Honda Civic IV (1988–1991) – Suspension, Shocks & Springs

The suspension system of the Honda Civic IV (EF/ED, 1988–1991) has a major impact on handling precision, ride comfort and stability during dynamic driving. This category includes carefully selected components for street use, OEM+ builds and lightly tuned cars: KYB shock absorbers, Bilstein performance shocks, Eibach Pro-Kit lowering springs, AP Sportfahrwerke coilovers and polyurethane shock mounts. All parts are fully compatible with the lightweight multi-link suspension layout that makes the EF chassis so iconic.

KYB Shock Absorbers – OEM-like comfort and reliability

KYB (Kayaba) shocks are an excellent choice for daily-driven Civic IV models. They offer a characteristic similar to the original Honda suspension while providing improved durability and control. Perfect for D-series and B16A1 engines in stock configuration.

• smooth and controlled damping,
• long service life with consistent performance,
• ideal for OEM and OEM+ suspension setups.

Bilstein – sport-oriented B6/B8 performance

For drivers looking for sharper handling and higher stability at speed, Bilstein B6/B8 (depending on EF availability) offer a stiffer, more controlled ride. They minimise body roll, reduce dive when braking and significantly improve cornering behaviour.

• excellent thermal resistance in spirited driving,
• crisp response on turn-in,
• perfect match for progressive Eibach Pro-Kit springs.

Eibach Pro-Kit – lowering springs with improved stability

The Eibach Pro-Kit spring set provides a subtle, tasteful drop and noticeably better stability without sacrificing comfort. Thanks to progressive winding, the springs stay compliant on small bumps while stiffening during dynamic manoeuvres.

• typical drop around 25–35 mm,
• sportier stance and reduced body roll,
• excellent synergy with KYB and Bilstein shocks.

AP Sportfahrwerke Coilovers – adjustable height & sharper handling

The AP Sportfahrwerke coilover kit is a great upgrade for EF owners wanting height adjustability and a more direct suspension feel. It provides improved control in corners while still being comfortable enough for everyday use.

• height adjustment for OEM+ and sporty setups,
• stiffer characteristics for precise handling,
• suitable for daily driving and weekend spirited driving.

Polyurethane Shock Mounts

Polyurethane top mounts significantly stiffen the connection between the shock absorber and the chassis. They reduce excessive deflection found in old rubber mounts and substantially improve steering response and rear-end stability. Ideal for lowered or performance-oriented EF builds.

Why upgrading the suspension matters in the Civic EF

• restores confidence in cornering and fast lane changes,
• reduces body movement typical for worn suspension,
• improves braking stability and traction,
• brings back the sharp, lightweight handling that made the EF legendary.

FAQ – Honda Civic IV Suspension

Are KYB shocks compatible with lowering springs?
Yes, for mild lowering such as Eibach Pro-Kit. For more aggressive drops, Bilstein or AP coilovers are recommended.

Are AP Sportfahrwerke coilovers daily-drivable?
Yes – they are tuned for street use and offer a balance between comfort and sporty handling.

Do polyurethane mounts reduce comfort?
Slightly, but they dramatically improve precision and feedback in both front and rear suspension.

Do Bilstein B6/B8 work with stock springs?
Yes, but they perform best with progressive lowering springs like Eibach Pro-Kit.
