Sand cars and desert racers have embraced independent suspension for a long, long time. Many cars and trucks that go fast off-road have independent suspension front and rear. Most are fully custom so you won’t find inexpensive swappable parts in the junkyard, but the aftermarket has embraced several independent front suspension (IFS) designs found in trucks and SUVs (like this Toyota) and support them with long-travel or heavy-duty parts. Independent rear suspension (IRS) designs are also very tractable for high-speed off-road use, but few OEM production designs are up to the task of heavy off-road use. One exception might be VW Beetle IRS, which is used widely in racing and sand cars.
