Garmin Catalyst Driving Performance Optimizer is built for performance-minded racers who expect more from their gear. Here's why it belongs in your setup: Garmin Catalyst Driving Performance Optimizer Realize 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 Garmin Catalyst uses your measured optimal lap to guide you to your personal maximum performance, rather than the performance of a professional racing driver. Catalyst Overview Garmin 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. Catalyst 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. More Than Just Another Camera This 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. On-Track Coaching To 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. Lap time differential is displayed as either red (slower), green (faster), or black (no change). You can have an advanced driver or 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. So, instead of "chasing" a theoretical lap time, you know what's possible with Catalyst helping you make incremental improvements to get there. Catalyst will never make a recommendation that hasn't been previously successful. Off-Track Analysis & Review Garmin Catalyst compiles all of its data to form a True Optimal Lap. This is your best possible lap using all of the data provided during your on-track 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 four-day period so you can pack in a full weekend of driving with progressive coaching and analysis. Post-session data is reviewed on the Catalyst screen or through the Garmin Connect smartphone app, including video. (Export of data and video files to a laptop is not currently supported nor is it needed.) Everything you need is self-contained in the Garmin Catalyst, which works best when used as a standalone tool to review performance and make adjustments while you're at the track. Included in the Catalyst Box: Garmin Catalyst 32GB microSD pre-installed in 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 12V socket power cable Full 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!

Yes, as long as the car is equipped with the factory Brembo brake package, these rotors fit both engines and trim levels. Are these rotors lighter than stock? Yes. The two-piece aluminum hat and iron ring design saves several pounds per rotor, reducing unsprung mass for sharper handling. Can these be used with OEM brake pads? Absolutely. Girodisc rotors are fully compatible with OEM or aftermarket performance pads designed for iron rotors. Are they suitable for daily driving? Yes. While designed for high-performance use, Girodisc rotors deliver quiet, smooth operation ideal for everyday driving. Upgrade your Kia Stinger GT or Genesis G70 with Girodisc rear rotors and experience improved response, reduced fade, and race-proven braking confidence every time you hit the pedal.
