FL5 Alignment Results – Real Data Explained

A Honda Civic Type R FL5 recently came into Autosport Tyre World for a full setup after upgrading wheels and tyres.

Instead of talking about theory, this article explains real alignment data from this car — what was wrong, what was corrected, and how it affects the way the car drives.

Rear Toe – The Most Critical Issue

Before Adjustment

• Left Rear Toe: 3.9 mm
• Right Rear Toe: 3.2 mm
• Total Rear Toe: 7.2 mm

This level of rear toe is well outside the ideal range.

After Adjustment

• Left Rear Toe: 1.2 mm
• Right Rear Toe: 1.1 mm
• Total Rear Toe: 2.2 mm

The values were brought back into a controlled and usable range.

What This Means in Real Driving

Before alignment:

• rear end feels unstable
• car does not track straight under acceleration
• excessive tyre wear on inner edges

After alignment:

• rear becomes stable and predictable
• improved straight-line tracking
• more even tyre load distribution

Front Toe – Stability and Steering Feel

Before Adjustment

• Left Front Toe: -0.8 mm
• Right Front Toe: 0.0 mm
• Total Front Toe: -0.8 mm

This indicates slight imbalance and outward toe.

After Adjustment

• Left Front Toe: 0.5 mm
• Right Front Toe: 0.4 mm
• Total Front Toe: 0.9 mm

Adjusted to a slight toe-in configuration.

Real-World Effect

Before:

• steering feels light and slightly unstable
• less confidence at higher speed

After:

• steering becomes more stable
• improved straight-line confidence
• better return-to-centre feel

Camber – Grip Under Load

Front Camber (After)

• Left: -1°53′
• Right: -1°44′

Rear Camber (After)

• Left: -1°52′
• Right: -2°09′

What This Does

• improves cornering grip
• keeps tyre contact patch more consistent
• balances performance and tyre wear

This setup is slightly performance-oriented but still usable for street driving.

Caster – Steering Stability

Data

• Left: 7°30′
• Right: 7°18′

What This Means

• good steering return
• stable high-speed behaviour
• consistent steering feel

Why Alignment Matters More on This Setup

This FL5 is running:

• 18x10 +40 wheels
• 265 width performance tyres

Wider wheels and tyres increase grip, but also make alignment more sensitive.

Without Proper Alignment

• tyres wear unevenly
• grip is inconsistent
• steering feels off
• performance is reduced

With Proper Alignment

• full tyre contact is used
• grip becomes consistent
• car feels stable and predictable

Real Conclusion from This Car

The biggest issue was not the wheels or tyres.

It was alignment.

Once corrected:

• handling improved significantly
• stability increased
• tyre wear was controlled

The Complete Setup

This vehicle now runs:

• 18x10 +40 wheels
• 265 performance tyres
• corrected alignment settings

All three elements work together as one system.

Where to Get Performance Alignment in Adelaide

For performance vehicles like FL5, alignment should be done based on:

• wheel size
• tyre type
• driving purpose

Autosport Tyre World provides alignment tailored to real-world performance setups.

Final Note

Alignment numbers are not just figures on a report.

They directly affect:

• how the car drives
• how tyres wear
• how much grip you actually get

Understanding alignment is key to getting the most out of any upgrade.

FAQ

Why do I need alignment after changing wheels?

Because wheel size and offset change suspension geometry.

What is the most important alignment setting?

Rear toe is often the most critical for stability and tyre wear.

Does alignment affect performance?

Yes, it directly impacts grip, stability and handling.

What happens if alignment is incorrect?

Uneven tyre wear, unstable driving and reduced grip.

Is alignment more important for wider tyres?

Yes, wider tyres are more sensitive to alignment changes.

How often should alignment be checked?

After any wheel or tyre upgrade, or when tyre wear is uneven.
