For offshore powerboat racing, high-visibility equipment can be particularly valuable where drivers and safety personnel operate in challenging conditions. Beyond its offshore racing applications, the striking orange finish makes the ST5.1 GT Offshore an excellent choice for drivers seeking a distinctive motorsport appearance. The helmet retains the proven ST5 GT shell geometry, enlarged eyeport, and integrated modular accessory provisions. Advanced Multi-Sandwich Fiberglass Composite Construction The ST5.1 GT Offshore uses Stilo's advanced multi-sandwich fiberglass composite construction, engineered to provide a balance of strength, impact energy management, and reduced weight. The composite shell provides a more economical alternative to Stilo's premium carbon fiber helmets while maintaining the ST5 platform's professional motorsport features. The helmet uses two shell sizes to provide a more optimized fit across its size range. Rather than relying on excessive interior padding inside a single oversized shell, Stilo uses different shell dimensions to help improve comfort and minimize unnecessary bulk. Approximate helmet weights vary by shell size and installed accessories. Integrated Communication System and Modular Side Ports One of the most important advantages of the Stilo ST5.1 GT Offshore Composite is its modular accessory platform. The helmet features integrated side ports that accommodate compatible motorsport communication electronics, hydration accessories, and forced-air cooling equipment. The Discovery Parts configuration is specified with communications pre-installed in the left-side port. This arrangement allows a compatible communication system to be integrated into the helmet without requiring loose external wiring or unnecessary modifications to the shell. Depending on the selected equipment, the ST5 GT platform can accommodate: Compatible Stilo racing communication equipment Integrated microphone and earpiece configurations Driver and co-driver communication systems Optional hydration tubes and drinking valves Optional top or side forced-air cooling systems Compatible aerodynamic accessories Communication compatibility: Confirm the installed communication connector and amplifier compatibility before connecting the helmet to an existing racing intercom system. Additional electronics and accessories may be required. Large Eyeport and Clear Anti-Fog Shield The Stilo ST5.1 GT Offshore Composite incorporates the larger eyeport design introduced with the ST5 helmet platform. Compared with previous ST4 models, the taller eyeport provides an expanded field of view and improved visibility of the surrounding racing environment. The helmet includes a clear 3mm shield with an anti-fog treatment designed to help maintain visibility during changing temperatures and humid conditions. A center-mounted shield locking mechanism provides convenient visor operation while wearing racing gloves. The helmet is compatible with selected Stilo ST5 replacement shields, allowing drivers to choose alternative shield finishes and tint options. Noise-Attenuating Ear Cushions for Driver Comfort Offshore powerboat racing and enclosed competition vehicles can produce considerable engine, wind, and mechanical noise. The ST5.1 GT Offshore Composite includes noise-attenuating earmuff cushions designed to help isolate the ears from surrounding noise. These cushions support driver comfort while providing a suitable foundation for compatible racing communication equipment. Removable ear cushions also allow drivers to customize their helmet configuration using compatible Stilo replacement components. Removable Interior Padding and Customizable Fit Proper helmet fit is essential for driver comfort and safety. The ST5.1 GT Offshore Composite features removable cheek and crown padding, with compatible replacement components available in different thicknesses. These options allow drivers to refine their helmet fit without changing the basic shell construction. Stilo also offers different earmuff cushion options for additional comfort and noise management. Stilo Fit Tip: Drivers who normally wear a 59cm helmet in another brand may prefer a 60cm Stilo configuration. Helmet fit varies by head shape, so measurements and a proper fitting are recommended. HANS and Frontal Head Restraint Compatibility The Stilo ST5.1 GT Offshore Composite includes factory-installed M6 threaded inserts for compatible frontal head restraint anchor hardware. These inserts allow installation of approved HANS/FHR post anchors for use with compatible head and neck restraint systems.

AP Racing J Hook Competition Disc Replacement Ring 372x34mm Details: Manufacturer: AP Racing Manufacturer US part number right: AP-13.05.10052 AP Racing part number right: CP7177-350GC Manufacturer US part number left: AP-13.05.10053 AP Racing part number left: CP7177-351GC Slotted face: Yes Diameter: 372mm (11.65") Thickness: 34mm (1.34") Hardware included: No Torque specs for this disc and hardware assembly: 124 lb-in Iron Disc Benefits So what can AP Racing J Hook iron discs do for a car previously equipped with carbon ceramic discs? 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.
