Flatout SR Coilovers for 2014–2025 Lexus IS

Upgrade your Lexus IS with the Flatout Suspension SR Coilovers, engineered for drivers seeking improved stance, street comfort, and precise adjustability. Designed specifically for daily-driven performance, the SR system delivers controlled damping, smooth ride quality, and a clean lowered look without sacrificing comfort.

With a height adjustment range of 0.5” to 3” lower than OEM in both the front and rear, you can dial in the exact stance you want while maintaining proper suspension geometry. The system features dual height adjustment and 20-point rebound tuning, giving you full control over ride feel and responsiveness.

Each kit includes two front and two rear assemblies built around rebuildable monotube shocks with CNC machined high-flow aluminum pistons, stainless steel shims, and medium-weight synthetic shock oil for consistent damping performance. Linear rate springs provide predictable handling characteristics, while electro-plated steel cartridges enhance durability.

Front assemblies include radial bearings for precise steering feedback, and camber-adjustable pillowball upper mounts come standard for improved alignment control. Lower mounts feature brackets for proper sensor line routing. Individual replacement parts are available, and each system is backed by a 3-year warranty against defects. Built to order for quality assurance.
