Why This Wheel Spec Works on IS F

The 18x9.5 +45 setup provides:

• balanced stance without excessive poke
• correct clearance for brakes
• compatibility with wider tyre setup
• stable geometry for performance driving

👉 This is a controlled fitment, not an aggressive one

Why 265 Tyres Make a Difference

Compared to narrower setups, 265 width tyres:

• increase contact patch
• improve traction under acceleration
• provide better cornering stability

On a V8 rear-wheel-drive car like IS F, this is especially noticeable.

Why Michelin PS5 is Used

Michelin Pilot Sport 5 is chosen for:

• strong wet and dry grip
• consistent performance
• daily drivability
• longer lifespan than track tyres

👉 Ideal for a car that is driven regularly, not just occasionally

Wheel Alignment – The Most Important Step

After fitting wheels and tyres, a full alignment was performed.

From the report:

Rear Toe (Before)

• Left: 3.2 mm
• Right: 2.0 mm
• Total: 5.2 mm

👉 Excessive rear toe-in

Rear Toe (After)

• Left: 2.2 mm
• Right: 2.0 mm
• Total: 4.2 mm

👉 Brought closer to usable range

Front Toe Adjustment

Before

• Left: 2.6 mm
• Right: -1.3 mm

👉 Imbalance affecting steering

After

• Left: -0.1 mm
• Right: 0.0 mm

👉 Balanced and corrected

Camber Results

Front camber after alignment:

• Left: -1°24′
• Right: -1°01′

Rear camber:

• around factory range

👉 Balanced for both grip and tyre life

Real Driving Difference

After alignment:

• steering becomes more precise
• car tracks straight
• rear stability improves
• tyre wear becomes more even

Why Alignment Matters on IS F

The IS F is:

• rear-wheel drive
• high power
• sensitive to rear geometry

Incorrect alignment can cause:

• instability under acceleration
• uneven tyre wear
• unpredictable handling

Wheel + Tyre + Alignment Must Match

This setup works because:

• wheel spec is correct
• tyre size is matched
• alignment is adjusted

👉 All three are required for proper performance
