What are the advantages of a double ball joint suspension?

The advantages of a double ball joint suspension: 1. It can reduce body roll and suppress brake dive; 2. It can improve steering precision. The double ball joint suspension is an improved version based on the MacPherson suspension. This suspension replaces the L-shaped control arm of the MacPherson independent suspension with two links, creating two connection points between the suspension and the steering knuckle, hence its name. The double ball joint suspension can enhance vehicle handling. The more connection points between the suspension and the steering knuckle, the better. The double ball joint suspension has one more connection point than the MacPherson suspension, so vehicles equipped with this suspension offer superior handling. Common independent suspensions found in cars include the double ball joint suspension, MacPherson suspension, multi-link suspension, double wishbone suspension, and double transverse arm suspension.
I've driven cars with double-wishbone suspension, and the biggest advantage I felt is the super-responsive steering, especially during high-speed turns where the body doesn't sway much, and the tires grip the road tightly, reducing the risk of skidding. On bumpy roads, this suspension also absorbs shocks well, minimizing body jolts and enhancing a sense of control and safety. I particularly love its performance in daily driving—there's minimal steering play, and the feedback through the steering wheel is clear, allowing me to better control the vehicle and avoid accidents on slippery surfaces. In congested urban traffic, it responds promptly, with acceleration and turns feeling rock-solid. Additionally, the lightweight suspension design helps save some fuel, making it feel like a worthwhile long-term investment, especially for those who enjoy driving pleasure.
