2. Installation complexity: Installing this kit requires some mechanical skills and tools, and the process can be time-consuming. It may be best to have it installed by a professional to ensure proper alignment and ride height.

3. Ride comfort: A lowered ride height can reduce the amount of travel for the suspension, potentially resulting in a stiffer ride. This may not be ideal for daily driving, especially on rough roads.
