AiM Sports SmartyCam 3 Corsa Introducing the upgraded SmartyCam 3 Corsa, the newest iteration of the AiM SmartyCam HD. This enhanced version takes the well-known design to new heights, featuring an improved Global Shutter and the ability to capture video at up to 60 frames per second. Unlike conventional action cameras that cater to various extreme activities like skydiving or riding monstrous waves, the SmartyCam HD is meticulously crafted by dedicated motorsports enthusiasts who live and breathe the racetrack. Its narrow angle lens is specifically tailored for seamless mounting in sedans and sports cars, neatly fitting within the A-pillars for optimal placement. The new SmartyCam 3 Corsa camera has been designed for motorsport with a single purpose. Get The Best Motorsports Videos With Amazing Data Overlays The AiM SmartyCam 3 Corsa camera overlays all the data from both GPS and AiM loggers connected to your ECU. The Motorsports Camera With A Full Data Logger Built In All data received by the AiM SmartyCam 3 Corsa from both the CAN bus and its own internal sensors are recorded in mp4 files produced at the end of your stint or session. Your SD (or Micro SD) card contains all the information you need for a deep data analysis. (SD and Micro SD cards sold separately.) The video of a whole session, once downloaded on your PC, can now be split with a simple click into individual videos of each lap. So now you can simultaneously watch two side-by-side to see where you were faster or slower. The same operation can be performed with a SmartyCam 3 Sport video recorded on the same track. You'll be able to compare your best lap with other drivers, other set-ups, and so on! The Only HD Camera Built for the Punishment of Motorsports An on-board or in-car camera designed for motorsport must guarantee great resilience and reliability in the extreme working conditions typical of racing, and against the most adverse weather. That's why the AiM SmartyCam 3 Corsa is IP65 waterproof. Constructed from machinery-molded aluminum, PA fiberglass reinforced and featuring a sapphire frontal lens glass, the SmartyCam 3 Corsa is built like a tank. The Convenience and Ease of Auto Stop and Start You have other things to think about while you're at the race track, and the AiM SmartyCam 3 Corsa is designed with that in mind. That's why it switches on and off automatically, as well as starting and stopping recording in the same way. No Video Wave Effect with the Motorsports CMOS Global Shutter At speed on the race track, chassis vibration, engine rumble, and wind buffeting cause vibrations that are a big problem for generic sports video cameras. The AiM SmartyCam 3 Corsa is designed and built specifically to handle that environment, so you'll never experience that seasick “wave effect” you get in videos recorded by generic cameras. Ultra High-Quality Vide with Small File Sizes Generic HD cameras are absorbed with having the highest pixel count. The result is that their video files are huge, eating up memory and processing power. AiM SmartyCam 3 Corsa videos, on the other hand, have the same high video quality as other HD cameras, but their files are smaller because the H.264 compression system parameters have been optimized to perfectly balance video quality and file size. AiM SmartyCam 3 Corsa Details: Video format: H.264 compression; 1,920x1,080 pixels @ 60 fps Display resolution: 128x128 px Lens: low distortion, sapphire front glass CMOS sensor: global shutter Field-of-view: 67º or 84º Internal battery: rechargeable lithium External power: 9V to 15V Supported Micro-SD card: up to 2 TB (not included) Connectors: three Binder 712 female connectors; one USB-C Operating temperatures: -10°C to 50°C (14ºF to 122ºF) Auto power on: yes Auto power off: yes Auto start/stop: yes Camera body: coated aluminum Dimensions: 102.2 x 63 x 46.5 mm (4 x 2.5 x 1.8 in) Weight (w/ battery): 280 g (0.62 lb) Waterproof: IP65

CMS Performance Roll Bar for Mustang S197 2005 - 2014 This Roll Bar Fits the Following Cars: 2005 -2014 Ford Mustang coupe, all (S197) Click here for installation instructions The Best S197 Mustang Roll Bar on the Market The CMS Performance Mustang Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market. In designing our Mustang roll bar, safety, strength, and structural integrity were our primary goals. That's why it is fully TIG welded from ultra-strong Docol R8 Advanced High-Strength Steel sized 1.75" diam x .095" wall, vs. the mild-steel tubing others use. Docol R8 is 30-35% stronger than DOM mild steel and even 10-15% stronger than 4130 CrMo steel. This allowed us to design a roll bar that is both stronger and lighter. Precision CNC machined interlocking roll bar clamps, made to our specifications in the USA, make joining the main hoop and kickers easier during installation while giving the CMS Performance roll bar a premium, finished look. CMS Peformance Roll Bar is the Standard for Safety Let's face it, safety is the primary reason to install a roll bar in the first place. So the CMS Performance Mustang Roll Bar is designed to place your harness shoulder straps at both the proper angle (0° to -20°) and distance to the driver. The rear kickers bolt to a strong existing bulkhead, requiring no reinforcement plates beneath the floor pan. Our use of state-of-the-art Docol ultra-high-strength-steel tubing throughout allows us to keep the driver's rear view unobstructed by diagonal braces, which also keeps weight down. Every detail is engineered with safety and structural integrity as our primary goal. American-Made Cool for an Iconic American Car The other reason to install a roll bar is because it really complements the aggressive, race-inspired styling of the Mustang. We get that. So each bar is crafted by hand by master fabricators, TIG welded for the ultimate in durability, and custom powder coated in our facility (at no extra charge). We've color-matched powder to most of Ford's factory paint colors for a truly customized look, or you can choose from thousands of custom colors and finishes to give your car a personalized look that will last. Going from raw Docol tube stock to a gleaming finish, every roll bar is handcrafted by our most experienced cage- and race car builders. Nothing is left to chance. The CMS roll bar is designed to give you an unobstructed view through your rear window. None of your plastic interior trim needs to be removed or cut, just a little carpet that is hidden away. So if you ever need to put your car back to stock, it will look as though the roll bar was never there. Complete, detailed instructions make installation pretty simple (figure about two hours if you're reasonably handy; having a buddy helps!) All the supplied installation hardware is American made: Grade 8 mounting hardware and an industrial carbide drill bit. So you don't have worry that you don't have what you need for a flawless installation. You can add four-point or six-point harnesses to your Mustang (depending on the seats you're using) using the drop-downs above. Many customers also add CMS Locking Harness Collars to keep harness shoulder straps right where you want them (they're not required for safety, but a lot of people like the look!). CMS Performance Mustang Roll Bar Details: Materials: 1.75″ X .095" Docol R8 Advanced High-Strength Steel tubing Construction: Fully TIG welded for ultimate strength, integrity, and beauty. Design details: One-piece main hoop and three-piece rear kicker make installation simpler. Weight: 52 lbs. (23.6 kg) CNC-cut mounting plates. Designed, built, and powder-coated by CMS Performance in the USA. CNC machined high-strength steel interlocking clamps ease installation. Allows full seat travel with any seat. Straightforward install and perfect fitment, guaranteed. Includes all necessary hardware including carbide drill bit. Roll bar installation in the Mustang requires removal of the rear seats. This product is intended for off-road race track use only.
