As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline.This ultra-lightweight Girodisc system upgrades the OEM brakes to a two-piece steel disc and aluminum hat. This two-piece "floating rotor" design will bolt directly to your Mitsubishi Evo front and work flawlessly with OEM calipers.Upgrading your brakes to these incredibly lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness. Much lighter than the OEM rotors, Girodisc rotors reduce rotational and unsprung mass giving you stronger braking and faster suspension response.Combined with Pagid or PFC performance brake pads and Thunderhill RF-1 brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving.The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc.The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc. These drive pins transfer braking load while maintaining axial and radial float between the disc and hat to allow for heat expansion. Anti-noise spring washers eliminate the noise typically associated with floating rotors.This two-piece Girodisc design allows for disc-only replacement, reusing the hat to minimize maintenance costs.Sold/priced per pair.

The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat.

GARMIN CATALYST LAP TIMER FRONT STOP WATCH IMAGE
Garmin Garmin Catalyst™ Driving Performance Optimizer $999.99
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!

To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one. This helmet will ship with signature required for delivery.

IPD Intake Plenum for Porsche 991.1 Carrera S/GTS/4S FITS: Porsche Carrera S (2011-2015) Porsche Carrera GTS (2014-2016) Porsche Targa 4S (2014-2016) Like most Carreras, the power output of this Porsche's 3.8L naturally-aspirated engine is controlled to meet a performance target that satisfies mass buyers but not necessarily the dedicated Porsche driving enthusiast. IPD helps scratch the proverbial performance itch for Porsche drivers looking to elevate the already visceral driving experience to the next level. The 3.8L engine in the 991 Carrera S, GTS, and 4S is relatively unchanged from the previous 997.2 Carrera S, continuing to employ the 82mm throttle body. IPD's new specifically-designed 3.8L DFI Carrera S intake plenum is a direct bolt-on upgrade that replaces the factory air distributor and utilizes all pre-existing factory hardware including that OE factory throttle body. INCREASED POWER & TORQUE ACROSS THE REV RANGE The improved IPD intake design creates increased air velocity and air speed resulting in impressive power and torque gains of 15 HP and 14 lbs-ft. at the wheels on an otherwise-stock 991 S. As with most IPD plenums, the bulk of the power gains are realized in the mid-range where they are most used and enjoyed. Unlike other mods, though, the IPD Plenum delivers net power gains across the entire rev range. Installation time is four to five hours and should only be performed by a qualified Porsche technician.

We ship most products same or next business day to ensure we meet your delivery deadline. Fits Chevy Corvette C5 with Z51 Package Fits Chevy Corvette C6 with Z51 Package This Girodisc system is a direct replacement for the OE brake rotors on all C6 Corvettes equipped with the Z51 package. They will also bolt onto non-Z51 C6s and all C5s with the use of the C6 Z51 caliper brackets (which can be purchased through a GM dealer). The disc will bolt directly to the car and work with OE calipers perfectly.. The two-piece floating rotor 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 brake bias is maintained as well as your ABS efficiency. Girodisc rotors are lighter than the cast iron OEM pieces. This reduction in rotational and unsprung weight allows for quicker acceleration and superior suspension response. When used with Pagid or PFC racing brake pads and Thunderhill RF1 racing brake fluid, you have an amazing solution to brake fade, overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft aluminum. The disc is manufactured from cast iron, constructed in the USA and 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 of eight to ten high-strength alloy steel drive pins manufactured by Girodisc in the USA to their own specifications; they are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining axial and radial float between the disc rotor and hat. The pins are secured by Grade 12 cap screws with hardened washers and mounted with anti-noise springs to allow for heat expansion while eliminating the rattle and noise associated with floating rotors. The two-piece Girodisc design allows for disc-only replacement as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.
