Tein 12-13 Honda Civic Si (FB6/FG4) Street Advance Z Coilovers

The Tein Street Advance Z coilovers use a twin-tube internal structure, a design that helps manage heat buildup during spirited driving. This setup is specifically tuned for the 2012-2015 Honda Civic Si models (FB6 and FG4 chassis), aiming to give you a noticeable improvement in handling without sacrificing too much ride comfort for daily use. They allow you to adjust both the ride height and the damping force, giving you control over how your car feels and performs on the road.

These coilovers are built with durability in mind, featuring a full-length adjustment system that lets you lower your Civic Si significantly while maintaining adequate suspension travel. The damping force can be adjusted across 16 levels, allowing you to fine-tune the suspension for different driving conditions, from smooth highways to twisty backroads. The upper mounts are often integrated, simplifying installation by including necessary components like pillow ball upper mounts for the front, which can help improve steering response. The powder-coated finish on the lower brackets and the zinc-plated damper bodies are there to help resist corrosion, keeping your suspension looking good and functioning well over time.

When installing these, you'll find that they are designed as a direct replacement for your factory struts and springs, meaning no welding or major modifications are typically required. This makes the installation process more straightforward. You'll want to ensure you have the proper tools for adjusting ride height and damping, and it's always a good idea to have your alignment checked after installing new suspension components to ensure optimal handling and tire wear.
