First, you need to be clear about your purpose for modifying the car or the goal you want to achieve, such as making it a cornering beast, a straight-line monster, or simply for appearance. If it's purely for appearance, the only downside is that after lowering the body, the suspension geometry painstakingly set by the original engineers is disrupted, and the stress on suspension components changes, potentially making them more prone to damage, creating annoying noises, and other issues. If your goal is to improve handling, I advise you to either keep it stock or seek out highly professional individuals to modify your car. There's a saying in the modification world: 'Lower it, and a hundred flaws disappear.' This isn't entirely false. However, when browsing forums and communities, we often see many car enthusiasts who have lowered their cars mention that after lowering, they feel the handling has improved, lane changes feel more confident, and so on. The real reason isn't that the handling has improved but that lowering the body lowers the center of gravity, reducing the car's body roll. However, reduced body roll doesn't necessarily mean better handling. Good handling means that during turns, the tires maintain a larger contact patch with the road, providing stronger grip—that's what good handling is. After simply changing the springs and shocks to lower the car, theoretically, the handling should worsen. Why is that? Because the suspension geometry is compromised. Although body roll is reduced, giving a greater sense of security, the margin for error for the tires becomes smaller, meaning the window for recovery is narrower.
