Bmw 320I Coil Spring Shims

Bmw 320I Coil spring shims

Coil spring shims for your Bmw 320I start at $48.95, with 1 options from URO. A coil spring shim is a thin wedge or spacer inserted between the coil spring and its seat to correct ride height, adjust corner weight, and eliminate metallic clunking. When shims shift, crack, or go missing, handling becomes uneven and tire wear accelerates.

Signs your Bmw 320I needs new coil spring shims

  • One corner of the vehicle sits noticeably lower than the others, even after confirming the spring itself is intact
  • Metallic clunking or ticking from a corner of the suspension when going over bumps or turning at low speed
  • Uneven or accelerated tire wear on one side, particularly feathering or camber-related edge wear
  • Steering pulls consistently to one side on a flat, level road without brake application
  • Visible gap, cocking, or lateral shift of the coil spring on its lower or upper seat
  • Ride height measurement at one corner is outside the manufacturer's specified range after spring and strut inspection

Which coil spring shim should you buy for your Bmw 320I?

The right shim depends on where the correction is needed — upper seat, lower seat, or both — and how much ride height or angle adjustment is required. Material and construction also matter: rubber-bonded shims absorb vibration better, while solid steel or aluminum shims offer more precise, permanent correction. Match shim thickness and taper angle to your measured ride height deficit.

Rubber-bonded shim
Best for
Eliminating spring seat noise and minor height correction
What you get
Noise isolation plus a small, consistent lift; easiest to install and least likely to migrate
Solid steel tapered shim
Best for
Permanent camber or caster correction at the spring seat
What you get
Precise angle correction measured in degrees; no compression over time, ideal for alignment-critical applications
Polyurethane shim/spacer
Best for
Moderate ride height restoration on worn springs
What you get
Firmer than rubber, resists oil and road debris, adds measurable lift without replacing the spring
Aluminum billet shim plate
Best for
Performance or track applications needing exact corner-weight tuning
What you get
Lightweight, corrosion-resistant, and machineable to exact thickness; best where fine tuning matters more than noise absorption

Replacing coil spring shims on a Bmw 320I

On strut-style front suspension, the strut assembly must be removed and the spring compressed before the upper mount can be separated and the shim inserted or swapped at the spring seat — never attempt this without proper spring compressor tools. Rear leaf-over-coil or separate spring setups are more accessible and often allow shim placement with the spring partially unloaded on a jack. After reassembly, torque all suspension fasteners to specification with the vehicle at ride height, then have the alignment verified before returning to normal driving.

Frequently asked questions

How much does it cost to replace coil spring shims on a Bmw 320I?
Coil spring shims for a Bmw 320I start at $48.95 for the parts. DIY installation adds only basic tool costs. A shop will typically bundle this with a spring or strut job, so labor varies widely. Budget for a four-wheel alignment after any spring seat work, as ride height changes affect camber and toe.
Can I drive my Bmw 320I with a missing or broken coil spring shim?
You can drive short distances, but it is not advisable. A missing shim allows the spring to sit off-center or at the wrong angle, placing uneven stress on the strut shaft and bearing plate. Over time this accelerates tire wear, can damage the spring itself, and may cause the spring to shift abruptly during cornering.
Will adding a coil spring shim on my Bmw 320I affect wheel alignment?
Yes, any change to spring seat height or angle directly affects camber and, to a lesser extent, caster. Even a few millimeters of ride height change can push camber outside specification. Always schedule a four-wheel alignment immediately after installing coil spring shims to prevent premature tire wear and restore proper handling.
How do I know what thickness coil spring shim my Bmw 320I needs?
Measure actual ride height at each corner with the vehicle on a level surface and compare it to the factory specification in your service manual. The difference between measured and specified height, adjusted for spring rate, determines shim thickness. For angle correction, a before-and-after alignment printout showing camber deviation is the most reliable guide.
Are coil spring shims a permanent fix or a temporary repair?
Quality steel or aluminum shims are a permanent correction and are used by OEM manufacturers and professional alignment shops. Rubber and polyurethane shims can compress slightly over time, especially under heavy load, so periodic recheck is wise. They are not a substitute for a spring that is broken or has lost significant free length.
Do coil spring shims work on both front and rear suspension of a Bmw 320I?
Yes. Shims are used at both ends wherever a coil spring seats against a fixed perch or strut mount. Rear applications are common for correcting sag from years of load-carrying. Front applications more often address camber correction. Confirm whether your Bmw 320I uses a strut-style or separate spring-and-shock layout before ordering, as seat geometry differs.
