player, CD player, etc., etc., I ran the AccuEQ Room Calibration, and I was good to go. I did change the some of the settings like speaker volume that AccuEQ has set but nothing major. I have noticed that I need to turn the volume up much higher on this Onkyo than on my previous one. What I mean by that is that on my previous Onkyo I would set the volume indicator at around 30-35 tops for movies. With this one it's more like 40-45, maybe how the volume is measured is different on this one. The sound is excellent for movies and music I have no complaints there. I have only tried a few of features so far like Airplay but will dig deeper into the manual (I downloaded from the internet) as time goes by. I will say as far as build quality is concerned it's not bad, but IMO my old Onkyo, a 2009 model, had the look and feel of a more expensive receiver. But it's what's inside that matters most so hopefully this one last as long as my previous Onkyo.
