Thunderhill is an authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. We ship most Girodisc systems the same or next business day to ensure we meet your delivery deadline.
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 perfectly. The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from our 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 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA 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 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. Sold/priced in pairs
Forgeline
Forgeline GA3
$1,800.00
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’s 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.

The Stilo Venti WRC Carbon Fiber comes standard with factory-fitted HANS post anchors.
The most effective helmet is one that fits properly. To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.
This helmet will ship with signature required for delivery.

Brembo
Brembo Brakes Front 330x28 One Piece Rotors + Four Piston Calipers
$1,795.00
Brembo 330x28 One-Piece Iron Rotors and Four-Piston Calipers
For Drivers Who Demand the Utmost From Their Car
Designed and tested specifically for track-day enthusiasts and drivers who demand the utmost performance from their cars, these kits offer superlative performance for both everyday driving and demanding track-day sessions. Brembo kits consist of cross-drilled or slotted, ventilated one-piece discs and aluminium calipers with four pistons; a complete set of high performance pads; metal-braided hoses; and high quality hardware.
Solutions and Technologies Born on the Race Track
Braking systems consisting of motorsports-derived components offering levels of technology and performance without par on the market today and embodying the purest expression of Brembo's state-of-the-art technology.
The kit consists of aluminium calipers with opposed pistons which, depending on the car model and in increasing order of performance, may be composite, monoblock or even billet monoblock components, combined with cross-drilled or slotted one-piece oversized discs.
Brembo kits combine the best solutions available to offer the perfect solution for the individual characteristics of each model. The heart of the kit consists of aluminium calipers. These are also available as monoblock parts machined from a single billet of cast aluminium, which ensure outstanding rigidity and minimised deformation. The discs supplied in the kit are one-piece, featuring an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock by over 40%.
Cross-drilled and slotted finishes are designed and executed with meticulous precision. These holes or slots in the braking surface help dissipate heat and eliminate brake dust and gases. A set of high-performance brake pads with specific friction materials for each application, TÜV/DOT homologated metal-braided hoses, an adapter and high-quality fastener hardware complete the kit.
More Braking Torque and Thermal Capacity on Track
Using radial-mounted fixed calipers together with oversized discs gives the system greater braking torque and superior thermal capacity. The result is a braking action that is noticeably more immediate and decisive even in normal road usage, and is extraordinarily powerful and consistent under the repeated loads of track use.
Fixed calipers improve the durability and efficiency of the system: the opposed multiple pistons act on the pads with more precision, due to the smaller piston diameter and the reduced pressure exerted on each individual piston, while the greater overall surface area between the pads and pistons results in more uniform friction surface wear. The superlative stiffness of the calipers and the metal braided hoses reduce brake fluid absorption. The result is improved, more stable brake pedal pressure, making it possible to modulate braking force more precisely and enhancing pedal feel.
The greater dimensions of the braking rotor surface improves the dispersion of the heat generated by the repeated, intense thermal stress that the discs are subjected to, for consistent braking performance and pedal feel even after numerous laps on the track.
Eye-Catching and Unique Looks
With a combination of painted calipers (available in red, black or silver) flaunting the Brembo logo, and slotted or cross-drilled discs, the Gran Turismo kit gives an unmistakably sporty, eye-catching look to the car, offering that extra special touch for drivers who want their vehicle to stand out from the crowd.
Catering to the more discerning driver is the GT-R line of kits. These offer even more performance and consist of billet-monoblock calipers, slotted discs in diameters up to 405 mm and special high performance pads.

The concave design of the GA1R not only looks great but allows plenty of room for caliper clearance and extreme brake fitment, while the one-piece monoblock forging and I-beamed spoke design yield a wheel that is extremely stiff with fatigue strength equal to the proven GA3R.
Despite its strength, for most applications the GA1R delivers a high-performance weight reduction. This makes it perfect for motorsports and racing applications, or for the discerning street enthusiast who demands the ultimate in performance and quality.The GA1R is designed for racing, engineered with a 2,100-lb. street tire load rating to ensure strength and integrity even when subjected to the massive loads encountered using the stickiest racing tires.The GA1R is currently available in 18, 19, 20, and 21-inch sizes with a range of widths (6" to 15") and offsets. Like any Forgeline wheel, the GA1R is available in any of hundreds of fully customizable finish options.

Similar to Forgeline's race-proven GA1R Open Lug wheel, the GA1R Open Lug Cap Edition has significant material machined from the center area for additional weight reduction, improved access to the lugs, and an exaggerated extra-aggressive concave look. But unlike the Competition Series GA1R Open Lug racing wheel (which will NOT accept a center cap), this "Cap Edition" has a redesigned hub center and includes a unique specially-engineered tall center cap (with “Motorsport” engraving) to cover the hub spindle and protect it from the elements.
Perhaps the most advanced wheel that we have ever made, the fully-forged one-piece monoblock GA1R delivers a trifecta of greatness - strength, stiffness, and lightweight performance - thanks to 6061-T6 monoblock forgings, I-beamed spokes, and Forgeline engineering. Now for serious drivers who are looking for the ultimate in lightweight performance, the deal just got even sweeter with the new GA1R Open Lug Cap Edition. The GA1R is currently available in 18, 19, 20, and 21-inch sizes with a range of widths (6" to 15") and offsets. Like any Forgeline wheel, the GA1R is available in any of thousands of fully customizable finish options.

The Forgeline CF1 is a fully-forged one-piece monoblock wheel. Utilizing manufacturing technology similar to our very successful GA1R wheel, the concave 5-spoke design of the CF1 looks great and allows plenty of room for caliper clearance and extreme brake fitment. The one-piece monoblock forging and computer-simulated FEA design process yield a wheel that is ruggedly handsome, extremely stiff, and has excellent fatigue strength.
The CF1 is machined from a single forging of 6061-T6 aluminum. It is currently available in 18, 19, 20, and 21-inch diameters with a range of widths and offsets. (Please Note: Depending on size, the CF1 may be available in deep, medium, or shallow concave profiles. See sizing chart for details.) And just like any Forgeline wheel, the CF1 is available with fully customizable finish options.
The CF1 is also available for limited applications in Deep Cap (DC) and Extra Deep Cap (EDC) profiles. These Deep Cap profiles employ unique in-house lathe turnings that allow us to position the center cap deep within the center of the wheel and create an exaggerated extra-aggressive concave look. This option is an excellent choice for select vehicles including the BMW M3, Nissan GT-R, ZL1 Camaro, C6 Z06 Corvette (rear only), and certain Porsche models (rear only).
