降低车身不是换完弹簧就结束：安装、定位和日常可用性都要验收

Choose a suspension setup for real parking ramps, loads and routes, not only a static photograph. Document baseline heights and conditions, and use part-specific vehicle instructions. Springs contain hazardous stored energy; this article is not a removal procedure. Qualified installers should check component compatibility, routing, clearance and alignment. Assess whether the actual manufacturer's process requires affected driver-assistance calibration; it is not automatic for every car or every job. Keep measurement, installation and calibration records and follow the specified recheck plan. Investigate unusual noise, contact or steering changes rather than treating every fault as normal after modification.
