Discovery Parts is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products same or next business day to ensure we meet your delivery deadline. FITMENT: Honda FK2 / FK8 Type R The Girodisc system is an upgrade to a two-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake discs. The two-piece floating rotors will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Girodisc rotors are lighter than OEM pieces. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC racing brake pads and Discovery Parts RF1 racing brake fluid, you have an unbeatable solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron, constructed in the USA and made to the same specification with the same material used by professional racing organizations. The rotors' curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by Girodisc in the USA and are cadmium plated for corrosion resistance. The alloy drive pins transfer braking loads while maintaining axial and radial float between the disc rotor and hat to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The pins are secured by Grade12 cap screws with hardened washers and mounted with anti-noise spring washers . The two-piece Girodisc design allows for rotor-ring only replacement to minimize future replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

Forgeline GA3 The Forgeline GA3 is the Performance Series street version of the popular, race-proven GA3R. (The GA3R is maybe a little too hardcore for the street; the GA3 derivative is the perfect compromise.) The GA3 adds material to the center of its racing counterpart, allowing use of our standard center cap. And it uses stainless steel (rather than titanium) ARP assembly hardware. Forgeline's I-beamed spoke technology reduces weight and applies additional strength and rigidity within the spokes of the wheel. The hidden ARP assembly hardware delivers a smooth clean look and makes wheel cleaning faster and easier. The design of the GA3 center allows plenty of room for caliper clearance and extreme brake fitment. And they have employed a new proprietary fast-drying super-strength sealer that is highly resistant to leaks and allows for quick and easy repairs. The GA3 is produced using Forgeline's traditional forging method, utilizing 6061-T6 aluminum with heat-treated rim-shells. And just like any Forgeline wheel, the GA3 is fully customizable in fitment and finish, including center-lock applications. NOW AVAILABLE with a stepped lip in 17-inch, 18-inch, 19-inch, and 20-inch sizes. This wheel is also available in a reverse deep lip/flat lip in 18-inch and 19-inch sizes. Derived From the GA3R Racing Wheel Three-Piece Performance Wheel Stepped-Lip Design (Also available with a reverse deep lip/flat lip in 18-inch & 19-inch diameters.) I-Beamed Spoke Technology Hidden ARP Fasteners Generous Brake Clearance Forged 6061-T6 Aluminum Heat-Treated Rim Shells Includes Standard Aluminum Center Cap Customizable Fitment and Finish Options Legendary Forgeline Quality and Customer Service

Girodisc "Magic Pads" are the solution to your squeaky, dusty, expensive factory replacement pads. They have lower dust than typical factory pads and much less than other performance pads. You won't be cleaning your wheels nearly as often! Additionally, they have great initial bite, something most less-expensive pads lack. But the real reason people like Magic Pads so much is they are the "silver bullet" to brake noise problems. Magic Pads are a semi-metallic composition that is easy on rotors and on your wallet. We recommend always replacing pads as a whole car set when switching compounds. All Magic Pads come with anti-noise shields pre-installed and included in the price. When comparison shopping, be sure to note the high quality of Girodisc components. If you have any questions, give us a call at 888-748-7223. We're happy to help!
