Are suspension modifications worth the money? In this video we'll analyze how cars get grip, what impact suspensions play, and the test results from Tire Rack testing four different suspension setups: 1) Original equipment suspension on a BMW 3-series. 2) Lowering Springs. 3) Springs, dampers, and sway bars. 4) Coilovers (using stock sway bars). We'll discuss differences in noise, ride comfort, handling, cornering stability, steering response, braking modulation, handling predictability, cornering grip, slalom times, and lap times.

We'll also discuss why investing heavily in suspension setups can be worthwhile for racing teams, but often those reasons won't apply to road cars. Ultimately, it's important to understand what reasons make sense to upgrade a suspension, and where you might be let down. Modifications are always about setting realistic expectations and meeting your goals; I hope you find this video helpful!
