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 older and small dogs
Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
Healthy snack for the pups! I have an Oder dog and small dog both are able to enjoy these treats! They are hard enough to get some chews but soft enough to chew completely before swelling!

Pup Approved!
Style: Large - Red, Style: Large - Red
This winter my boy kept eating the ice outside which I didn’t like because I was not sure what chemicals could possibly be in the ice from the water seeping into my yard from the street. I decided to search Amazon for molds to make my own treats for my pup but then came across the GoSports Pets PupsCream Frozen Dog Treat Holder. Both my pup and I absolutely love it! My pup is approximately 30lbs and this bone treat holder is the perfect size for him. It’s heavy enough where it doesn’t move while my pup licks it as you can see from the pictures I provided. The bone treat holder did start on the floor but my pup took it upon himself to move it to his side of the couch, so the bone isn’t too heavy for your pup not to be able to carry it. I allowed my pup to keep his treat on the couch because as you can also see from the photos, it is not messy! I am completely shocked and surprised by the cleanliness of when a pup is eating the frozen treat unless this differs between each pup. Overall, the quality of the bone treat holder is very well made even when your pup puts it in his mouth to move its location. The bone treat holder usually keeps my pups attention for roughly thirty or more minutes. Once my pup is done with his treat, the cleanup is very easy as well and the bone treat holder air dries quickly or can be dried with a towel. I highly recommend the GoSports Pets PupsCream Frozen Dog Treat Holder to anyone that is looking for the perfect frozen treat holder toy for your furry best friend!

Great mental stimulation for dogs
Style: Large - Red
These ae great for my two large dogs! It holds just enough to be a nice treat instead of a full meal like some of the large freeze balls. I fill with a mixture of pumpkin, canned dog food, and a little kibble and freeze it. It keeps my big boys ( a Black Mouth Cur and a German Shepherd) busy for about 30 minutes and wears them out! They both take a lazy nap after licking for that long. The PupsCream bones do not slide across the floors and so far we havent ahd any mess from the dogs licking these. They are heavy and sturdy but you do need to supervise your pups if you have a big chewer as they are not indestructible. If you have a heavy chewer they will be able to chew pieces of this off given time. But, your dog shouldn't be using these, or any other rubber toy, unsupervised so that shouldn't be a problem. These don't replace physical exercise but are fantastic for rainy days when we can't let the dogs run and play in the yard as they are great mental stimulation. Experts say 30 minutes of licking is equal to a walk in terms of engaging their brains and calming them and from our experience this is true - our boys are tired after they empty these!

Dogs Delight!
Style: Small - Red, Style: Small - Red
I love this product! It is durable, strong and sturdy. It doesn't roll around, so the dogs can lick the contents without it going all over the floor. Same in the freezer - it sits on a shelf with no mess! The dogs enjoy their frozen fruit treats in it in summer and their softened, warm kibble with dollops of yoghurt or peanut butter, in winter. I have 4 so that 2 are in rotation everyday! I always have a new one in the cupboard in case I think of something extra to make. These make great gifts for other dog-mums/dad!
