Show original supplier description
The Swift SPEC-R Sport Springs are engineered to elevate the performance and visual appeal of your 2015-2021 Subaru WRX. They are crafted to maximize optimal suspension geometry while increasing spring rates, which are carefully calibrated to remain within the upper limits of the vehicle's factory shock valving. This ensures enhanced performance without compromising comfort for daily street use. With a focus on both performance and aesthetics, the SPEC-R springs offer a balanced 1-inch drop (approximately 25mm) at both the front and rear. This moderate lowering reduces wheel gap and contributes to a more aggressive stance. The front spring rate is 6.0 Kg/mm (335 Lbs/Inch), and the rear spring rate is 7.2 Kg/mm (402 Lbs/Inch), providing a stiffer, more responsive ride compared to stock. Customers have reported positive experiences with the Swift SPEC-R Sport Springs, noting a significant improvement in handling and a reduction in body roll, making the car feel more planted. While some users mention a slightly bouncier ride on rough roads, many find the overall ride quality to be a good balance between sportiness and comfort for daily driving. Installation is described as manageable, with recommendations for using impact and pass-through wrenches to ease the process. The product comes as a set of four SPEC-R springs and is backed by a manufacturer's standard warranty.
