Testing vehicle modifications and conversions

Have you converted a vehicle or would you like to modify a vehicle with existing components? We test everything.

The DTC has a modern testing infrastructure. Thanks to this, we can examine your conversion in terms of operational and road safety.

We specialise in subsequent modifications and offer you flexible and prompt modification tests for national or international approvals.
