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.

Frequently asked questions

Can a car with adjustable suspension pass the VTV inspection?
The Buenos Aires province manual does not ban it by name, but it requires every change from the original to be certified by a registered mechanical engineer, shock absorbers to be commercial replacement parts and mounts to stay unmodified. The final call belongs to the inspection station technical head, so ask your station before installing it.
Where do you homologate an adjustable suspension in Argentina?
In Buenos Aires province, the VTV asks for a technical report signed by a mechanical engineer registered with the Colegio de Ingenieros de la Provincia or with COPIME. On top of that, Decreto 779/95 says the workshop that makes the modification issues a certification signed by a qualified professional. You take those papers to the inspection station, which decides whether they are enough.
Will my car fail the VTV if I lowered it by cutting the springs?
According to the 2026 Buenos Aires province manual, yes: a cut spring is a serious defect and cutting factory springs is prohibited. A serious defect means the result is RECHAZADO (rejected) and you cannot drive on public roads until you repair it and go back for a new inspection.
What happens with a conditional or rejected result in Buenos Aires province?
With at least one minor defect and no serious ones you get CONDICIONAL: you have up to 60 days to repair and come back, and you can keep driving meanwhile. With a serious defect you get RECHAZADO: you cannot drive on public roads until you repair it and go back for a new inspection, also within 60 days at most.
Does changing the wheel size affect the VTV?
In the Buenos Aires province manual, wheels of a size different from the original model are an observation, and a tyre sticking out past the fender is a minor defect. Nationally, Decreto 779/95 requires the wheel and tyre assemblies recommended by the vehicle or tyre maker.
Do I need a modified car to learn drifting?
No. In TROMPO classes you drive the school BMW E36 328i at El Picódromo, in Esteban Echeverría, with the instructor sitting next to you. Your own car stays out of it, and you do not need a driving licence: it is a closed track.
