SpeedCom Communications
Speedcom Single Ear Headset
$79.95
SPEEDCOM SCC-SEIH single ear intercom headset connects to all SPEEDCOM intercom units and features a built-in IMSA (4C) male connector for simple, reliable driver to passenger communications.
Earpiece speaker details:
The actual speaker portion of the SPEEDCOM SEIH Single Ear Intercom Headset is quite small. Measuring approximately 3.5 cm diameter, the thickness is 2 cm microphone and pillow pad. The pillow pad compresses easily and has the right amount of "give" for comfort.
Earpiece flex boom microphone:
Attached to the speaker is a flex boom noise cancelling microphone. The flex portion of the boom is 14 cm long and the mini microphone adds 4 cm, making it 18 cm long total for full reach around anyone's face to their mouth. The compact size works in every helmet we tried on.
Earpiece wiring harness:
Why do students pull the earpiece out by the wires? That is the question for the ages. SPEEDCOM changes how headsets are built by making the harness with a built-in molded plug. Other brands use the compression of the two speaker piece halves to hold the wire, but SPEEDCOM uses a wire that has the security block built into the harness during the manufacturing stage. Is this a more expensive way to build a headset? Certainly. Is it the better way to build a headset? Defiantly. Using the most popular form of racing protocols, IMSA, the lead is 3 ft and 19.5" long and a perfect length for either a dash mounted unit or shoved between the seat of a D.E. car, or in the instructors hand.

Power Source:
Actually the SpeedCom SCC-2MPI has two independent power sources. For the instructor going from car to car, the 4 internal AA batteries provides multiple weekends of power. For a driver who mounts the SCC-2MPI in their car a 12V DC flying lead (open wires) can power the intercom anytime vehicle power is available.
Mounting:
A incredible simple and secure roll bar "V" notch is built into this communicator. Just add 2 worm drive clamps, and you are secured beyond anything we hope you do to your car, even Rally racers.
Helmet Connections:
Built in are dual IMSA protocol (4C) female connectors on a lead. These dual IMSA cables are built in and ready to connect to your Roux integrated electronics or any other helmet with an IMSA helmet kit. If your helmet is not wired, simply add 2 SpeedCom SCC-SEIH Single Ear Intercom Headsets. This device requires headsets sold separately here.
Volume Control:
Dual independent volume controls are mounted on the front for easy control. The driver knob on the left has the main power control built in elemenating the need for a secondary master power switch. Clean, simple, powerful sound control.
Size:
The SCC-2MPI is compact and rugged. The main unit is 9 cm wide and the roll bar mount ears are 2.5 cm longer on each side.
Cable Lengths:
If you have ever had to purchase a race car electronics extension cable, you know how frustrating that is. Why did an engineer who makes a product think a 3" lead is what a racer wants. 12V DC Power Lead: 4 ft 3 in
Helmet Connections: 7 ft 2 in

STI-YA0851 ST5 Clear Anti-Scratch No Anti-Fog - Dirt / Offroad Friendly
High quality, Anti-fog visors shaped for the Stilo ST5 GT helmets. The Stilo ST5 series is unique in that the shield lock is located in the center position of the shield. The shield lock is released by squeezing the outboard sides together and that will then release it from the mount stud that is located in the center of the helmet. The reason for this is to "clean-up" the sides of the helmet where a side impact in a head containment seat may grab parts of the helmet. All Stilo ST5 shilds have the center release mechanism installed on it.All Stilo ST5 shields are treated with an anti-fog treatment and they do require special care. The best result we have by far is the Stilo Visor cleaner. Liberally spray the outside of the visor with the cleaner, and wipe in a single swipe with a micro fiber towel until clean and dry. If fingerprints or dirt remain, repeat as needed. A back and forth wiping motion will tend to leave lint from the rag on the visor, so the single pass works best. Repeat if necessary, but usually one pass works great.Stilo Visor Care: Do not use Windex or any glass cleaner containing ammonia, as this can harm the anti-scratch coating on the outside of the visor, and the anti-fog coating on the inside of the visor. This is the official Stilo Visor Cleaner.

Stilo ST5.1 GT Composite Helmet SA2020
from $1,008.95
$1,122.00
Stilo ST5.1 GT Composite Helmet SA2020
The ST5.1 GT Composite is Stilo's Snell SA2020 version of their best-selling kevlar-carbon composite helmets. With an autoclave molded shell, the ST5.1 GT Composite offers far superior safety compared to fiberglass and most composites from their competitors. You get all this without sacrificing comfort or features, as Stilo continues to focus on minimizing weight and maximizing flexibility.
With its large eyeport the Stilo ST5.1 GT Composite offers unsurpassed peripheral vision and all of the available tinted, mirrored, and iridium-colored visors (sold separately) have a center pinch-clip to make opening and closing easy, even while wearing nomex racing gloves.
Although updated to meet the newest Snell SA2020 certification, the Stilo ST5.1 GT retains its FIA 8858-2015 homologation as well. This makes the helmet legal for nearly all road race usage (some sanctioning bodies require FIA 8860 homologated helmets.
INTEGRATED FLEXIBILITY
The Stilo ST5.1 GT Composite is unsurpased in built-in flexibility. Its two side ports can be fitted with 3 different types of integrated communication electronics, forced air, helmet eject system, or a hydration system. Thanks to its innovative shell design, mounting and routing these options to the ST5.1 GT is sleek and seamless. When not in use, you don't even know the features are there.
Whether you're using side-mounted communications, side air, or a built-in hydration kit for staying hydrated during long enduro stints, everything is neat, tidy and completely out of the way when not needed. Stilo offers simply the best modular racing helmet on the market.
Industry-standard M6 threaded receivers are molded into the helmet shell to accommodate anchors for whichever head-and-neck restraint you use.
Size Note: We have found that customers who typically wear a size 59 helmet are most comfortable in size 60, which uses the large shell. Please order accordingly.
FEATURES:
Includes noise attenuating earmuffs to reduce exterior noise and maximize effectiveness of communications with your crew.

An effective helmet is one that fits properly. Have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head, starting at a point about an inch above the eyebrows and around a point in the back of the head that results in the largest measurement, finally wrapping back around to the front. It's a good idea to take a few measurements and order your helmet based on the largest.
