Parts for your 2016 Subaru Impreza-Coil springs

2016 Subaru Impreza Coil Springs — Purpose, Care, and When to Replace

Per technical references including the Subaru Factory Service Manual (2012–2016 Impreza, GP/GJ chassis), the Subaru Genuine Parts Catalogue, and the owner’s handbook, the 2016 Impreza runs MacPherson struts with coil springs up front and a rear double‑wishbone set‑up with coil springs. So coil springs are absolutely relevant and fitted to this model.

On the 2016 Subaru Impreza, the coil springs carry the vehicle’s weight, set ride height, and keep the tyres planted over bumps. Working with the struts/shocks, they absorb road impacts and help the car steer and brake predictably. If they sag or crack, handling suffers, ride gets harsh, and tyres can wear unevenly.

There’s no fixed replacement interval for coil springs, but regular inspection is smart. For Aussie and Kiwi conditions—think coastal air, corrugations, and the odd gravel road—checking them at each service is a good habit, especially once the odometer nudges past 80,000–120,000 km or if the car frequently carries loads.

• What to look for: uneven ride height, clunks over bumps, excessive bounce, scraping under load, cracked paint with rust, or a broken coil end (pigtail).
• Good practice: wash the underbody after beach or rural drives, keep spring seats free of mud and debris, and listen for new noises over speedhumps.

When replacement’s due, it’s best to do them in axle pairs (both fronts or both rears) to keep handling even. Choose springs that match the intended ride height—OE‑equivalent for stock feel, or a properly engineered raised/lowered option if changing stance. Avoid heating or cutting springs. A quality internal or external spring compressor is essential, if that sounds dicey, leave it to a workshop.

Complementary parts worth doing at the same time include strut mounts/bearings, insulators, bump stops, and dust boots. After any spring change, a four‑wheel alignment is a must to protect tyre wear and restore crisp steering. Torque all suspension bushings at normal ride height to prevent pre‑load and squeaks.

In NZ, damaged or significantly sagged springs can see a WOF failure, in Australia, expect similar issues at a roadworthy check. Keeping the Impreza’s coil springs healthy means safer cornering, smoother commutes, and tyres that last the distance.

Popular questions about 2016 Subaru Impreza coil springs

How long do the factory coil springs last?
There isn’t a set lifespan, but many Imprezas see well over 150,000 km on original springs if not overloaded or corroded. Coastal exposure, repeated heavy loads, and rough roads can shorten that, so inspect them at every service and act on any sag, cracks, or rust.

Do I need a wheel alignment after replacing coil springs?
Yes. Changing springs alters ride height and can shift camber, caster, and toe. A proper alignment right after installation helps the Impreza track straight and prevents premature tyre wear.

Can I replace just one coil spring?
It’s strongly recommended to replace springs in pairs on the same axle. Mixing an old and a new spring can leave the car sitting unevenly and affect handling balance and braking stability.
