Land Rover Discovery
Series II, 1999–2004
Factory gearing, tires, angles and brakes for the Discovery, and what the usual upgrades do to it. Every number is from the maker's own figures unless the calculators say otherwise. A few figures here are still waiting on a factory document; the calculators mark them.
