This package is designed for the serious racer who demands very high performance, lightweight comfort, and advanced safety features. The Discovery Parts Performance Racing Backpack makes it easy to tote your helmet and other essential gear to and from the paddock! (Helmet not included.) SPARCO EAGLE LT FIRE SUIT The Eagle LT is a limited edition suit available only for the US market. The Eagle LT features an all-new design in two colorways. This is a limited edition suit, only available for 2021 (while supplies last). The Eagle LT is the result of over 3 years of research and development. Sparco has patented a new technology called HOCOTEX® which revolutionizes the way racing suits are made. This new exclusive Sparco technology creates a single layer fabric which has the protection of what is normally achieved by a multi-layer fabric. The Eagle LT is FIA approved. Thanks to HOCOTEX®, the Eagle LT is three times more breathable than a suit produced using traditional technology. The use of this relatively thinner fabric along with large side and back stretch panels and 360 degree arm gussets give the Eagle LT ultimate flexibility and comfort. The Eagle LT uses at new stretch material called Eagle fabric. This Eagle Fabric is lighter, more breathable and abrasion resistant than the traditional stretch material. Traditional racing suits have layers of fabric sewn together with a quilted pattern. The quilting provides air space between the layers which bloats in a fire, this provides thermal protection to the driver. HOCOTEX® creates a honeycomb structure with internal air cells that ensure the driver even more fire protection. Traditional box quilting creates an average of 300 air chambers in a size 52 suit. The Eagle LT has over 60,000 microcell air chambers which provide a 10 to 12% increase in heat protection performance. SPARCO SKID SHOES The Skid driving shoe is a lightweight, unique design that has genuine ultra-soft leather upper with an offset closure system without a traditional shoe tongue. This design feature moves the potential pressure point of traditional laces from the top of your foot to the side which gives unparalleled comfort. The Skid also features a stretch rear collar for flexibility. It has a comfortable cushioned inner sole and an all-new slim rubber sole that is anti-slip, anti-static, and oil and fuel resistant. All-new anti-static pure rubber outer sole features a special texture for better pedal grip. The Skid is SFI and FIA approved. SPARCO ARROW GLOVES The Sparco Arrow racing glove provides incredible grip and superior comfort. The palm is printed with high-grip HTX, a Sparco patented material that increases grip, comfort and dexterity. HTX is strategically placed for maximum steering feel and performance. Another Sparco-exclusive feature is Touch-S technology, a Touch Sensitive index finger and thumb. Sparco's patented fire resistant touch sensitive material allows you to use your touch screen data acquisition electronics or phone lap timer apps without taking off your gloves. The Arrow is ultra-lightweight with pre-curved fingers, external stitching and a unique inner thumb seam that gives unparalleled comfort on long stints. The Sparco Arrow is both FIA and SFI approved.

Increased airflow and slower heat transfer to other brake components- AP Racing J Hook discs have a unique, high-count vane design that promotes airflow, heat evacuation, and rapid cooling. They don't rely on a large surface area to cool via radiation. The iron discs will move more air than your carbon ceramic's, and as a result they won't heat your brake pads, caliper pistons, and brake fluid up as quickly. You'll be able to run longer sessions without brake fade, and you'll enjoy the confidence that comes along with them. They'll also make any brake ducts that you have on the car more effective and useful. Huge range of compatible brake pad compounds- Iron discs will open up a much greater range of available brake pads. You'll be able to achieve a different feel, and tailor your brake setup depending on your needs and environment, whether that is running an AutoX or the most demanding racetrack in your area. You'll also likely be paying less per brake pad set than you were previously, and your pads will last longer. Inexpensive spare discs- You'll no longer have to spend thousands of dollars when it's time to replace your discs. AP Racing J Hook's typically only cost $400-600 per iron disc ring, so you won't have to stress about anything happening to them. They're inexpensive enough that you can always keep a spare set on hand, so you won't have to worry about any brake-related downtime when you're out at the track. Durability- Iron discs can take a beating. You can stash your spares in your race trailer, and you won't have to worry about handling them, covering them, dinging them, or chipping them when changing your wheels. As you can see, although iron discs do come with a slight weight penalty, they're still the smart choice if you run your car hard on the racetrack. They're the obvious solution that has been proven countless times on tracks around the world, at all levels of motorsport. Among iron disc choices, there are none better than AP Racing J Hooks. AP Racing J Hook Discs are the epitome of endurance racing components. They will hold up extremely well to any abuse you plan to throw at them. These discs have been proven time and again in professional racing, winning many races and championships (SRO, IMSA, WEC, Rolex, etc.). Two-piece Floating Design with Aluminum Hat As is the case with most metal, iron brake discs grow substantially when heated. As it is heated, a disc expands radially, increasing in diameter and circumference. One-piece disc designs run into problems when this occurs. Look at the picture below and imagine the disc is being heated on the track. As the disc expands, the outer edges of the disc are pulling away from the center of the disc, but there are no built-in provisions to allow for that expansion. The edges of the disc therefore pull, lift, and distort, which is called coning. Now imagine that disc vertical on the car, running in your caliper. Coning directly impacts the brake pads’ contact with the disc, leading to uneven wear and tapering, and even a long brake pedal. Two-piece discs on the other hand, compensate for the expansion of the disc as it heats. This is accomplished by building ‘float’ into either the disc itself, or the disc hat/bell. In this case, the float is in the disc. If you look closely at the picture below, you can see that the mounting holes for the hat attachment bobbins are not round. They are an oblong shape. These channels allow the hat mounting hardware to slide as the disc is heated and expands, allowing the disc to run true in the caliper without distortion. That means less distortion, stress cracks, and pad taper.
