Whiteline 17-20 Honda Civic Si / Type-R Grip Series Kit

Starting with 4.2kg/mm front springs and 3.8kg/mm rear springs, this Whiteline Grip Series Stage 1 kit is built to give your 2016-2021 Honda Civic Si or Type-R a noticeable handling improvement. The springs are designed to lower the vehicle by 35mm all around, giving it a more aggressive stance while also contributing to a lower center of gravity for better cornering. This kit isn't just about springs, though; it also includes Whiteline's signature adjustable sway bars and drop links, which are key to reducing body roll during spirited driving.

The front and rear sway bars are both 24mm with two points of adjustment, allowing you to fine-tune the car's balance to your preference or the driving conditions. Whiteline uses advanced synthetic elastomer bushings for their sway bar mounts, which are designed to resist oil, grease, and weathering, ensuring long-term performance. These bushings also feature internal knurling and grease retention lips for optimal lubrication. The kit also includes sway bar links and mounting accessories, all designed for a straightforward installation that helps eliminate preload and allows for on-car adjustments.

Beyond the core components, the kit incorporates features like DIY lateral locks to prevent sway bar shifting and heavy-duty steel ball joints in the links for maximum strength and durability. The springs themselves are progressive rate, meaning they offer improved performance during aggressive driving without making the ride too harsh for daily use. Everything is finished with a protective powder coating to resist corrosion and withstand tough conditions, ensuring this suspension upgrade looks and performs well for years to come.
