Parts for your 2006 Subaru Impreza-Coil springs

2006 Subaru Impreza coil-springs — what they do and when to replace them

Based on technical sources — the Subaru Factory Service Manual (via STIS), genuine Subaru parts catalogues for the GD/GG chassis, and mainstream workshop manuals covering 2002–2007 models — the 2006 Subaru Impreza runs MacPherson struts with coil-springs at the front and strut-type suspension with coil-springs at the rear. So coil-springs are absolutely relevant and fitted to this vehicle across non-turbo and WRX variants, with model-specific spring rates.

On a 2006 Impreza, coil-springs hold the car at the correct ride height, support weight, and keep the tyres planted over Aussie and Kiwi roads. Working with the struts, they absorb bumps, help stability in corners, and make sure the all-wheel-drive system can do its best. The right spring rate keeps things comfortable without turning the daily commute into a rally stage.

Springs aren’t a “replace by kilometres” item, but they do fatigue. As part of regular servicing, it’s smart to inspect them for rust, cracked coating, and broken ends, especially if the car sees rough roads or heavy loads. If the Impreza sits low at one corner, bottoms out over speed humps, or clunks on take-off, the springs may be tired.

• Check ride height side-to-side and front-to-rear against spec, uneven stance points to sagging springs.
• Listen for creaks or knocks over kerbs and speed bumps, inspect for chipped paint, corrosion, or fractured coils.
• Watch for odd tyre wear and wandering steering — worn springs can upset camber and toe.
• Replace springs in axle pairs and match them to the exact model (sedan vs wagon, WRX vs non-turbo).
• Have the strut top mounts, bearings, isolators, and bump stops checked or renewed at the same time.
• Torque suspension bolts at normal ride height and book a wheel alignment straight after.

DIYers should use a quality spring compressor and proper safety gear, these coils store serious energy. Many owners refresh the struts together with springs to restore ride and handling. Considering a lower or firmer setup? Make sure the spring choice suits your dampers and complies with local certification rules (e.g., WOF in NZ or state regs for roadworthy checks in Australia). Done right, fresh coil-springs bring back that tidy, confident Impreza feel without beating up the daily drive.

Popular questions

How long do coil-springs last on a 2006 Impreza?
With normal driving, many see 150,000–250,000 kilometres before noticeable sag or breakage, but coastal corrosion, gravel roads, and heavy loads can shorten that. Inspect at each service and act on any ride-height drop or noise.

Do coil-springs need replacing when I change struts?
Not always, but it’s common to do both if the car has high kilometres or the ride height has sunk. It’s efficient to fit new top mounts and isolators at the same time, then finish with an alignment.

Which coil-springs fit my specific 2006 Impreza?
Fitment depends on body (sedan GD vs wagon GG), engine/trim (WRX vs non-turbo), and market. Use the VIN and any spring paint codes to match the right rate and height, and always replace in pairs per axle.
