Description

The K-Tuned 4N906 Sport Springs are engineered for the 2009-2015 Infiniti G37 Coupe (also known as Q60). Designed with both performance and aesthetics in mind, these springs aim to enhance your vehicle's handling capabilities without significantly compromising ride comfort. They provide a noticeable drop in ride height, with a front drop of -1.3 inches and a rear drop of -1.0 inch. The spring rates are set at 10.3kgf/mm for the front and 9.7kgf/mm for the rear, contributing to a more responsive feel and improved cornering. These springs are intended to offer a balance between sporty performance and daily drivability, appealing to enthusiasts who seek a refined driving experience and a sportier stance for their G37 Coupe.
