FL5 Alignment Numbers Explained – What They Actually Mean
A Honda Civic Type R FL5 recently had a full wheel alignment after a performance wheel and tyre upgrade.
Many customers see the alignment sheet but don’t fully understand what the numbers mean.
This guide breaks down the key values and how they affect the car.
Understanding the Alignment Sheet
The alignment report shows three key sections:
- Camber
- Toe
- Caster
Each one affects how the car drives in a different way.
Camber – Tyre Contact Under Load
Camber is the angle of the wheel when viewed from the front.
Negative camber means the top of the wheel leans inward.
From the report:
Front camber is around:
- Left: about -1.5°
- Right: about -1.4°
Rear camber slightly more negative.
What This Means
More negative camber:
- improves cornering grip
- keeps tyre flat during turns
- reduces outer edge wear in aggressive driving
Too much camber:
- increases inner tyre wear
- reduces straight-line grip
👉 This setup is slightly performance-oriented but still usable on the street.
Toe – Stability and Tyre Wear
Toe is one of the most important alignment settings.
It describes whether the wheels point inward or outward.
Before Adjustment
From the report:
- rear toe was significantly out
- total rear toe was excessive
👉 This can cause:
- unstable rear behaviour
- rapid tyre wear
- poor straight-line tracking
After Adjustment
Toe was corrected to:
- balanced left and right
- within specification
What Toe Does
Toe affects:
- straight-line stability
- steering response
- tyre wear
Small changes in toe make a big difference.
👉 Correct toe = stable and predictable car
Caster – Steering Feel and Return
Caster is the angle of the steering axis.
From the report:
- around 7°+ on both sides
- balanced left to right
What This Means
Higher caster:
- improves steering feel
- helps steering return to centre
- increases stability at speed
👉 FL5 already has strong caster from factory, which is good for performance.
Rear Toe – The Most Important Fix
One of the biggest improvements in this setup:
👉 rear toe correction
Before:
- uneven
- excessive
After:
- balanced
- within target range
Why Rear Toe Matters So Much
Rear toe directly affects:
- high-speed stability
- corner exit behaviour
- confidence under acceleration
Incorrect rear toe:
- makes the car feel unstable
- reduces traction
Alignment + Tyre + Wheel Relationship
This FL5 is running:
- 18x10 +40 wheels
- 265 tyres (AD09)
Wider tyres increase grip but also:
👉 amplify alignment sensitivity
Without Proper Alignment
- tyre wears unevenly
- grip is inconsistent
- steering feels off
With Proper Alignment
- full tyre contact
- consistent grip
- predictable handling
Real-World Result
After alignment:
- steering is more precise
- car tracks straight
- cornering grip improves
- tyre wear becomes more even
Why Alignment Is Critical for Performance Builds
For setups like FL5 with wider wheels:
👉 alignment is not optional
It is part of the build.

Final Thoughts
Alignment numbers are not just data.
They directly affect:
- how the car feels
- how it grips
- how long tyres last
Understanding these numbers helps you get the most out of your setup.
FAQ
What is camber?
Camber is the tilt of the wheel, affecting cornering grip.
What is toe?
Toe controls stability and tyre wear.
What is caster?
Caster affects steering feel and return.
Why is alignment important?
It ensures tyres and suspension work correctly.
Does wider wheel need different alignment?
Yes, wider setups require more precise alignment.
How often should I check alignment?
After wheel changes or if tyre wear is uneven.
