==Overview== thumb|1971-1976 Chevrolet Caprice#Second generation (1971–1976)|Chevrolet Caprice convertible "Donk" on Forgiato wheels with custom paint, grille, headlights, and interior Hi-risers originally grew out of the Dirty South subculture, but the trend has spread across the United States. Vehicles customized in this style are distinguished by their oversized wheels, ranging from 20 inches to 30 inches or more in diameter (with the largest being 50 inch). A number of wheel companies make wheels in larger sizes specifically for hi-risers, including Asanti, Dub, Forgiato, Lexani, and more. 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. Other common modifications include custom paint-jobs, interiors, headlights, and trim; custom audio equipment; engine swaps and other performance upgrades; steering wheels that match the design of the wheels; and radiused fenders to fit the larger wheels. Other names for hi-risers and donks include "skyscrapers" due to their height, as well as simply being referred to as "big rim" or "big wheel" cars by people within the community.
