Forgeline JO3C
$1,795.00
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. But since each wheel is custom built-to-order, Forgeline also offers special features like custom offsets and a large choice of finish combinations.

A1-128 Girodisc 2pc Front Brake Rotors (458 Challenge)
$1,750.00
FITS: Ferrari 458 CHALLENGE
Thunderhill is an Authorized dealer for GiroDisc products and we are 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.
The GiroDisc system is an upgrade to a 2-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake disc. The 2-piece floating disc 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 Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.
When used with Pagid or PFC performance brake pads, and Thunderhill RF-1 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 8-10 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 grade12 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 2-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.

A2-146 Girodisc 2pc REAR Brake Rotors
from $1,700.00
FITS PORSCHE 911 GT3& GT3RS / GT2RS (2014+) REAR WITH STEEL BRAKES
The Girodisc system is a direct replacement for the OE disc on the 991 GT3, GT3RS, and GT2RS with OEM iron rotors. No modifications are necessary, allows use of factory unmodified pads unlike most aftermarket solutions for this application. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.
The central hat section of the Girodisc rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from their 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 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 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 but eliminate the rattle and noise 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 when needed.
When used with Pagid or PFC racing brake pads and hi-temp RF1 racing brake fluid, you have what amounts to a truly amazing solution to overheating or warping rotors.
If your car came with OEM center lock wheels please select the center lock drive pin option.

Porsche 997 Turbo
This Girodisc system upgrades the OEM front brakes to a 380mm two-piece steel disc and aluminum hat. This two-piece "floating rotor" design will bolt directly to your GT4 front and work flawlessly with the OEM calipers. Particularly when paired with the Girodisc A2-155 rear rotors, upgrading your brakes to lightweight, high-performance Girodisc rotors maintains 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 RF1 racing brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped 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.

A1-266 Girodisc 2pc Front Brake Rotors GT4 ClubSport
$1,700.00
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.
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 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.
