Kart Chassis Setup vs Kart Chassis Setup PRO

Tell the app how your kart behaves through a corner and it tells you what to change on the chassis. No guessing, no forums, no depending on somebody in the pit having a good day. WHY THIS APP • Set up your chassis and fix oversteer, understeer and any other handling problem: tell it how the kart behaves and it tells you what to change. • Learn how to tune it: every piece of advice explains what each component is for, what changes you can make and what each one achieves. • For beginners who want to set up like a pro and learn the techniques along the way, and for advanced drivers, with detailed pressures and temperatures for each wheel. • Cold target pressure for 31 compounds, with the breakdown of why that number. • Tyre temperatures typed in from your Apple Watch, with gloves on. • Widgets and track mode: the pressure to set, big and high-contrast. • A notebook of karts and sessions that follows you through your own iCloud. • Send a session to your mechanic as data, not just a picture. • One-off purchase. No subscription, no ads, no account. HOW IT WORKS You pick the symptom — understeer, oversteer, hopping, sliding on all four — where it happens (corner entry or exit) and how strongly you feel it. The app crosses that with your pressures, your temperatures and the conditions of the day, and gives you a list of adjustments ordered by priority: where to start, what is worth trying and what to do if it persists. Every piece of advice comes with its explanation and illustrations: it is not a black box. COLD TARGET PRESSURE What do I set cold BEFORE going out so the session ends inside the tyre's window? It accounts for the compound, air and track temperature, track condition, grip and total weight, and shows what moved the number. 31 compounds: 9 brands plus generics by hardness for when yours is not listed. ON YOUR WRIST AND IN THE PIT Apple Watch: the moment you come in, type in the temperatures of the four tyres (inside, middle, outside) with the Digital Crown, before they cool. They land on your iPhone. The target pressure is on the watch and on the watch face. Home and lock-screen widgets show the pressure to set, and track mode turns it into a huge, high-contrast number with the screen at full brightness. THE NOTEBOOK It saves every session with its pressures, temperatures, conditions, tyre and the advice you were given. Add the laps and your best time: it is the only thing that really tells you whether the setup worked. Several karts, each with its chassis. And it follows you between iPhone and iPad through your own iCloud, private to you; the session you are working on stays on each device. FOR YOUR MECHANIC Send a session by link, QR code or file. Your mechanic opens it in the app, reads exactly what you saw and saves it to their notebook: nothing is applied on its own, and no names, notes or position travel with it. Still available as an image for WhatsApp. CATALOGUES 175 circuits from 25 countries, with position, length, layout type and abrasiveness where known. Tap Detect circuit and the app proposes the one you are at, only when you ask. 33 chassis models from 11 manufacturers. If yours is not there, type it in and it is saved all the same. CALCULATORS AND UNITS Gear ratio with the theoretical top speed of each combination, and air density with a reference you can save, with the pressure estimated from the circuit's altitude. PSI or bar, Celsius or Fahrenheit, kilos or pounds, switchable on the screen. HELP AND HONESTY Every screen has its own help, written by someone who has taken tyre temperatures in a paddock. The pressure windows come from tuner guides, distributors and the specialist press; when a figure is not confirmed, the app says so. One-off purchase. No subscription, no ads, no account of ours. Works with no signal, which is how most paddocks are.

This app using data about your current chassis setup, cold and hot tyre pressures, tyre temperatures, behaviour in corners, weather and race track conditions will give you some recommendations about how to adjust your chassis in order to resolve any set up problem which you have. For each advice, you'll find an explanation about the adjustment. Each explanation contains pictures to be more understandable The application is valid for all types of karts and for all karting classes (senior, cadet, junior). It's usefull for experienced or novice drivers. For experienced it'll be a second opinion about what's wrong with the chassis setup, and for novices it will teach them the secrets of the chassis adjustments and chassis setup The application contains four tabs, which are described next: • Chassis: on this tab, you can enter data on the configuration of your go-kart chassis, tires, location, weather, engine, gearbox, driver and ballast. For example: - front and rear height - front and rear width - front and rear hub length - front hub spacers - front and rear torsion bars - Toe In / Toe Out - Ackerman - Camber - Caster - front and rear bumpers state - rear axle stiffnes - rear bearings - sidepods state - 4th torsion bar - struts of seat - rain meister - seat type - seat size - seat position - tyre type - material of wheels - driver weight - ballast positions and weight - and more... • History: this tab contains the history of all your settings of go-cart chassis. If you something in your chassis setup or change the weather, race track, conditions - new settings data automatically will be saved in the history • Analysis: this tab contains three types of chassis behavior analysis - Driving analysis: you'll have to inform about how the driver feels the behaviour of the kart in corners. In section "Behaviour in corners" you'll have to enter information about what the driver is feeling of a go-kart chassis behavior (for example - understeering at entry of corners). These are the most important information used by the application to calculate the advices. You also should enter information about race track is clockwise or anti-clockwise, current weather and race-track conditions (automatic weather detection via the Internet is available). All elements are taking into consideration for calculations - Pressure analysis: you have to inform about the hot and cold pressures of each tyre, matherial of wheels (aluminium or magnesium), target tyre temperature, current weather and race-track conditions - Temperature analysis: you have to set in this screen the information about hot tyre temperatures in the inside, middle and outside of the patch of each tyre, matherial of wheels (aluminium or magnesium), target tyre temperature, current weather and race-track conditions - Temperature: you can set in this screen the information about hot tyre temperatures in the inside, middle and outside of the working surface Then click on the "Analysis" button and application will show you some recommendations related on which adjustments you can do to solve any problem in the chassis setup that you can be suffering. A screen with detailed information about the adjustment will be shown. For example: "Insrease front track width" or "Modify tyres pressures" (how much you should adjust your pressures) or change your driving style • Tools: on this tab, you can find useful karting utilities. Fuel calculator, for perfect fuel mixing. Weight and balance to get the perfect go-kart weight distribution. Air density and density altitude for carburetor setup (JETTING). And much more. The app let you use different measure units: ºC y ºF for temperatures, PSI and BAR for pressures, lb and kg for weights, millimeters and inches for length, mb, hPa, mmHg, inHg for atmospheric pressure, meters and foots for altitude, gallons, oz, ml and liters for volume.
