Welcome to GiroDisc!

Brake rotors have long been the overlooked link in performance car braking systems. Traditional 1-piece brake rotors are heavy and retain heat, diminishing their effectiveness and adding unsprung weight that adversely affects handling.

When GiroDisc was founded in 2003, we made it our mission to design and manufacture 2-piece brake rotors that would perform flawlessly at the limits. Our fully-floating design uses tension hardware to ensure that our rotors are silent on the street, but ready to go on the track.

By specializing in this area, we can dedicate our efforts to push our engineering and manufacturing to the highest levels in the industry. Customers around the world have found success maximizing the capabilities of their existing brake systems by installing GiroDisc rotors. This often negates the need for a pricier, more complex upgrade like a big brake kit.

GiroDisc is headquartered in Bellingham, Washington, where we design, engineer, manufacture and fulfill orders on site.


The primary purpose of the Girodisc system is to reduce unsprung and overall vehicle weight. The secondary purpose is to increase the ventilation and cooling capacity of the brake disc while retaining it's original dimensions. This is accomplished by using two-piece disc construction. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum.

The disc is made from cast iron, to the same specification and material as used by professional racing organizations. It is a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc. The rotor and hat have a floating mount system, which utilizes high strength alloy steel drive pins, manufactured by Girodisc to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by grade 12 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring clips on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor
to self center between the pads.


Important Questions Answered

Q: What is required to install the Girodisc system?

A: The Girodisc system is a direct replacement for the OE disc.
No modifications are necessary. The disc will bolt directly to the car and work with OE calipers and pads perfectly. Once the Girodisc system is in place, simply replace the cast iron rotor when needed. Some discs are larger in diameter and come with caliper spacers. If longer bolts are required, they are also supplied.

Q: How does reducing weight of the braking system benefit the vehicle?
A: The Girodisc will generally weigh between 4 8 lbs less than the oe disc it will replace. This is due to the heavy cast iron hat section being replaced with lightweight, high strength aluminum. The mass of any vehicle requires energy to accelerate or decelerate. Reducing the vehicle mass improves acceleration, and requires less energy to be dissipated during deceleration. Rotating mass requires additional energy in order to increase or decrease its speed of rotation. Decreasing the mass of the disc has a great benefit due to reduction in rotational inertia. This will allow more of the braking force to be available to decelerate the vehicle, not the disc.
Additionally, the mass of the brake system is also unsprung mass. Reducing the unsprung mass has the additional benefit of improved suspension performance, resulting in enhanced ride and handling. Rotating masses require additional energy to vary the plane on which they turn. The lighter the disc, the quicker the response of the vehicle steering due to the reduction in gyroscopic effect/rotational inertia of the disc. As an example, compare the weight of the Ferrari 360 OE disc at 18.2 lbs, and the Girodisc at 14 lbs. The Girodisc is 4.2 lbs lighter per disc. Replacing all four discs will save 16.8 lbs of rotating, unsprung mass.

Q: Why slotted discs?
A: The edges of the slots continuously clean and refresh the pad surface. This will allow the pads to have a maximized friction surface always available. Additionally, they prevent containments from collecting between the pad and disc interface.
The disc is lightened, decreasing its rotational inertia.
Slots prevent the formation of a water film on the disc in wet weather, maintaining the best brake response.

Great For Battery Chargers On a Shelf!
Love this power strip, had it for probably a year plus now abs works great! The sole reason I purchased this item was so I can select what stays on and what gets turned off. I have this in my utility room and the sole purpose is to plug in battery chargers and to be able to turn off those battery chargers and leave the charger sitting there with the battery in the charger with no power. There is a light that tells you when a product is on and when a product is off . Example: I have AA&AAA battery charger, Ryobi leaf blower charger, Ryobi edger charger and any other charger I want. I have a night light plugged into it because angle allows that. The strip also has a USB that I use for a rechargeable Dremel used for dog nails or toy could use it for cell phone etc. My Flying Pig Grooming Dryer is attached and used with this strip as well. I have had no tripping issues with this power strip but I do keep in mind one high power items such as my grooming dryer at a time. I have a different company's power strip in my room just for you ladies it hidden behind a mirror and you can keep all your appliances plugged in and cell phones with the option of turning them all off with a button, cutting off power. This is an easy to reach power cord great for putting on a shelf. I am not sure how well it would work behind furniture due to the angle of the plugs. This worked with no issues and I would recommend this and purchase again. Now I am not concerned about saving items due to power surges with this power strip, I have strips that cost a lot of money a lifetime guarantee for those high end electronics like computers TV sets Etc

Good setup
This has been super useful and functional, I recommend it as it’s a nice way to keep your setup organized, I enjoy having the on and off switches go each outlet, only call out would be the buttons light up when on to show they are on and they are quite bright, so take note of it, it catches me off guard sometimes when I forget they light up and I turn my lights off, but it’s easier to keep in mind what I have charging. The speed of charging is good, the amount of plugs is a fair amount, I plug in my head phones, phone, watch, power bank and monitor. Then there’s the two usb as well as 2 usbc ports, it’s very convenient. It held up well it’s definitely good quality.

Thoroughly enjoy this product and will purchase again
I purchased two of these at different times. I really like this item. I like the idea that I could shut off some of the switches that I really don’t need. I have one set up in the guest room for when we have company they can turn on whatever plugs they need. I’ll always have alarm clocks lamps telephone jacks hooked up, but all the switches are turned off so it doesn’t waste electricity. (that’s my theory anyway.) I purchased a second one to go beside my chair in my living room I don’t need that many outlets at all times but occasionally I do and I enjoy again like having the opportunity to shut off any outlets that I’m not needing at the time it seems to me it’s a good power saver and I do like the USB ports everything fits and it’s perfectly organized and it’s great quality surge protector and durability. I hope this review assist you in anyway and I will probably come back and purchase a third one for another room once I get that room cleaned out Truth Hurts on it, but that was my testimony.. This is my honest review in my opinion I hope it’s able to help you make your decision. I personally don’t think you would go wrong but I don’t know what you’re plugging into the outlet so I think that makes a bit different. I just use it for lamps and telephone jacks or small items I don’t use anything. It pulls a lot of voltage. . Y’all take care of yourselves be kind to one another and go see your parents or your grandparents or a family member if anything else pick up the phone and tell them hello and you were thinking about Let’s spread love, not hate

Has a ton of quality of life features!
These are one of those products that makes you go "why doesn't anyone else do this"? First off, the 45 degree(ish) angle that the outlets are at. Since a lot of outlet adapter plugs can be plugged in upside down, the angle of the outlet helps considerably for semi-tight spaces. While also still having room to turn the individual outlets on and off. The width spacing is also considerably large so those beefy power bricks won't overlap/block-off other outlets. Secondly, the prior-mentioned outlet on and off switches. Each individual AC outlet has its own on/off switch. So if I have a lamp that always needs to be plugged in, I can leave that on. If I have a USB C adapter brick to charge my phone, I can turn that off when its not in use. Without needing to turn off the lamp's outlet in the process. Thirdly, the always on USB A (the rectangular USB outlets), and the USB C ports to the top side of the outlet. Please note that the USB C ports are about 20 watts. So while it can TECHNICALLY charge a laptop, its best used to passively charge a laptop when it isn't being used. Not while actively using a laptop. Since even moderately efficient laptops can draw watts well into the 40's range. That aside, when used within their intended watt ranges, they're extremely convenient to have in addition to everything else. I generally use them to charge things like power banks. Possibly low powered USB C devices like a Nintendo Switch or even a GPD microPC which draws 15 or so watts while in use. So while the ports aren't the highest in terms of watts, there's times of many where I didn't care how many watts a port had, I just needed a USB port period. Fourth wise, the safety protections. If you somehow manage to overload this outlet, it can cut off its own power. It can be "reset" by pressing the red button to the side. Fifthly, the actual plug to plug the power outlet into a wall or in my case a UPS machine, is insanely flat. With the cord being at a 45 or so degree angle. So even if its on a top outlet, it probably won't block off most plugs from using the bottom outlet. Sixth and finally (at least from what I remember off the top of my head 😂), the wire that connects the power outlet to your power source is really flat and easy to manage. All of these traits makes it one of the least contentious things anybody can buy. Its just a straight up quality of life improvement. If I ever need more power outlets, I know which one to double dip on!
