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

MTS Technik Coilover Suspension Street / Inox – Honda Civic VIII (FN/FK) (XMTSGWHO05)

Product Overview

The MTS Technik Street Series Inox Coilover Kit (XMTSGWHO05) is a premium, height-adjustable suspension system optimized specifically for petrol-powered eighth-generation Honda Civic hatchbacks. Available globally at JDMaster.net, the Street Series is the default, most popular setup engineered by MTS Technik. It replaces worn factory assemblies with a perfectly balanced sport-tuned network—delivering a flat, composed stance and immediate turn-in agility without causing an uncomfortably harsh, rigid ride during your daily street commutes.

⚠️ Important Kit Fitment Selection: The XMTSGWHO05 kit features a targeted spring calibration and valving profile engineered specifically for the lighter Petrol engine variants (1.4L / 1.6L / 1.8L). If your eighth-generation build is equipped with the significantly heavier 2.2L i-CTDi Diesel engine or the high-revving Type R (FN2), please select part number XMTSGWHO06 instead to ensure correct axle weight distribution.

Key Features & Benefits

• Street Series Calibration: Meticulously engineered to blend daily driver compliance with dynamic sports handling. This kit controls severe chassis weight transitions and dampens high-speed bounce without subjecting your passengers to a punishing track ride.

• Inox Stainless Steel Struts: Built with high-grade stainless steel shock housings to provide elite, permanent defense against wet road conditions, mud, and winter road salt—ensuring your alignment threads spin cleanly for easy adjustments season after season.

• Performance Springs by Eibach Germany: Pre-assembled with custom sport lowering springs wound out of high-tensile steel by Eibach. These springs provide uniform load support and exceptional settling properties that completely resist sagging over time.

• Patented anti-seize hexaCOIL Perches: Employs an innovative single hexagonal composite spring collar. The design naturally sheds road grit from the threaded bodies during height changes, 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 premium hydraulic fluid reservoir. This layout eliminates fluid cavitation and internal foaming during high-frequency piston movements, providing predictable damping profiles.

• Dynamic Ride Height Adjustments: Take full authority over your vehicle’s stance with an adjustable lowering range of 25–55mm on both the front and rear axles to perfectly dial in your wheel-to-fender fitment.

• High-Durability Polyurethane (PUR) Bump Stops: Upgraded progressive bump stops cleanly absorb extreme suspension compression strokes, safeguarding internal valving elements against harsh bottoming forces.

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

The eighth-generation Civic hatchback marked a massive design shift for Honda, introducing a space-saving MacPherson strut configuration up front paired with a rigid, semi-independent torsion beam axle 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 quickly run out of functional travel.

The MTS Technik Street Series solves this specific engineering hurdle by engineering short-stroke, gas-pressurized twin-tube shocks paired directly with a progressive Eibach spring layout. By keeping the spring firmly preloaded even during rapid weight shifts or deep suspension droop, this kit flattens out cornering lean, settles the chassis immediately out of road dips, and delivers the direct, immediate front-end steering response that Honda enthusiasts celebrate.

Professional Installation & Alignment Advice

Clearances & Post-Install Alignment: Dropping your chassis ride height fundamentally alters steering toe arcs and tracking geometry on the eighth-generation platform. A comprehensive, professional 4-wheel laser alignment is strictly mandatory immediately following installation to guarantee highway tracking stability and protect your performance tires from uneven wear.

Due to the performance profile of aftermarket coilover springs relative to thin factory struts, a minimum clearance gap of 5mm must be maintained between the inner wheel rim/tire sidewall and the coilover body. If you are running high-offset original wheels or aggressive aftermarket setups that drop below this 5mm threshold, high-quality hub-centric wheel spacers are required.
