Overview

The Swift Spec-R lowering springs are a high-performance suspension upgrade designed specifically for 2012–2015 Honda Civic Si coupe and sedan models. These springs enhance vehicle handling by reducing body roll and improving steering precision while maintaining ride comfort for daily driving.
Show original supplier description
The Swift Spec-R lowering springs are engineered to elevate the handling and appearance of the 9th-generation Honda Civic Si platform. By providing a more stable and controlled feel during cornering, these springs address common body roll issues while sharpening overall chassis response for spirited driving. Technical specifications include a front spring rate of 4.7 kgf/mm and a rear rate of 5.4 kgf/mm. The installation provides a lowering drop of 1.2 inches in the front and 1.0 inch in the rear, achieving an aggressive aesthetic stance without sacrificing daily driving utility. This kit is compatible with 2012–2015 Honda Civic Si coupe and sedan models. Please note that these springs are specifically designed for this 9th-generation platform and are not for non-Si models or other vehicle configurations not listed. Professional installation is generally recommended to ensure proper spring seating and handling geometry.
