DeskTop FastLap5™ accurately simulates the unimaginably complex interaction of forces, speeds, and accelerations generated by any stock, high-performance, or all-out race vehicle. A comprehensive step-by-step analysis of the interrelated physics is performed during every increment of vehicle motion (full analysis is completed 1000 times per second!). DeskTop FastLap5™ derives an optimum driving path, and determines the best braking points and forces, aerodynamics, throttle positions, transmission shift-up and shift-down points, steering input, driver corrections, and more! Further analysis determines the best possible elapsed time for any track. Change any component in seconds and run back-to-back tests to “home in” on the ultimate setup for any vehicle and track. Accurate, easy-to-use, state-of-the-art and great fun; DeskTop FastLap5™ is an awesome simulation that, we are sure, will become the most valuable addition to your racer’s toolkit.

DeskTop FastLap5™ incorporates ProRacing Sim Software’s new user interface built from the ground-up for Windows95/98/Me/XP or Vista. QuickAccess™ buttons and DirectClick™ menus that let you change parts simply by clicking on any component. Nothing could be easier!  Analyze vehicle speed, lateral or longitudinal G's, rpms, damper forces, suspension movement, tire loads, and much more. View race results in full-color graphics. All data and graphs can be printed (and previewed) in color on any Windows printer.

DeskTop FastLap5™ also includes a Track Window that provides an “overhead” view of real-time vehicle movement (showing all vehicle motion, including understeer, oversteer, and driver corrections!). Watch as your test vehicle traverses every straightaway and turn and remains fully synchronized with the comprehensive telemetry displayed on the results graphs. Zoom-in and out on both Track and Telemetry to uncover every nuance of vehicle performance. DeskTop FastLap5™ also provides a real-time G-G Diagram that graphically indicates the sum of all forces acting on the vehicle. Each dot on the G-G Diagram indicates the equivalent force on the vehicle at each 0.001-second throughout the timed lap. A quick glance reveals whether vehicle was able to maintain its maximum G “envelope” throughout the course. Use this data, and the extensive chassis-tuning information provided in the over 160-page, color, Users Manual, to build the ultimate vehicle for any asphalt, closed-course track.

Pop-Up Lap-Time Slip™ offers an instant summary of the performance potential of any vehicle.

DeskTop FastLap5™ also accepts DeskTop Dyno5 and DynoSim5 engine test files (you can also manually enter any engine power curves), it is possible to test various engine components and measure their on-track effects. Imagine changing a camshaft then running a track analysis of the new power curve in just minutes! In the time it takes for you to dream up a new combination, you can perform an "on track" test and analyze the results!

The Track Editor™: You can run any vehicle you design on any of the 40+ built-in tracks (includes many of the World’s best-known race courses). Or design any track you can dream up using a fully-graphic Track Editor™! This powerful “application” built into DeskTop FastLap5™ lets you construct any track with any number of turns, turn radii, straightaway lengths, track widths, and more. Simply place corner points and the Track Editor draws the interconnecting track. Set the corner radii, fine tune the track points, and take your test vehicle for a “spin.” Build any track from a parking-lot autocross to a multi-mile twister! Build an imaginary track, or precisely construct a real-world track for methodical testing. Either way, the Track Editor expands the modeling capabilities of DeskTop FastLap5™ to limits of your imagination!

DeskTop FastLap5™ is supplied with a full-color, 150-page, on-disk Users Manual (directly accessible from within the program) that details the features of this comprehensive simulation. DeskTop FastLap5™ runs on any IBM-compatible PC computer using Windows95/98/NT/2000/Me/XP or Vista.
