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.
