The Complete Guide to Buying Import Suspension Parts

When you drive an imported vehicle—whether it's a Japanese sports car, a German sedan, or a Korean compact—the suspension system is often the first area where owners want to upgrade or replace worn components. Import suspension parts include everything from struts and shocks to control arms, coilovers, and sway bars. Choosing the right parts can improve handling, ride comfort, and longevity. This guide covers what you need to know before buying, key brands, and how to match parts to your driving style.

Understanding Import Suspension Systems

Import cars often use suspension designs that differ from domestic models. Common setups include MacPherson struts on many front-wheel-drive imports and multi-link rear suspensions on newer vehicles. Knowing your car's specific layout is critical when ordering parts.

MacPherson Strut vs. Double Wishbone

• MacPherson strut: Common on most imports (Honda Civic, Toyota Corolla, VW Golf). Simple design, but replacing struts often requires a spring compressor.
• Double wishbone: Found on performance imports like Acura Integra, older BMWs, and some Lexus models. Offers better camber control but more complex to service.
• Multi-link: Used on many modern sedans and SUVs (Mazda6, Audi A4). Provides a good balance of comfort and handling.

Key Components You'll Replace

• Shocks/Struts: Dampen oscillations. Struts are structural; shocks are not.
• Coil Springs: Support weight and determine ride height.
• Control Arms: Connect the wheel hub to the frame; bushings wear out.
• Sway Bars: Reduce body roll during cornering.
• Ball Joints and Tie Rod Ends: Critical for steering and alignment.

OEM vs. Aftermarket Import Suspension Parts

You have two main routes: Original Equipment Manufacturer (OEM) parts from the car's brand or aftermarket components from specialty companies.

OEM Parts

• Pros: Exact fit, factory ride quality, reliability.
• Cons: Expensive, often no performance upgrade.
• Best for: Daily drivers where comfort and longevity matter most.

Aftermarket Parts

• Pros: Wider price range, performance options (lower, stiffer, adjustable), often better durability.
• Cons: May require modifications, can be harsh on rough roads, quality varies.
• Best for: Enthusiasts wanting improved handling, lowered stance, or track capability.

Types of Aftermarket Import Suspension Parts

Coilover Kits

Coilovers combine a shock and spring into one unit, allowing adjustable ride height and sometimes damping. They are popular for tuner cars (Subaru WRX, Nissan 240SX, BMW E36).

• Street coilovers: Offer moderate lowering (1-2 inches) and comfort. Examples: BC Racing, KW Street Comfort.
• Track coilovers: Stiffer, lower, with extensive adjustability. Examples: Ohlins, KW ClubSport.
• Air suspension: For extreme lowering and adjustable ride height on demand. Bagged imports (like Infiniti G35) use air struts.

Lowering Springs

A cheaper way to lower your car. They replace only the springs, using your existing shocks. They can wear out shocks faster if not matched properly. Brands like Eibach and H&R are common.

Performance Shocks and Struts

• Twin-tube: Standard for daily driving. Good balance of comfort and control.
• Monotube: Better heat dissipation, more consistent damping, preferred for performance. Brands: Bilstein, Koni.

Control Arms and Bushings

Worn bushings cause clunks and poor alignment. Polyurethane bushings (Energy Suspension) last longer than rubber but transmit more NVH. Adjustable control arms allow camber correction after lowering.

How to Choose the Right Import Suspension Parts

Step 1: Define Your Goal

• Daily driving: Focus on comfort and durability. OEM or quality aftermarket shocks (Bilstein B4, KYB Excel-G).
• Occasional spirited driving: Lowering springs with matching shocks (e.g., Eibach Pro-Kit + Koni Sport).
• Track or autocross: Coilovers with adjustable damping and camber plates.
• Show car stance: Air suspension or extreme lowering springs (be aware of drivability trade-offs).

Step 2: Check Compatibility

Not all parts fit all years and trims. Use your vehicle's exact model year, engine, and drivetrain (2WD vs. AWD). Many import parts are specific to chassis codes (e.g., E46 for BMW 3 Series, S13 for Nissan 240SX).

Step 3: Set a Budget

• Budget (under $500): Lowering springs, basic shocks/struts.
• Mid-range ($500–$1500): Entry-level coilovers (BC Racing, Tein), better shocks (Bilstein B6).
• Premium ($1500+): High-end coilovers (Ohlins, KW), complete suspension kits.

Step 4: Research Brand Reputation

Stick with established names: KYB, Bilstein, Koni, Eibach, H&R, BC Racing, KW, Ohlins, Whiteline, Moog (for OEM-grade parts). Avoid no-name brands from unknown sellers—they often have poor quality control and no support.

Installation Tips for Import Suspension Parts

• Get an alignment after any suspension change. Even minor height adjustments affect toe and camber.
• Replace hardware (nuts, bolts) if they are corroded or single-use (often required by German cars).
• Consider camber kits if lowering more than 1.5 inches—imports usually need adjustable upper control arms or camber bolts.
• Torque to spec: Use a torque wrench for all bolts; under- or over-tightening can cause failure.
• Beware of rust: Japanese and Korean cars from the 90s and early 2000s often have seized bolts. Use penetrating oil and heat if needed.

Final Recommendation

For most import owners, upgrading the suspension offers huge driving benefits. If you drive a daily commuter like a Honda Accord or Toyota Camry, start with a set of KYB Excel-G shocks and fresh strut mounts. That restores factory handling without breaking the bank. For an enthusiast with a Subaru WRX or BMW 3 Series, a set of BC Racing coilovers (BR Series) provides a great balance of adjustability, performance, and value. Always pair any suspension change with performance tires and an alignment. Avoid cheap unknown brands; they compromise safety and ride quality. Stick with proven manufacturers that serve the import community, and you'll enjoy a better driving experience for years to come.
