Parts for your 2007 Subaru Impreza-Coil springs

2007 Subaru Impreza coil springs — purpose, care and when to replace

Coil springs are definitely fitted to the 2007 Subaru Impreza range. Technical references including the Subaru Factory Service Manual for MY2007 (Suspension section), Subaru’s technical information system, and major damper catalogues (KYB/Monroe) all describe a MacPherson strut front and strut-type rear suspension, each using helical coil springs across Impreza, WRX and STI variants. So yes, coil springs are relevant, front and rear.

On a 2007 Impreza, the coil springs carry the vehicle’s weight, set the ride height, and work with the struts to soak up bumps and keep the tyres in contact with the road. They’re a big part of how the car corners, brakes and rides. Different trims run different spring rates and heights, so WRX/STI springs aren’t the same as standard Impreza items.

While coil springs aren’t a scheduled replacement item, they do wear and can break, especially with Aussie and Kiwi roads, beachside corrosion, and heavier loads. During regular servicing, it’s smart to have a quick check.

• Watch for sagging ride height, the car leaning to one side, or bouncy, boaty behaviour.
• Listen for clunks over bumps, inspect for cracked paint, rust pitting, or a snapped coil tail.
• Uneven tyre wear and vague steering can also point to tired springs or struts.

If replacement’s needed, do both sides on the same axle so handling stays even. Match springs to your exact model (sedan vs wagon, WRX/STI vs non-turbo) using VIN or OEM part numbers. Pairing new springs with fresh struts/top mounts often restores the Impreza’s sharp feel. After any spring work, get a wheel alignment.

• Use a proper spring compressor — stored energy in a coil is no joke. If unsure, leave it to a pro.
• Replace associated bits: top mounts, insulators, dust boots and bump stops.
• Torque suspension fasteners at normal ride height to protect bushes.

For NZ WOF or Aussie rego inspections, a broken or sagged spring is a fail. With our mix of potholes, corrugations and coastal air, a periodic look-over pays off. Keep them healthy and the Impreza keeps its tidy, confidence-inspiring road manners.

Popular questions

Does a 2007 Subaru Impreza have coil springs front and rear?
Yes. Technical manuals for MY2007 Impreza specify MacPherson struts with coil springs at the front and strut-type suspension with coil springs at the rear across the range, including WRX and STI.

How long do Impreza coil springs last, and when should they be replaced?
There’s no fixed kilometre interval. Replace if a spring is cracked, sagging, corroded to the point of weakness, or if ride height and handling are off. Many last well past 150,000 km, but coastal use and rough roads shorten life.

Can just one spring be replaced?
It’s best to replace springs in axle pairs. One new spring and one old can leave the car sitting unevenly and won’t feel right. Do both sides, then get an alignment.
