VK & VL Commodore Lowering Guide

Clicking a link to eBay [or other affiliations] may result in a referral commission being paid if a purchase is made.

Lowering a VK or VL Commodore is one of the most popular modifications among Holden enthusiasts. It improves stance, handling, and road presence, transforming the classic 1980s Commodore into a more aggressive and better-handling vehicle.

However, because VK (1984–1986) and VL (1986–1988) Commodores are now over 35 years old, lowering them requires careful planning. Suspension wear, bush deterioration, and outdated geometry all need to be considered before modifying ride height.

Why Lower a VK or VL Commodore?

Lowering is done for both performance and appearance.

Benefits

  • Reduced body roll
  • Improved cornering stability
  • Lower centre of gravity
  • Better road stance
  • Enhanced handling feel

When done correctly, lowering improves driving dynamics significantly.

VK vs VL Lowering Considerations

VK Commodore

  • Simpler suspension setup
  • More forgiving geometry
  • Responds well to moderate lowering

VL Commodore

  • More refined suspension tuning
  • Slightly more sensitive to alignment changes
  • Turbo models benefit from conservative lowering

Both models respond best to balanced, moderate setups rather than extreme lowering.

Best Ways to Lower a VK or VL Commodore

There are several methods available, each with different benefits.

1. Lowering Springs (Most Common Option)

Lowering springs are the most popular choice for street-driven Commodores.

Benefits

  • Affordable
  • Easy to install
  • Maintains factory shock geometry (in mild setups)
  • Improved handling

Recommended Brands

  • King Springs
  • Lovells Springs

Typical Lowering Heights

  • Mild: 20–30mm (daily driving comfort)
  • Moderate: 30–50mm (best balance)
  • Low: 50mm+ (show car stance, reduced comfort)

2. Coilover Suspension Kits

Coilovers offer full adjustability for height and sometimes damping.

Benefits

  • Adjustable ride height
  • Improved handling precision
  • Tunable performance setup

Trade-Offs

  • Higher cost
  • Firmer ride
  • More maintenance required

Best For

  • Performance builds
  • VL Turbo enthusiasts
  • Track-oriented setups

3. Shock Absorber Matching

Lowering must be matched with appropriate shocks.

Recommended Options

  • Monroe GT Gas (budget-friendly)
  • KYB Excel-G (balanced performance)
  • Bilstein (premium performance)

Why It Matters

Incorrect shocks can cause:

  • Bottoming out
  • Poor handling
  • Premature suspension wear

4. Polyurethane Bush Upgrade

Lowering increases stress on suspension bushes.

Benefits

  • Improved steering response
  • Longer lifespan than rubber
  • Reduced suspension flex

Common Areas

  • Control arms
  • Sway bar mounts
  • Panhard rod bushes

5. Adjustable Panhard Rod

Essential for rear axle alignment after lowering.

Benefits

  • Keeps rear axle centred
  • Improves stability
  • Prevents uneven tyre wear

Why It’s Important

Lowering shifts the rear axle sideways due to suspension geometry changes.

6. Wheel Alignment After Lowering

Proper alignment is critical after any suspension change.

What to Check

  • Camber
  • Toe settings
  • Rear axle position

Symptoms of Poor Alignment

  • Uneven tyre wear
  • Pulling to one side
  • Unstable handling

7. Sway Bar Upgrades (Recommended)

Sway bars improve cornering stability.

Benefits

  • Reduced body roll
  • Better corner balance
  • Improved handling response

Upgrade Options

  • Thicker front sway bar
  • Upgraded rear sway bar
  • Heavy-duty sway bar links

Common Lowering Mistakes

1. Lowering Too Much

Excessive lowering causes:

  • Bottoming out
  • Poor ride quality
  • Reduced suspension travel

2. Not Upgrading Shocks

Stock shocks cannot cope with lowered springs effectively.

3. Ignoring Panhard Rod Adjustment

Leads to rear-end instability and uneven tyre wear.

4. Poor Quality Springs

Cheap springs may sag or lose performance quickly.

Ride Quality vs Performance Balance

Comfort Setup

  • Mild lowering (20–30mm)
  • Quality shocks
  • Standard bushes

Balanced Street Setup

  • Moderate lowering (30–50mm)
  • Upgraded shocks
  • Polyurethane bushes
  • Adjustable panhard rod

Performance Setup

  • Coilovers
  • Heavy-duty sway bars
  • Full bush replacement
  • Adjustable geometry components

VK vs VL Lowering Results

VK Commodore

  • More forgiving ride quality
  • Responds well to basic lowering kits

VL Commodore

  • More sensitive to alignment and setup
  • Benefits from careful tuning and quality components

Both gain significant improvement when properly set up.

Signs Your Suspension Needs Attention Before Lowering

  • Clunking noises
  • Uneven tyre wear
  • Excessive bounce
  • Loose steering feel
  • Sagging ride height

All worn components should be replaced before lowering.

Best Lowering Upgrade Packages

Budget Setup

  • King Springs
  • Monroe GT shocks
  • Standard replacement bushes

Street Performance Setup

  • King Springs or Lovells
  • KYB or Bilstein shocks
  • Polyurethane bush kit
  • Adjustable panhard rod

Full Performance Setup

  • Coilovers
  • Heavy-duty sway bars
  • Full polyurethane bush replacement
  • Adjustable rear geometry components

Lowering a VK or VL Commodore can dramatically improve both appearance and handling when done correctly. However, because these vehicles are now decades old, suspension condition and component quality are just as important as ride height.

The key is balance—moderate lowering combined with quality shocks, fresh bushes, and proper alignment delivers the best real-world results.

When properly set up, a lowered VK or VL Commodore becomes more stable, more responsive, and far more enjoyable to drive while still retaining classic Holden character.
