What torque range and drive size do I need?

For lug nuts and most suspension/brake work, a 1/2-inch drive in the 25-250 or 50-250 ft-lb band is the common pick among reviewers. For smaller fasteners on bikes, motorcycles, and engine internals, a 3/8-inch (or 1/4-inch) drive with a lower range is more appropriate, since high-capacity wrenches can't accurately reach small values.
