Tein Street Basis Z Coilovers - 04-08 Acura TSX Street Basis Z Coilover Kit

The Tein Street Basis Z Coilovers are some of the best cost-effective and quality set of coil overs on the market. This is a great suspension system for those who want something more aggressive than lowering springs. The Street Basis coil overs supersede Tein's Basic coil over design made with improvements in design and performance. These coil overs feature steel construction with twin tube internal components. These components include a larger piston diameter for the front and rear struts.  These are height adjustable for those of you who want to improve the center of gravity in their vehicle, but to also provide the vehicle with a more pronounced look especially if you are equipped with a more aggressive wheel. These coil overs will come with 1-piece aluminum springs and they will come finished in Tein's flagship green color for extra protection against rust and corrosion. With the Tein Street Basis Coil overs, you will be using your factory top hats to complete the installation.   Features: - Full-length ride height adjustment feature - Twin-tube structure - Ride height adjustment with little or no change in ride quality - Complete suspension kit of 4 shock absorbers and 4 springs Optimal Dust Boot Thanks to its smooth compression and high durability, the dust boot guards the piston rod from damage, and keeps foreign material out of the shock absorber.(Some vehicles use their OE dust boots) No-Sag Spring Cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm2), our springs are outstandingly sag-proof and boast extreme resiliency. Superior rust protection is ensured with a highly durable powder coating that does not peel or flake. Our high-quality springs can be used without worries, in any conditions. High-Performance Damper Oil Since TEIN's damper oil maintains a stable viscosity in a broad temperature range, it sustains smooth stroke and reliable damping force in a variety of circumstances. Due to excellent anti-foaming properties, it's resistant to cavitation (bubble forming). Since it withstands high heat too, it's suitable for intense sport driving as well. Furthermore, the damper oil keeps up its superior performance long-term, because it's resistant to deterioration over time. Rust-Proofing TEIN-Green Powder Coating A bright TEIN-green powder paint is used on the shock absorber's shell case. Our powder coating technique produces an extremely strong and durable barrier. No harmful organic solvents are used, for minimal pollution. Superior durability and corrosion resistance are achieved by TEIN's patented 2-Layer, 1-Bake powder coating method, which uses 2 layers of anti-rust paint on a blasted surface.(Japanese patent number 4347712) Special Surface Treatment 'ZT Coating' Our unique ZT Coating surface treatment on the ride height adjustment thread is abrasion resistant against gravel/debris, and further enhances its corrosion resistance. With zero claims for stuck parts due to rust in 500,000 shock absorbers, TEIN shock absorbers are amazingly rustproof. We're confident of customer satisfaction even in coastal areas or regions with heavy snowfall.
