In the past, finding the optimal chassis, driveline, gear ratios and other characteristics for desired street or drag strip performance was an expensive process characterized by trial-and-error. But with DragSim5 you can assemble and test the performance of any vehicle imaginable on any 1/8 or 1/4 mile strip. A pop-up Time Slip provides an easy to read visual summary of the overall vehicle performance. Also included is the sophisticated Traction Calculator that optimizes tire-track modeling and improves overall simulation accuracy.
