Forgeline JO3C When country music sensation James Otto had a vision for the perfect wheel for the pro-touring restoration of his childhood Chevelle, he knew just where to turn. Forgeline's engineering team worked with James to create the JO3C, a throwback to the original rally wheel found on Chevelles and Camaro Z/28s of the 1960s and 1970s. But unlike the original, the JO3C is a modern 3-piece wheel manufactured from fully forged 6061-T6 aluminum centers using the latest engineering and manufacturing technology. A traditional five-spoke design with inverted tapered spokes and creative machining details, the JO3C evokes a traditional muscle car flavor while delivering modern technology and performance. The JO3C is built with true forged 6061-T6 aluminum centers, aircraft-quality ARP stainless steel hidden fasteners, and heat-treated rim sections. The JO3C is available with a flat-lip reverse outer in 18-inch, 19-inch, 20-inch, and 22-inch fitments and features a standard powder coated center finish with a polished outer rim.

Girodisc A2-155 Two Piece Floating Racing Brake Rotors These Rotors Fit The Following Cars (w/ OEM Steel Rotors): Porsche 981 Cayman GT4 Rear Porsche 718 Cayman GT4 Rear Porsche 991 Turbo/Turbo S Rear This Girodisc system upgrades your Porsche OEM rear brakes to 380mm two-piece steel discs and aluminum hats. This two-piece floating rotor design will bolt directly to your Porsche GT4 or Turbo and work flawlessly with the OEM calipers using the included machined aluminum spacers. Especially when paired with the Girodisc A1-066 front Porsche rotors , upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Much lighter than the OEM rotors, Girodisc rotors reduce rotational and unsprung mass giving you stronger braking and faster suspension response. Combined with Pagid or PFC racing brake pads and Thunderhill Performance RF1 racing brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked OEM Porsche rotors that result from high-performance driving. The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc. The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors.This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs. Sold/priced per pair.

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 A1-266 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 A1-266 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 A2-266 rear rotors, your factory brake bias and ABS efficiency are maintained.

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.

Sparco QRT-C Carbon Racing Seat The QRT-C is an all-carbon fiber version of the QRT-R. The QRT-C is the lightest “large” size carbon fiber seat on the market. The QRT-C weighs 12.5lbs (with padding and cover) and is constructed from “Pre-Preg” aerospace grade carbon fiber, also known as Dry Carbon. The QRT-C was specifically designed for a large driver and it fits up to a 36” waist driver comfortably. The QRT-C is unique because it was designed to fit a larger driver but has excellent fitment into smaller cockpits The QRT-C requires the special QRT Side Mounts (#600QRT) which allows the seat to be racked back for a comfortable seating position.
