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.

Better than the basic power strip
Color: White, Size: 2.5', Style: 2.5 ft
I needed to get a basic five or six outlet power strip and instead ended up with this . Since the power strip that I was going to get was for basic protection, and would be plugged into a surge suppressor anyway, I really wasn't concerned about how much protection it offered. Just having the extra outlets for additional small-to-medium electrical devices was important. While looking and comparing this with basic power strips, I decided to check the manufacturer's site to see what specs they offered, since the ones here seemed to be a bit inadequate. Here's what I found: * 555 Joule energy rating provides maximum protection of all your sensitive electronic devices * 6 Surge-protected outlets supply 2-line AC protection * 2.5-foot power cord delivers optimal, safe AC power through a 14-gauge heavy-duty cord * Filters EMI/RFI noise up to 43 dB reduction * Maximum Spike Amperage of 36,000 Amps * Lifetime Product Warranty * $15,000 Connected Equipment Warranty The pros on this unit include the price, the basic surge protection, a short but sturdy power cord, and good basic construction. It has a power/reset switch that's recessed at the top of the unit near the power cord to prevent accidental shutting down. On the negative side, like so many of these units, the outlets are too close together to put more than a couple transformer-type devices like cell phone chargers and such. Just a couple of comments on the specifications listed above to those who may be interested: if you're going to plug high-end expensive electronics into one of these, don't do it. This is an adequate but very basic unit, and you want to consider getting a better grade surge suppressor for large screen televisions, good computer systems and such. No surge protector is 100% effective, but sure that the product is listed as a transient voltage surge suppressor, and that it meets the criteria for UL 1449, the absolute minimum performance standard for surge suppressors. I'm no electrical engineer or electronics technician, but if you're going to protect an expensive jogging machine, your new 52-inch television or Apple iMac 27-inch desktop system, you need better than an under $10 surge suppressor or power strip. A friend who I will refer to as the 'cranky electronic tech' told me to look it up on the 'Net, but make sure that whatever I got for protection of "really good stuff" needed to be minimally have a UL1449 3rd Edition certification and be rated at 1400 joules of surge protection or higher, and the rest would fall into place. The that I've used for years with my large electronics is rated at 3330 Joules, and meets those specs. If you plan to use a basic surge suppressor to charge cell phones and the like with their transformer plugs, units with right-angle outlets are a better, though more costly choice. My personal choice for mid-range protection combined with outstanding quality is the , a 5-star product that I own and have reviewed here. I run two notebook computers with this, along with a few chargers. There are others if you look. If all that you're looking for is a basic surge protector with a reasonable amount of surge suppression, then this one from Belkin is a decent choice, and certainly better than the basic power strip. I actually came back recently and bought a second one this year. But if your needs call for more, then the above listed alternates may be worth a look. 4/25/2012

It just works, and that is all that matters
Color: White, Size: 10 ft (Pack of 1), Style: 10 ft
It's a Belkin product. Do you really need to know anything more? My roommate bought a really crappy multi-outlet, it worked for the low wattage stuff, but for the higher wattage stuff the internal breaker kept popping. I bought this one, and it hasn't failed me yet.

price, features, 5 star
Color: White, Size: 4 ft (Pack of 1), Style: 4 ft
i cant comment on its performance as a surge protector but as a power strip its awesome. its redic cheap plenty of plug ins super thin, my other strip is twice as thick the on off switch is hidden which is great to not accidentally hit it, and with having kids around the cord length is perfect for my needs. its plug in behind a chair and a half and comes around the side and has plenty of play to move and plug and unplug the only con i can say about it which is not really a con because it wasnt designed for it. your only going to fit 1 big adapter on the end, or your going to have to give up plug ins to have more than that. but that clearly isnt the design of this strip. its about being thin, compact, hidden, and cheap. you want one that can do everything, your going to have to spend more

Everything You Expect, Nothing You Don't
Color: White, Size: 2.5', Style: 2.5 ft
The power strip got here quickly and works as advertised. I needed another strip because I had an extension cord setup for game systems that was NOT toddler-safe. Now I've got the plugs all tucked away at the back of the cabinet and away from little hands with no protruding prongs. Also, power strips are a good way to save on your electric bill. Things like game systems that really don't need power when you're not using them will draw what's sometimes called "vampire load." It can really add up on your electric bill if you have a lot of things plugged in that aren't in constant use. If you run them through a strip and switch the strip off when you're not using them, you can save a few bucks on electricity. If you're a dad like me, a lower electric bill makes you wanna hang it up on the fridge and tell everyone what a good job you did and how proud they should be of you. There are WAY more fun things to do with a few spare dollars than spend them on running power to appliances you're not even using.
