Good to know before booking

Does lowering require a modification inspection?

It depends on the vehicle and modification. Send the registration number and details of the springs or suspension kit before installation so the inspector can assess the requirements.

Can I check the requirements before buying parts?

Yes. Tell us the intended modification and planned components. Checking in advance helps you obtain the correct certificates.

Why does the price start at €63?

Modifications range from one simple inspection to reviewing several structures and certificates. The final price depends on the scope of work.
