Product Description

The TEIN VSK54-C1SA3-C Flex Z Coilover Kit is engineered specifically for the Infiniti Q50 and Q60 RWD platforms (2014-23 model years) with the 3.0L or 3.5L V6 engine. It gives drivers full adjustability of ride height and damping settings, allowing for aggressive stance or track-tuned feel while retaining comfortable everyday usability.

With a wide adjustment range (front up to approx. -3.9" and rear up to approx. -5.7"), the kit enables dramatic lowering while maintaining suspension functionality and stroke. The 16-way damping adjustment gives you the flexibility to dial the ride from relaxed daily driving to firm performance use. TEIN's twin-tube design and rigorous build quality ensure the unit performs reliably under different road and driving conditions.

Installation is direct-fit using your vehicle's factory mounting points, with additional camber adjustability up front to fine-tune alignment after lowering. A full alignment is recommended post-install. This kit is ideal for enthusiasts who want a performance-oriented suspension upgrade without resorting to fully custom fabrication. Fitment is confirmed for RWD versions; confirm trim/build (especially drivetrain) before purchase.
