Understanding the 2004 Nissan 350Z Suspension System

Before diving into coilovers, it’s important to understand how the stock suspension works.

The 2004 Nissan 350Z uses:

• A front double-wishbone suspension
• A rear multilink independent suspension
• Front and rear sway bars
• Body-tuned factory spring rates
• Tokico or KYB-style OEM dampers, depending on trim

This suspension design is excellent for balance and gives the Z its signature responsive feel. However, the factory shocks and springs are not built for aggressive performance, nor are they designed to handle major lowering without negatively affecting ride quality or geometry.

That’s where 350Z coilovers come in.

What Are Coilovers and Why Are They Ideal for the 350Z?

“Coilover” is short for coil spring over shock absorber. Unlike separate OEM springs and shocks, coilovers integrate both into a single adjustable unit.

For a 2004 Nissan 350Z, coilovers provide:

✓ Ride height adjustment

You can raise or lower your Z precisely — from track-ready low to comfortable street height.

✓ Damping adjustability

Many coilovers allow:

• 24-way
• 32-way
• Even 36-way rebound/compression adjustments

This means you can fine-tune handling to your driving style.

✓ Improved cornering

Stiffer springs and performance dampers drastically reduce:

• Body roll
• Squatting
• Nose dive
• Instability at high speeds

✓ Better aesthetics

Lowering your 350Z improves stance dramatically — reducing fender gap and giving the car a more aggressive, planted look.

✓ Track-readiness

If you drift, autocross, or road race, good coilovers are essential for consistent grip and weight transfer.

Why Coilovers Are the Best Suspension Upgrade for a 2004 Nissan 350Z

Most 2004 350Zs on the road today have worn factory shocks due to age. This causes:

• Bouncy ride
• Poor responsiveness
• Uneven tire wear
• Reduced traction

Installing fresh coilovers solves all of these problems while adding performance benefits OEM suspension never offered.

Coilovers also give you complete control over:

• Spring preload
• Ride height
• Damping settings
• Geometry balance

This makes them the best suspension upgrade for daily drivers and track builds alike.

The 350Z handles extremely well when lowered moderately, but lowering too much can cause geometry issues without supporting mods.

2. Damping Adjustability

More damping levels = more control.

Look for:

• 24-way
• 32-way
• Or multi-phase adjustable systems

This allows you to soften the ride for city driving or stiffen it for the track.

3. Spring Rates

Common spring rates for the 350Z:

• Street: 8k/6k
• Sport: 10k/8k
• Track: 14k/12k or higher

Higher rates = stiffer ride but better performance.

4. Camber Plates

Front camber plates are extremely useful for:

• Proper wheel alignment
• Drifting setups
• Stance builds
• Track handling

Many coilovers include these on the front, while some also include rear adjustable arms.

5. Build Material

High-quality coilovers use:

• Forged aluminum mounts
• Carbon-steel shock bodies
• Monotube dampers for consistent performance

Avoid unbranded coilovers with unknown metal quality.

6. Warranty & Rebuildability

Good brands offer:

• 1–3 year warranties
