Improve the handling, stance, and overall driving experience of your 2007–2008 Honda Fit (GD3) with the Swift Sport Lowering Spring Kit, Part #4H912. Developed specifically for the first-generation U.S.-market Honda Fit, these springs provide a noticeable reduction in ride height while maintaining the comfortable and responsive characteristics needed for a daily-driven street car.
Swift specifies a 3.0 kgf/mm front spring rate and 5.6 kgf/mm rear spring rate, along with approximately 1.2 inches of front lowering and 1.0 inch of rear lowering. The result is reduced wheel gap, a lower center of gravity, and improved chassis response without an excessively low ride height.
Swift's Sport Springs are developed around the usable suspension stroke of each specific vehicle rather than simply using an aggressive drop for appearance. This approach helps preserve suspension travel and ride quality while reducing body roll and improving overall handling balance.

Sport Springs Designed for Street Performance
- Swift developed its Sport Spring Series around three primary goals: maintaining or improving ride comfort, increasing handling performance by reducing body roll and squat, and lowering the vehicle while staying within the suspension's usable stroke.
For the lightweight GD3 Fit chassis, this makes the 4H912 an excellent choice for enthusiasts who want a more responsive suspension without immediately moving to a complete coilover setup.
Works with Factory Dampers
- The Swift 4H912 Sport Springs can be used with the factory shocks and struts, making them a straightforward suspension upgrade for otherwise stock vehicles. They can also be paired with compatible performance dampers for owners looking to further refine their suspension setup.
Installation Note
- A professional alignment is recommended after installation. Lowering the vehicle changes suspension geometry, and proper alignment helps ensure predictable handling and even tire wear.
- Vehicles equipped with aggressive aftermarket wheel and tire combinations should also be checked for adequate tire-to-fender and suspension clearance after installation.
The Swift 4H912 Sport Lowering Spring Kit is an excellent upgrade for the 2007–2008 Honda Fit GD3, delivering a balanced combination of improved handling, reduced body roll, approximately one inch of lowering, factory-damper compatibility, and street-friendly ride quality.
