Sparco SPX Reclining Seat (non-FIA) The SPX is handcrafted in Italy using the same technology and materials used for OEM super cars. In fact, the SPX is the first carbon fiber reclining seat available to the public that meets the same specifications required by the OEM manufacturers. What this means is that the attention to detail and quality put into the SPX cannot be matched by any other seat manufacturer on the market today. The Sparco SPX seat represents the ultimate evolution of the sport seat. The SPX uses a combination of carbon fiber and advanced composites that give the driver both comfort and performance in a lightweight package. With the ergonomic shape of the carbon fiber backrest and the seating position of the RTM composite lower, the SPX holds the driver during extreme lateral forces and is comfortable for long road trips. The SPX is covered in a combination of beautiful perforated and smooth Italian leather. The center of the SPX is covered in Alcantara suede to allow you to gain absolute control of your vehicle and enhance your driving experience. To finish off the performance look, all hand stitching is done in tone-on-tone black with the Sparco logo embroidered in matching black. The gloss finished carbon fiber backrest features a leather pull strap which releases the backrest to fold forward to allow access to a backseat or storage area. The backrest also features a micro adjustment knob that allows you to dial in the perfect driving position. The SPX is sold in driver and passenger versions (left and right). TECHNOLOGY Lightest carbon fiber reclining seat on the market Gloss carbon fiber back rest RTM composite lower (an advanced composite with strength and weight similar to carbon fiber) Covered in hand-stitched Italian leather and Alcantara suede Leather pull for seat back release Sold in driver (left) and passenger (right) versions SPX DIMENSIONS A LITTLE HISTORY Sparco has designed and engineered some of the most advanced sport seats in the world, including the first-ever adjustable carbon fiber seat in 1998 for the Lamborghini Diablo. Since then, countless super cars such as the Bugatti Veyron and Lamborghini Aventador have used Sparco design and technology in their vehicles. In addition to seats, Sparco also produces carbon fiber body panels, bumpers, roofs and aerodynamic pieces, in addition to structural carbon fiber parts like stressed-member engine cradles and other chassis parts. Supplying OEM manufacturers requires every part to pass demanding safety and durability tests. Sparco’s extensive expertise in carbon fiber technology is why they're a Tier One supplier for Alfa Romeo, AMG, Aston Martin, Audi, Bentley, Bugatti, Ferrari, Koenigsegg, Lamborghini and Lotus to name a few.

Garmin Catalyst Driving Performance Optimizer DISCOVER YOUR FULL TRACK DRIVING POTENTIAL This device is an industry-first, providing virtual coaching in real time and showing a calculated optimal lap. Real time coaching tells you how to go faster in each corner, with audio instructions, so you can keep your eyes up at all times. This is a stark contrast to existing systems which only provide feedback after a corner or after your session. The Catalyst uses your measured optimal lap to guide you to your personal maximum performance, rather than the performance of a professional racing driver. OverviewGarmin Catalyst uses accelerometers, GPS, video, and the most sophisticated algorithms to evaluate your driving performance and then suggest ways to improve (just like a human coach). Through the display and audio, Catalyst provides a real-time assessment of performance using both gentle suggestions and positive reinforcement. No, it won't clap when you get it right but it does use real-world phrases and encouragement - such as "brake less", "apex later", or "keep pushing". Catalyst is perpetually evaluating and assessing your performance so it can optimize your lap and get you in line. After your session, review track maps showing opportunities for improvement as well as "heat map" displays of deceleration, acceleration, apexes, and speeds.Display & AudioCatalyst uses a 6.95" super wide view LCD IPS screen with vivid TFT colors. The LCD is a touchscreen, able to control functions without the need for a remote control, app, or a laptop. Coaching or playback audio is available via 3.5mm headphone jack or Bluetooth(TM) to your headset or car stereo. The on-screen layout is not programmable.CameraThis is more than just a camera - the remote pod includes the accelerometers. It records up to 30fps in 1080p HD in a 140° field-of-view. It must be mounted facing forward, high up, and centered on your windshield. An on-screen guide will help you align it. The camera contains the accelerometers and very powerful processing software integrates the video into Catalyst's coaching and data. Playback is available on the Catalyst screen with speed and lap times already in sync.CoachingTo unlock all of the coaching features and data you will need to select the Advanced setting. There is also a Basic setting that does not provide as much feedback. During your session, the real-time display is referencing current session data only. However, post-session review can include data from multiple sessions. Catalyst is looking for patterns in your driving to map out where you were fast and opportunities to try a different line, brake less, or carry more speed. The only voice currently available is a Siri-like female voice. Lap time differential is displayed as either red (slower), green (faster), or black (no change). From a student/novice perspective you may want to have an advanced driver/instructor set baselines in your car first. Then overlay that data with your own driving. This way Catalyst can see the full potential and make recommendations. It's important not to "chase" a lap time but to know what is capable and make incremental improvements to get there. Catalyst will never make a recommendation that hasn't been previously successful.Analysis & ReviewCatalyst compiles all of its data to form a True Optimal Lap. This is your best possible lap using all of the data you provided in your sessions. True Optimal Lap is determined not just by lap and sector times but by analyzing your best lines through corners and sectors and using the camera feed to identify track limits. Catalyst retains your track data over a 4-day period so you can pack in a full weekend of driving with progressive coaching and analysis. Post-session data is reviewed through the screen or through the Garmin Connect(TM) smartphone app, including video. Export of data or video files to a laptop is not currently supported nor is it needed. Everything you need is self-contained in the tablet. Catalyst works best when used as a standalone tool to review performance and make adjustments while at the track. IN THE BOX: Garmin Catalyst 32GB microSD pre-installed under covered compartment (auxiliary card slot on the side of the Catalyst device is externally accessible for memory expansion) Remote Cam with polarized lens cover Remote Cam 3.5 meter cable Heavy-duty vehicle suction cup Powered magnetic mount Two 1” connecting arms 1” arm connector Cable clips Socket power cable Documentation INCLUDED ACCESSORIES: One-inch ball adapter screw down mount USB data cable 12V bare wire vehicle power cable Additional Remote Cam adhesive Continue reading to see how and why the Garmin Catalyst Driving Performance Optimizer is unlike anything you've ever experienced. Heck... it's unlike anything you've ever even thought possible!

Thunderhill is an Authorized dealer for GiroDisc products and we are one of the largest stocking dealers in the country. We ship most products same or next business day to ensure we meet your delivery deadline. Fits Corvette C8 The GiroDisc system is a direct replacement for the OEM brake disc. The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly. By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency. The Giro Disc rotors are lighter than OEM pieces. The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and Thunderhill RF-1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron which is constructed in the USA and is made to the same specification with the same material used by professional racing organizations. The rotors curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by GiroDisc in the USA to our own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by grade12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The 2-piece GiroDisc design allows for rotor only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.
