The 1991–1996 Buick Roadmaster is one of the most popular platforms in the world of Donk builds, lowrider culture, and custom wire wheel setups. Built on the legendary GM B-body rear-wheel-drive platform, it shares its foundation with icons like the Chevy Caprice and Cadillac Fleetwood, making it a perfect candidate for oversized wheels and custom suspension upgrades. Its strong chassis, wide wheel arches, and excellent clearance make it highly adaptable for 20-inch, 24-inch, and even 26-inch wire wheel builds when properly fitted.
