Hi-risers originally grew out of the Dirty South subculture, but the trend has spread across the United States. Vehicles customized in the hi-riser style are distinguished by their over-sized (even disproportionate) wheels, ranging from 20 inches to 30 inches or more in diameter (largest being 50 inch), as well as fanciful custom paint-jobs and expensive audio equipment. Suspension modifications similar to those employed on lifted pickup trucks are made to give adequate clearance for the large wheels. Often the suspension is modified so the front end sits slightly higher than the rear end, giving the car a swaggering appearance. Because of the exaggerated look gained from installing a lifted suspension and enormous wheels, donks are also known as "hi-risers" or "skyscrapers."
