Modified car and VTV: adjustable suspension in Argentina
This article is currently available in Spanish. A native English version is coming soon. Quick summary: the official 2026 procedures manual of the Buenos Aires province vehicle inspection (VTV) does not provide a way to "homologate" an adjustable suspension kit by itself. What it asks for is a signed technical report on your car from a registered mechanical engineer (Colegio de Ingenieros de la Provincia de Buenos Aires or COPIME). The same manual forbids cut springs and modified shock absorber mounts, and leaves it to the inspection station's technical head to decide whether the report is enough.
The Spanish article also covers what national traffic law (Ley 24.449 and Decreto 779/95) says about modifying the suspension, the rules in the City of Buenos Aires, and what an inspection station checks on wheels and tyres. It is a guide, not legal advice: ask your inspection station before you modify anything. Read the full Spanish version of this article.
