Nissan Note E12 is a compact hatchback that is valued for its efficiency and maneuverability, but its factory ground clearance (155–160 mm) often becomes a headache for owners operating the car on Russian roads. Uneven surfaces, curbs and snow drifts in winter make you think about increasing the ground clearance. One of the most accessible ways is to install spacers for springs or struts.
In this article we will look at all the nuances: from the choice of materials (polyurethane, aluminum, steel) to step-by-step installation instructions. We will pay special attention critical installation errors that lead to accelerated wear of the suspension and loss of controllability. We will also analyze how spacers affect the life of shock absorbers, wheel alignment angles and the behavior of the car at high speeds.
Why increase ground clearance? Nissan Note E12?
Standard ground clearance Note E12 (155 mm front and 160 mm rear) designed for European roads with smooth asphalt. In the realities of Russian regions, this is often not enough. Here are the main reasons why owners resort to spacers:
- 🚗 Winter operation: Snow drifts and hard ruts require an additional 20–30 mm of ground clearance to avoid getting stuck.
- 💥 Potholes and unevenness: Even a small increase in clearance reduces the risk of damage to the crankcase guard or front bumper.
- 🏞️ Traveling on dirt roads: For summer residents and travelers, spacers are becoming a mandatory upgrade.
- 🔧 Installation of non-standard wheels: If you have larger diameter wheels or tires, spacers will help prevent friction on the fender liners.
However, it is important to understand that increasing ground clearance is always a compromise. For example, the machine's center of gravity rises, which may impair cornering stability and increase body roll. The suspension angles also change, which leads to uneven tire wear.
⚠️ Attention: Spacers with a thickness of more than 30 mm require the mandatory replacement of shock absorbers with reinforced or adjustable ones. Otherwise, the service life of the racks is reduced by 30–40%.
Types of spacers: which ones are suitable for Nissan Note E12?
Spacers are divided into two main types depending on the installation location:
- Under springs (between the coils and the shock absorber cup) is the most common option. Easy to install, but require disassembly of the rack.
- Under racks (between the support bearing and the body) - they change the suspension geometry more, but avoid disassembling the shock absorber.
According to the material of manufacture:
| Material | Pros | Cons | Service life |
|---|---|---|---|
| Polyurethane | Lightweight, does not rust, absorbs vibrations | Deforms under load, afraid of high temperatures | 3–5 years |
| Aluminum | Rigid, non-deformable, corrosion resistant | Dear, transmits vibrations to the body | 10+ years |
| Steel | Durable, cheap, withstands high loads | Rustes, increases suspension weight | 7–10 years |
| Composite | Lightweight, does not rust, dampens noise | Dear, it's hard to find for Note E12 | 5–8 years |
For Nissan Note E12 are considered the optimal choice polyurethane spacers 20–25 mm thick under the springs. They do not require suspension modifications and dampen vibrations well. Aluminum options are suitable for aggressive driving, but their installation will cost more.

Spacer thickness: how many millimeters is enough?
The choice of thickness depends on the goals:
- 🔹 15–20 mm: Minimum increase for winter use. Almost no effect on handling.
- 🔹 25–30 mm: a universal option for primers and urban conditions. Requires camber adjustment.
- 🔹 35–40 mm: for serious off-road use. Replacement of shock absorbers and steering rods is required.
On Note E12 spacers thicker than 30 mm leads to:
- 🔧 Changing angles
casterAndcamber, which leads to accelerated tire wear. - 🚘 Increased body roll when cornering (risk of rollover at speeds over 100 km/h).
- 💡 The need to extend brake hoses and parking brake cables.
⚠️ Attention: Spacers 40+ mm thick on Note E12 require certification by the traffic police as a design change. Without this, the car will not pass inspection.
The optimal balance for most owners is 20–25 mm. This gives +2 cm of ground clearance without critical consequences for the suspension. With this thickness it is enough to do wheel alignment and check the condition of the silent blocks.
If you plan to install spacers thicker than 25 mm, buy extended bolts for securing the struts in advance - standard ones may not be enough.
Step-by-step instructions for installing spacers
You can do the installation yourself if you have experience working with suspension. You will need:
- 🔧 Jack and stops (or lift).
- 🔨 Set of sockets and keys (10, 12, 14, 17 mm).
- 🧲 Ties for springs (if spacers are for springs).
- 🛠️ Torque wrench (for proper tightening).
Procedure for spring spacers:
☑️ Preparation for installation
Remove the shock absorber strut, first disconnecting the brake caliper and ball joint. Use spring ties to avoid injury.
Disassemble the strut: remove the support bearing, spring and boot. Clean the shock absorber cup from dirt.
Install a spacer between the spring and the cup. For polyurethane models, use a special fixing adhesive.
Reassemble the stand in reverse order. Tighten the nuts with a torque wrench
50–60 Nm.Place the strut in place, connect the caliper and ball joint. Repeat for the second wheel.
For spacers under the struts, the process is simpler: just unscrew the three bolts securing the support bearing to the body, insert the spacer and tighten the bolts. However, this method greatly changes the suspension geometry.
What should I do if there is a knocking noise after installation?
The knocking noise may occur due to improper tightening of the bolts or deformation of the polyurethane spacer. Check:
1. Tighten all fasteners (especially the upper support).
2. Condition of the support bearing - it may jam.
3. Integrity of the spacer (cracks, chips).
If the knocking noise persists, replace the spacer with an aluminum or steel one.
Consequences of the installation: what will change in the behavior of the car?
Even a small increase in ground clearance affects the car's performance. Here's what to expect:
✅ Pros:
- 🚙 More confidence on rough roads and snow.
- 🛡️ Bumper and crankcase protection from impacts.
- 🔄 Possibility of installing wheels of larger diameter (for example,
R16instead ofR15).
❌ Cons:
- 🌀 Increased body roll when cornering (especially noticeable at speeds > 80 km/h).
- 🔧 Faster wear of silent blocks and ball joints.
- 📉 Reduced steering accuracy (due to changes in suspension angles).
- 💨 Deterioration in aerodynamics and increase in fuel consumption by 0.3–0.5 l/100 km.
To minimize negative effects:
- 🔧 Do it wheel alignment after installation (required!).
- 🛠️ Check the condition of the shock absorbers every 10,000 km.
- 🚗 Avoid sudden maneuvers at high speed.
Spacers up to 20 mm thick on Nissan Note E12 do not require modifications to the brake system or steering rods. But at 25+ mm, be sure to check the length of the brake hoses!
Review of popular brands of spacers for Note E12
There are spacers from dozens of manufacturers on the market, but not all are suitable for Nissan Note E12. We tested several options:
| Brand | Material | Thickness (mm) | Price (per set) | Features |

| Febi | Aluminum | 15, 20, 30 | 4 500–6 000 ₽ | Precise geometry, anodized finish |
| Topran | Steel | 25, 30 | 2 800–3 500 ₽ | Budget option, requires anticorrosive treatment |
| Meyle | Composite | 20 | 5 500 ₽ | The lightest and most durable, but expensive |
For most owners Note E12 spacers would be the best choice KYB (polyurethane, 20 mm) or Febi (aluminum, 25 mm). The former are cheaper and quieter, the latter are more reliable for aggressive driving. Steel spacers Topran suitable for those who are looking for a budget solution and are ready for additional anti-corrosion treatment.
When purchasing, pay attention to:
- 📏 Exact dimensions (must match the diameter of the shock absorber cup Note E12 —
120 mm). - 🔩 Extended bolts included (if not, buy separately).
- 📄 Certificate of conformity (especially for spacers thicker than 30 mm).
Common installation mistakes and how to avoid them
Improper installation of spacers can lead to serious problems: from squeaks to suspension failure. Here are the most common mistakes:
Using spacers without spring clamps. This is dangerous - the spring may “shoot” when disassembling the strut.
Insufficient bolt tightening. Leads to play and knocking. Always use a torque wrench!
Installing spacers on one axle only. This upsets the balance of the car and impairs handling.
Ignoring wheel alignment. Even 20mm spacers change angles, leading to uneven tire wear.
Buying cheap spacers without a certificate. They may become warped or cracked after a few months.
To avoid problems:
- 🔧 Before installation, check the condition of shock absorbers and silent blocks. If they are worn out, spacers will only speed up their failure.
- 📐 After installation, measure the ground clearance on each side - the difference should not exceed 5 mm.
- 🚗 Drive carefully for the first 100 km, avoiding sudden braking and turning.
⚠️ Attention: If after installing the spacers the car “floats” on the road or the steering wheel becomes stiff, immediately check the wheel alignment angles. This is a sign of a critical change in suspension geometry!
FAQ: Answers to frequently asked questions
❓ Is it necessary to do camber after installing 20 mm spacers?
✅ Yes, definitely. Even a small change in ground clearance affects the camber and toe angles. Without alignment, your tires will wear unevenly (especially on the inside).
❓ Is it possible to install spacers only on the front axle?
❌ Not recommended. This will upset the balance of the car: the front end will become higher, which will worsen handling and increase the risk of capsizing when cornering. Install spacers of equal thickness on both axles.
❓ How do spacers affect the life of shock absorbers?
🔧 Spacers increase the load on shock absorbers, especially with a thickness of 25+ mm. On average, the service life of racks is reduced by:
- 10–15% with 20 mm spacers;
- 25–30% at 25–30 mm;
- 40%+ for 35mm and thicker.
If your shock absorbers have already worked > 80,000 km, it is better to replace them with reinforced ones (for example, Kayaba Excel-G) before installing spacers.
❓ Is it possible to pass a technical inspection with spacers?
✅ Yes, if thickness is up to 30 mm. Spacers are not considered a design change as long as they are certified and within reasonable limits. However, the inspector may require:
- Show certificate for spacers;
- Check the functionality of the steering and brakes;
- Make sure that the headlights do not blind oncoming drivers (a raised vehicle may require adjustment of the lights).
Spacers thicker than 30 mm require changes to the title.
❓ Spacers squeak after installation - what to do?
🔊 Creaking usually occurs due to:
- Polyurethane spacers - treat them with silicone grease or a special spray for plastic;
- Metal spacers — check the tightness of the bolts and add rubber gaskets;
- Worn support bearing - replace it.
If the squeaking continues, replace the spacers with aluminum or steel ones.
