This Girodisc system is a 380mm two-piece steel rotor and aluminum hat combination, a direct-replacement upgrade for the one-piece OEM GT4 Clubsport steel brakes. The A2-266 will bolt directly to the GT4 ClubSport and work perfectly with your OEM calipers. There are two main reasons for replacing your OEM rotors: first, the Girodisc rotors are designed to shed heat more effectively than the original rotors; second, the slotted Girodisc A2-266 will far outlast the OEM drilled rotors. When subjected to intense heat in a racing or track-day environment, the drilled holes in the OEM rotors originate cracks which can lead to rotor failure. When paired with the Girodisc A1-266 front rotors, your factory brake bias and ABS efficiency are maintained. When used with Pagid or PFC performance brake pads, and Thunderhill RF1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing 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 which is constructed in the USA and is 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 eight to ten high strength alloy steel drive pins manufactured by Girodisc in the USA to our own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by Grade 12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The two-piece Girodisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/priced per pair.

Girodisc A2-272 Two Piece Floating Racing Brake Rotors These Rotors Fit The Following Cars (w/ OEM Steel Rotors) Porsche 992 GT3 Rear Porsche 992 GT3RS Rear Porsche 718 GT4RS Rear The Girodisc system is a direct replacement for the OEM rear discs on the 992 GT3 & GT3RS and the 718 GT4RS with OEM iron rotors. No modifications are necessary, allowing use of unmodified factory pad shapes unlike most aftermarket solutions for this Porsche. The disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with lightweight, high performance replacements -- as opposed to a big brake kit -- your factory brake bias and ABS efficiency are preserved. The central hat section of our rotor is made from strictly USA-sourced 6061-T6 aircraft specification aluminum. The rotor is made from Girodisc's own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc. The rotor utilizes 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 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to their own specifications and cadmium plated for long-lasting corrosion resistance. These pins take the load from braking while maintaining the axial and radial float between the hat and disc. The pins are secured by Class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion, eliminating the rattle and noise commonly associated with floating rotors. This float also allows the rotor to self center between the pads. Once the Girodisc system is in place, simply replace the cast iron rotor ring when needed. When used with Pagid or PFC racing brake pads and hi-temp Thunderhill Performance RF1 racing brake fluid, you have what amounts to a truly amazing solution to overheating or warping rotors. If your car came stock with OEM center lock wheels please select the center lock drive pin option. Sold/priced in pairs.

CMS Performance Roll Bar for Shelby GT350, GT350R, GT500 This Roll Bar Fits The Following Cars: Ford Shelby GT350 (2016-2020) Ford Shelby GT350R (2017-2020) Ford Shelby GT500 (2015+) The Best Roll Bar On Earth for Ford's Track Day Monsters The CMS Performance Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market for the Shelby GT350, GT350R, and GT500. In designing our Shelby roll bar, safety, strength, and structural integrity were our primary goals. That's why it is fully TIG welded from ultra-strong Docol R8 Advanced High-Strength Steel sized 1.75" diam x .095" wall, vs. the mild-steel tubing other companies use. Docol R8 is 30-35% stronger than DOM mild steel and even 10-15% stronger than 4130 CrMo steel. This allows CMS Performance to design a roll bar that is stronger and lighter weight. Precision CNC machined interlocking roll bar clamps, made to our specifications in the USA, make joining the main hoop and kickers easier during installation while giving the CMS Performance roll bar a premium, finished look. Adding an optional Shrader Rear Seat Delete Kit (not necessary on the GT350R) gives your roll bar installation a from-the-factory OEM look. American Made Safety for an American Icon Let's face it, safety is the primary reason to install a roll bar in your Shelby. So the CMS Performance Shelby Roll Bar is designed to place your harness shoulder straps at both the proper angle (0° to -20°) and distance to the driver. The rear kickers bolt to a strong existing bulkhead, requiring no reinforcement plates beneath the floor pan. Our use of state-of-the-art Docol ultra-high-strength-steel tubing throughout allows us to keep the driver's rear view unobstructed by diagonal braces, which also keeps weight down. Every detail is engineered with safety and structural integrity as our primary goal. Precision Crafted and Custom Finished in OEM Colors The other reason to install a roll bar is because it really complements the aggressive, race-inspired styling of the Shelby S550 and Shelby GT350/R/500. We're gear heads, we get that. So each bar is crafted by hand by master fabricators, 360o TIG welded for the ultimate in strength and durability, and then custom powder coated in our facility (at no extra charge). We've color-matched powder to most of Ford's factory paint colors for a truly customized look, or you can choose from thousands of custom colors and finishes like the amazing Superchrome, giving your Shelby a personalized look that will last. Going from raw Docol tube stock to a gleaming finish, every roll bar is handcrafted by our most experienced cage- and race car builders. Nothing is left to chance. The CMS roll bar is designed to give you an unobstructed view through your rear window. None of your plastic interior trim needs to be removed or cut, just a little carpet that is hidden away. So if you ever need to put your car back to stock, it will look as though the roll bar was never there. Easier Installation and Lots of Options for Your Shelby Roll Bar Check out the GREAT installation video here! 1 Complete, detailed instructions make installation pretty simple (figure about two hours if you're reasonably handy; having a buddy helps!) All the supplied installation hardware is American made: Grade 8 mounting hardware and an industrial carbide drill bit. So you don't have worry that you don't have what you need for a flawless installation. You can add six-point or four-point harnesses to your order to take full advantage of the safety upgrade your roll bar represents. The CMS Performance Sub Strap + Lap Belt Mount makes securely installing your racing harnesses easy. Check out the drop-downs above. Many customers also add CMS Locking Harness Collars to keep harness shoulder straps right where you want them (they're not required for safety, but a lot of people like the look.) 1 Thanks so much to our customer "@1_trickpony_" for putting in the time and effort to shoot and edit a fantastic installation video!

FORGELINE FU3C The Forgeline FU3C wheel pays homage to the classic Porsche wheel of the 1960s and 1970s. But unlike its predecessor, the FU3C is a modern 3-piece wheel that is manufactured from fully forged 6061-T6 aluminum centers using the latest engineering and manufacturing technology. The FU3C borrows from the classic wheel's five-spoke design with dimensional inverted tapered spokes, but rather than recreate yet another replica, the Forgeline engineering team spent many hours refining the FU3C design to create a wheel with a unique, distinctly Forgeline character. This resource-intensive process yielded a wheel with a concave center, carefully-tuned proportions, and extended spokes that reach out beyond the rim register and over the stepped lip outer. Like all Forgeline Concave Series wheels, the FU3C locates the pad inboard of the outer rim to deliver depth and scale within the wheel center for a more modern look. Available in both deep concave profiles (for the most striking appearance) and shallow concave profiles (to create a staggered look or accommodate narrow width or higher-offset applications). These 3-piece wheels are assembled with hidden American-made stainless-steel ARP fasteners and Heli-Coil inserts. The FU3C is designed with a stepped lip outer in 19-inch, 20-inch, and 21-inch fitments. Custom Made-to-Order for Each Customer and Each Unique Vehicle Application Unique Center Design is Precision-Machined from Forged 6061-T6 Aluminum Retro 5-Spoke Design Inspired by Classic Porsche Wheels Concave Profile – Both Deep and Shallow Concave Profiles Available Unique Full-Length Spokes Extend Beyond the Rim Register and Reach Over the Step of the Outer Rim Shell Available in 19", 20" and 21" Customizable Finish Options Legendary Forgeline Quality

Fitment: Chevrolet Corvette C8 Z06 DESCRIPTION These GiroDisc 2-piece rotors are a direct replacement for the front rotors on the Corvette C8 Z06 with the Z07 carbon ceramic brakes. Our 2-piece, fully floating assemblies are direct replacements for the carbon ceramic rotors and utilize the factory calipers, but with a different pad shape. This pad shape is commonly known as D1405, and is the same pad shape as a Z06 without the Z07 package. Please contact us if you need help finding pads. The rotor rings are machined from a proprietary casting made of high-carbon steel formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 72 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The 2-piece design means a reusable hat which can be attached to new rings (part number D1-320) when they need to be replaced. All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodize finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware. The minimum thickness at which we recommend replacing these rings is 34mm. We also recommend replacing them if a crack leads to the edge of the ring. Sold and priced per pair.
