MTS Technik Coilover Suspension Street / Inox – Honda Civic VIII (FN/FK)

MTS Technik Coilover Suspension Street / Inox – Honda Civic VIII (FN/FK) (XMTSGWHO06)

Product Overview

The MTS Technik Street Series Inox Coilover Kit (XMTSGWHO06) is a premium, height-adjustable suspension package engineered explicitly for the 2005–2012 Honda Civic VIII Hatchback. Available at JDMaster.net, the Street Series serves as the definitive all-around upgrade layout recommended by MTS Technik engineers. This kit replaces tired factory dampers with a perfectly calibrated sport setup paired with Eibach performance springs—delivering flat cornering and immediate steering response while preserving the everyday road compliance needed for smooth daily commuting.

Key Features & Benefits

• Street Series Calibration: Meticulously valved to blend performance driving with everyday utility. It eliminates severe high-speed body sway and nose-dive under hard braking without subjecting you to a harsh, bone-shattering track ride.

• Inox Stainless Steel Struts: Built using high-grade stainless steel shock housings for elite, long-lasting corrosion defense. Strut threads stay clean and adjustable through rain, mud, and winter road salt.

• Performance Springs by Eibach Germany: Pre-assembled with custom-wound sports lowering springs from Eibach. Utilizing high-tensile steel alloys, these springs deliver precise, uniform rates that completely resist sagging over seasons of intense driving.

• Patented anti-seize hexaCOIL Perches: Utilizes an innovative single hexagonal composite spring collar. The design channels road grit away from the threads naturally during ride height adjustments, preventing the frozen or completely seized collars common to legacy dual-locking metal systems.

• Twin-Tube Gas-Oil Infrastructure: Low-pressure nitrogen gas actively compresses the hydraulic fluid reservoir. This layout eliminates fluid cavitation and internal foaming during high-frequency piston cycles to maintain uniform damping force.

• Flexible Lowering Range: Take complete authority over your vehicle’s stance with a smooth, adjustable drop spectrum on both axles to perfectly level out your wheel arches and dial in clean fitment.

• High-Density Polyurethane (PUR) Bump Stops: Advanced progressive bump stops smoothly cushion the internal piston assemblies during deep compression strokes, shielding your internal valving from sudden surface impacts.

Technical Specifications

The Mechanical Advantage: Fixing the FN/FK Torsion Beam Quirk

The eighth-generation Civic hatchback marked a massive mechanical shift for Honda, adopting a space-saving MacPherson strut configuration up front paired with a rigid, semi-independent torsion beam setup at the rear. When lowering this specific platform on standard lowering springs alone, the rear axle can feel uncomfortably stiff, crashy, and unsettled over mid-corner bumps because the factory shock absorbers instantly run out of functional travel.

The MTS Technik Street Series corrects this engineering flaw by pairing short-stroke, twin-tube gas shocks with a dedicated progressive Eibach spring and helper spring setup. By maintaining constant preload on the springs even during rapid weight shifts or deep extension, this kit keeps the rear beam compliant over road seams while pinning the front end down, restoring the nimble, direct, and playful go-kart steering handling that Honda enthusiasts love.

Professional Installation & Alignment Advice

Clearances & Post-Install Alignment: Altering the ride height on the Civic VIII modifies tracking, steering axis inclination, and toe arcs. A professional 4-wheel laser alignment is strictly mandatory immediately following installation to safeguard your performance tires and guarantee straight-line stability at highway speeds.

Due to the optimized, performance-oriented profile of aftermarket coilover springs, a minimum clearance gap of 5mm must be checked between the inner tire sidewall/wheel rim and the coilover body. If you are running high-offset factory rims or aggressive custom wheels that reduce this gap below 5mm, high-quality hub-centric wheel spacers are required.
