MTS Technik Coilover Suspension Comfort / Inox – Honda Civic IV (EC/ED/EE) (XMTSGWHO04-C)
Product Overview
The MTS Technik Comfort Series Inox Coilover Kit (XMTSGWHO04-C) is a premium, height-adjustable suspension network explicitly valved for the 1987–1991 Honda Civic IV. Available at JDMaster.net, the Comfort Series is engineered for car enthusiasts who prioritize ride quality and daily usability over absolute stiffness. By matching shortened stainless steel dampers with custom-valved, compliant Eibach performance springs, this kit eliminates unappealing factory wheel gap while preserving smooth daily road mannerisms.
Key Features & Benefits
-
Comfort Series Calibration: Specifically tuned with softer, more compliant internal damping curves and progression rates compared to the standard Street or Stance setups. It absorbs harsh road imperfections cleanly, keeping your daily commute smooth and comfortable.
-
Inox Stainless Steel Struts: Built using high-grade stainless steel shock housings for elite, permanent corrosion protection. The adjustable sleeves resist road salt, mud, and water, ensuring threads spin freely years down the line.
-
Performance Springs by Eibach Germany: Equipped with custom-engineered main and helper springs manufactured by Eibach from high-tensile steel alloys. These springs maintain structural integrity and resist settling or sagging over time.
-
Patented anti-seize hexaCOIL Perches: Utilizes an innovative single hexagonal composite spring collar. The design naturally channels road grit away from the threads during ride height changes, preventing the frozen or seized collars common to legacy dual-locking metal designs.
-
Twin-Tube Gas-Oil Infrastructure: Low-pressure nitrogen gas compresses the internal hydraulic fluid reservoir to eliminate fluid cavitation and oil foaming during high-frequency piston cycles, maintaining stable damping force.
-
Practical Lowering Range: Fine-tune your classic Honda’s road presence with an adjustable drop spectrum of 25–70mm on the front axle and 20–65mm on the rear axle.
-
High-Density Polyurethane (PUR) Bump Stops: Advanced progressive bump stops cushion deep suspension compression smoothly, protecting your chassis and internal valving elements from sudden bottoming impacts.

The Mechanical Advantage: Smooth Compliance for the Classic Double Wishbone
The fourth-generation Civic and second-generation CRX are legendary among Honda purists because they feature a race-derived, highly precise 4-wheel double-wishbone suspension architecture. While this design yields fantastic mechanical grip, it offers relatively short vertical suspension travel. When lowering these cars on standard sports springs or overly stiff coilovers, the ride quality frequently degrades into a bumpy, bone-shattering experience that rattles the interior plastics.
The MTS Technik Comfort Series solves this vintage platform issue. By utilizing shortened, short-stroke twin-tube dampers valved intentionally for road compliance, the shocks allow the suspension to cycle smoothly through its travel range. Backed by dedicated helper springs on both axles to ensure constant spring preload even at a lower ride height, this setup controls body roll through corners while maintaining a supple, smooth, and predictable ride across rough asphalt.
Professional Installation & Alignment Advice
Clearances & Post-Install Alignment: Changing the ride height on the Civic IV double-wishbone network alters tracking, dynamic camber arcs, and toe angles. A professional 4-wheel laser alignment is strictly mandatory following installation to preserve straight-line stability and protect your tires from uneven wear.
Due to the wider barrel profile of aftermarket coilover springs relative to thin factory struts, a minimum clearance gap of 5mm must be verified between the inner wheel rim/tire sidewall and the coilover body. If you are running high-offset factory rims or aggressive aftermarket wheel fitments that drop below this 5mm threshold, high-quality hub-centric wheel spacers are required. Plan your build smoothly by booking an installation appointment at our fully equipped JDMaster.net workshop.
