Individual Vehicle Approval (IVA)

Owners of one-off, low volume and continuation series cars now have the opportunity to enjoy them on the road thanks to our new ‘IVA compliance’ service. Having engineered and fitted Individual Vehicle Approval (IVA) compliance kits for the Aston Martin DB4 GT, we have now expanded this service to other cars.

A solution for continuation series, one offs and converted cars

Available for all continuation series, limited production and one-off vehicles, as well as electrified classic and performance cars, our IVA compliance services involve parts developed and fitted by ourselves before registering the car for full UK road use.

IVA involves checking that vehicles meet the modern environmental, driver and pedestrian safety requirements laid out in European legislation and applies to imported as well as low volume vehicles. Whilst the UK’s IVA maybe accepted in other countries under ‘mutual recognition’ agreements, R-Reforged has extensive experience acquiring local equivalent approval for bespoke cars such as Ferrari 599 Zagato, Aston Martin DBR2 racing car, Land Rover DEFENDER WORKS V8 70th EDITION and Lamborghini Gallardo Zagato Spyder.

Seamless integration 

To date, seven of the 25 DB4 GT Continuations have already been sensitively upgraded with a fully reversible kit that incorporates over 60 changes undertaken by our engineering team. Each respects the original design whilst meeting the stringent standards required to gain approval. Modifications incorporate a smoother octagonal wheel nut, E-marked side and rear windows, new trim parts with smoother radii to minimise sharp edges and upgraded lighting – including the addition of discrete side repeaters along with a retractable fog lamp. To meet pedestrian safety standards, other modifications include replacing the ‘slashed’ exhaust tips with rolled versions and the removal of the front fog lamps. Inside, as well as changes to the steering wheel, instrumentation and fitting an immobiliser, the roll cage receives a trimmed, matching leather cover. 

Rigorous approvals 

R-Reforged has ensured cars such as the DB4 GT can achieve modern EU emission targets with the period engine design. R-Reforged has developed an integrated silencer and catalyst system. Combined with engine tuning and changes to the fuelling system, cars such as the Aston Martin DB4 GT can now meet UK emissions standards, enabling them to be enjoyed on the road.

Comprehensive service – from start to finish

Each vehicle is different but typically the process can take around 10 weeks including arranging the IVA test itself. Each car is returned to its owner with a tailored ‘campaign case’ to store the exchanged parts, ready to revert the car to its original factory configuration if ever required.
