Short answer: The three most common installation errors with KW coilover suspensions: (1) Tightening rubber bushing bolts when the suspension is unloaded – this twists the suspension and ruins the bushings. (2) Adjusting too low below KW’s minimum height – this ruins geometry and drive shafts. (3) No wheel alignment after installation – results in uneven tire wear. Always tighten bolts with the vehicle on its wheels and at the correct torque.
A KW coilover suspension not only offers a sportier look but also a significant improvement in driving dynamics. However, installation is a demanding task, and mistakes are frequently made. These can not only reduce performance but, in the worst case, also lead to suspension problems or excessive wear. Here, we show you what you need to pay attention to during installation and which mistakes you absolutely must avoid. 🚀
❌ Typical Errors When Installing a KW Coilover Suspension
1️⃣ Tightening Rubber Bushings When Unloaded
One of the most common installation errors is tightening the suspension bushings when the suspension is unloaded. This leads to stress in the suspension, which degrades comfort and causes premature wear of the rubber bushings. Tip: Always lower the vehicle onto its wheels first and then tighten the bolts to the correct torque.
2️⃣ Incorrect Height Adjustment of the Coilover
Many drivers tend to set the suspension too low without considering KW's recommended minimum values. Setting it too low can:
✔ Negatively affect suspension geometry
✔ Shorten suspension travel too much, leading to poor handling
✔ Overload the drive shafts
Tip: Observe the manufacturer's specifications for minimum and maximum height and check the height again after the suspension has settled.
3️⃣ Wheel Alignment Not Performed After Installation
A coilover suspension changes the axle geometry. If the vehicle is not professionally aligned after installation, this can lead to:
✔ Uneven tire wear
✔ Unstable handling
✔ Suboptimal performance
Tip: ALWAYS have a wheel alignment performed after installation.
4️⃣ Top Mounts or End Links Not Adapted
Some KW suspensions are compatible with adjustable top mounts or end links. If these are incorrectly mounted or not adjusted, it can lead to noises or imprecise steering behavior.
Tip: Check that adjustable components are correctly aligned.
5️⃣ Incorrect Tightening Torque for Bolts
Many forget to tighten the fastenings to the correct torque. Too loose → risk of parts coming loose. Too tight → damage to components.
Tip: Use the torque values from the KW installation instructions.
✅ Important Points for Successful Installation
✔ Don't set the suspension too low immediately; gradually work your way down
✔ Have a wheel alignment performed to avoid tire wear & poor handling
✔ Tighten bolts with torque when loaded to prevent stress
✔ Check end links & top mounts to avoid rattling noises
✔ Recheck suspension components after a few hundred kilometers, as the suspension may settle
