Parts for your 2009 Subaru Impreza-Coil springs

2009 Subaru Impreza Coil Springs

Based on technical references including the Subaru workshop manual for GE/GH/GR models (MY2008–2011) and OEM parts catalogues from Subaru and major suspension manufacturers, the 2009 Subaru Impreza is fitted with coil springs front and rear. The front uses a MacPherson strut with a coil spring over the damper, while the rear runs a multi‑link/double‑wishbone layout with separate coil springs paired to shocks.

On a 2009 Impreza, coil springs carry the vehicle’s weight, set the ride height, and control how the car responds to bumps and cornering. They work with the struts/shocks to keep the tyres planted, which helps braking stability and steering feel. Worn or sagging springs can make the hatch or sedan sit unevenly, reduce ground clearance, and throw out alignment, which leads to odd tyre wear and a harsher or bouncier ride.

For everyday servicing, a quick look at the coil springs is worth adding to the checklist every 10,000–20,000 km or annually. Surface rust is common with age, but flaking, cracked paint, deep corrosion pits, a broken pigtail end, or shiny coils from coil-bind are red flags. If one spring is gone soft, the other on the same axle won’t be far behind, so replace in axle pairs. After spring or strut work, a wheel alignment is strongly recommended.

• Typical symptoms: nose‑down stance, sagging rear, clunks over bumps, excessive bounce, steering pull, or uneven tyre wear.
• Good practice: fit new upper mounts/insulators and bump stops with springs and struts, torque everything at normal ride height.
• Parts matching: spring rates differ between 2.0/2.5 models, WRX/STI, sedan vs hatch. Use VIN/option codes to get the right rate and height.
• Safety first: coil springs are under serious tension. Use a quality spring compressor or have a pro handle the job.

For Aussie and Kiwi drivers who tackle gravel, towing, or full loads, consider OE‑equivalent or slightly uprated springs to keep the Impreza level. Keep the coils clean, rinse off road grime, and touch up chipped coating to slow corrosion. If lowering or lifting, check local compliance (e.g., WOF in NZ and state regs in AU) to stay road‑legal and insured.

Popular questions about 2009 Subaru Impreza coil springs

How long do 2009 Subaru Impreza coil springs last?

In typical AU/NZ conditions, factory coil springs often last 10–15 years or 150,000+ km. Coastal exposure, gravel roads, heavy loads, and lowered setups can shorten their life. If ride height is uneven or the ride feels crashy or floaty, inspect sooner rather than later.

Do you need a wheel alignment after replacing coil springs?

Yes. Any change to springs or struts alters ride height and geometry, which shifts camber and toe. A proper alignment helps protect tyres, restores steering feel, and keeps the Impreza tracking straight.

Can WRX or STI springs be used on a regular 2009 Impreza?

They’ll physically fit certain variants, but rates and free lengths differ. Mixing can upset ride height and damping unless matched with appropriate struts. Also consider AU/NZ compliance rules if the height changes beyond allowed limits. Best bet: choose springs specified for the exact trim and intended use.
