Lowering a VT or VX Commodore is one of the most popular modifications among Holden enthusiasts. A properly lowered Commodore not only improves the vehicle’s appearance but can also enhance handling, reduce body roll, and provide a more aggressive stance.
Thanks to the VT and VX platform’s independent rear suspension (IRS) design and modern suspension geometry, these vehicles respond very well to lowering when done correctly. However, choosing the right springs, shocks, and ride height is essential to avoid poor ride quality, tyre wear, and handling issues.
Why Lower a VT or VX Commodore?
Lowering offers both cosmetic and performance benefits.
Advantages
- Improved appearance
- Reduced wheel gap
- Lower centre of gravity
- Improved cornering stability
- Reduced body roll
- Better road presence
Many owners consider lowering one of the most effective modifications available.
Understanding Factory Ride Height
Factory VT and VX Commodores were designed to provide a balance of:
- Comfort
- Ground clearance
- Load carrying ability
- Handling
As a result, many owners feel the standard ride height appears too high.
Common Lowering Heights
Low
Approximate Drop
- 25–30mm
Benefits
- Improved appearance
- Maintains ride quality
- Minimal clearance issues
Best For
- Daily drivers
- Touring vehicles
This is often considered the ideal compromise.
Super Low
Approximate Drop
- 40–50mm
Benefits
- Aggressive stance
- Improved handling
Considerations
- Reduced ground clearance
- Increased risk of scraping
Best For
- Street cars
- Weekend vehicles
One of the most popular options for Commodore owners.
Ultra Low
Approximate Drop
- 60mm or more
Benefits
- Maximum visual impact
Drawbacks
- Reduced suspension travel
- Ride quality deterioration
- Clearance problems
Best For
- Show vehicles
Not ideal for everyday driving.
Lowering Springs
The most common lowering method.
Benefits
- Affordable
- Reliable
- Simple installation
Available Heights
- Low
- Super Low
- Ultra Low
Quality springs are essential for proper handling.
Matching Shock Absorbers
One of the biggest mistakes owners make is lowering a vehicle without upgrading the shocks.
Why It Matters
Lowered springs reduce suspension travel.
Benefits of Matching Shocks
- Better ride control
- Reduced bouncing
- Improved handling
- Longer suspension life
Performance shocks are strongly recommended.
Best Suspension Combination
For most VT and VX owners:
Recommended Setup
- Low or Super Low springs
- Quality performance shocks
- Wheel alignment
This delivers the best balance of comfort and performance.
Independent Rear Suspension Considerations
The VT and VX IRS setup responds well to lowering.
However:
Possible Issues
- Increased negative camber
- Inner tyre wear
- Alignment changes
Professional alignment is essential after lowering.
Wheel Alignment After Lowering
A wheel alignment should always be performed after suspension modifications.
Benefits
- Improved tyre life
- Better handling
- Reduced steering issues
Skipping alignment often results in uneven tyre wear.
Camber Changes
Lowering naturally increases negative camber.
Benefits
- Improved cornering grip
Drawbacks
- Accelerated inner tyre wear
Moderate lowering generally causes manageable camber changes.
Sway Bar Upgrades
Many owners combine lowering with sway bar upgrades.
Benefits
- Reduced body roll
- Sharper handling
- Improved stability
This is one of the best handling upgrades available.
Common Lowering Problems
Tyre Wear
Usually caused by incorrect alignment.
Scraping
More common with Super Low and Ultra Low setups.
Common Areas
- Front bumper
- Exhaust system
- Crossmember
Reduced Ride Quality
Can occur when:
- Springs are too low
- Factory shocks are retained
Bottoming Out
Usually caused by insufficient suspension travel.
Best Lowering Setup for Daily Drivers
Recommended
- Low springs
- Quality shocks
- Standard wheel sizes
Provides excellent comfort and handling.
Best Lowering Setup for Street Performance
Recommended

Recommended
- Performance springs
- Heavy-duty shocks
- Alignment optimisation
