ST XTA Plus 3 Coilover Kit Infinity G35 Coupe 3.5L / Nissan 350z Coupe (Z33) 3.5L

If you're looking to get the most out of your 2003-2008 Nissan 350Z or 2003-2007 Infiniti G35 Coupe, this ST XTA Plus 3 coilover kit from ST Suspensions is built to give you serious control over your suspension's performance. These aren't just basic lowering springs; they're a complete, high-performance suspension system designed for drivers who want to fine-tune their car's handling for the track or spirited street driving.

What sets this kit apart is the advanced damping adjustability. You get 24 distinct settings for both high-speed and low-speed compression, plus 18 settings for rebound. This means you can precisely dial in how your suspension reacts to different road surfaces and driving inputs, whether you're dealing with bumps, aggressive cornering, or even changes like adding a roll cage or different wheel loads. The kit includes linear race springs for consistent response and aluminum unibal top mounts that improve steering feel and allow for camber adjustments. The galvanized steel strut housings are built to last, with multiple seals to keep dirt and water out, ensuring longevity in all weather conditions.

Adjusting the ride height is straightforward thanks to the seamless thread on the galvanized strut housing and the composite spring perch, which is made from a wear-resistant, friction-optimized polyamide with a stainless-steel insert. This design prevents oxidation and makes adjustments easy, even with the kit installed. Each damper is built by hand at KW in Germany and tested on a shock dyno to ensure it meets performance standards before it's boxed up. This kit is a comprehensive solution for anyone serious about optimizing their vehicle's handling.
