Sway Bars (Front + Rear)

Adjustable sway bars deliver the biggest handling upgrade for under $500: they cut body roll by up to 50% compared to stock bars, without sacrificing ride comfort over bumps like stiffer springs do. Unlike polyurethane bushings that only fix deflection, sway bars let you actively tune cornering balance — a stiffer front bar adds understeer, a stiffer rear adds oversteer. Data from Whiteline and Eibach confirms that cars with aftermarket sway bars achieve up to 0.05g higher lateral grip on skidpad tests.
