If you're looking to up your track game and go faster, a lap timer can be a big help. Most car lovers also love going fast, and while the casual exhilaration of speed on a perfectly twisting road or the accomplishment of tackling a tough trail are enough for many of us, the more driven feel the need to go faster. You can make a car faster with more power or better suspension, but the best (and cheapest) performance upgrade that you can make is to the component between the seat and the steering wheel: you, the driver. One of the best tools to help you become a faster driver is a precise lap timer. While that can be as simple as setting a stopwatch at the start of each session, most dedicated racing lap timers use GPS technology to automatically mark each lap's beginning and end, separating the time for each and allowing the user to see how changes to your racing line and braking points affect your overall speed and RPM. The best examples also log and save your sessions digitally -- often along with vehicle performance test data or video -- for review later.
