GCK Performance

Global integration of mechanical systems

With high-performance tools and the recognised ingenuity and agility of our teams, we work on industrial projects for special vehicles, racing cars and the mobility of the future. The sum of our skills enables us to manage these projects in their entirety and often in a very short time.

Project management

Management is a key factor in the success of a project, especially when it is an evolving prototype for which it is more difficult to define a precise scope. From the definition of the objectives to the delivery, we accompany our clients in all the phases of the collaboration by carrying out a daily follow-up, by anticipating the risks and the changes to be implemented, by deciding, and especially by communicating.

  • Analyse needs
  • Building and planning
  • Conducting and managing
  • Close and evaluate

Design office

The team – made up of experienced designers, modelers, engineers and designers – supports our clients from the creation of the specifications, by developing technical scenarios that allow informed choices to be made with regard to the constraints (quality, cost, time). The mechanical systems we design are optimised to integrate the latest technologies in terms of motorisation and on-board electronics in all areas of mobility. Everything is designed to optimise the performance, reliability and safety of your vehicle.

  • Reverse engineering
  • CAD
  • Structural calculations
  • Dynamic simulations
  • CFD

Methods Office

GCK Performance develops its own tooling necessary for the production of one or more vehicles in order to optimise quality and manufacturing times. We benefit from a large autonomy thanks to our workshops and our network of qualified subcontractors.

The tools we manufacture can be delivered to the customer in a logic of industrialisation of his production line, or used by our teams on the GCK Performance site in Issoire.


Our machines allow us to produce complex high precision parts, individually or in small series, by machining or turning, in steel, stainless steel and aluminium. Each manufactured part is checked and can also be traced using laser marking.

We manufacture complex assemblies such as tubular frames, suspension triangles or safety hoops on site (bending, folding, cutting, welding).

GCK Performance also relies on a network of specialised subcontractors, in particular for the manufacture of parts in composite materials.

  • Boilermaking
  • Mechanical welding
  • Machining
  • Metrology


We have two assembly halls where we can assemble up to 14 vehicles simultaneously. Each bay is equipped for the assembly of a car, such as our Delta Evo-e RX, which consists of more than 2,000 parts in metal, plastic, carbon fibre, etc.

As part of the GCK group, our company is specialised in the integration of electric and hydrogen power trains. Our technicians are trained to handle these technologies in complete safety.

The draughtsmen in the design office directly supervise the assembly of the prototypes, paying attention to the smallest details, with a degree of requirement that has led the racing team to victory in several disciplines.

All components, from the smallest nut to the most complex assemblies (such as gearboxes), are stored in our warehouse.

Operation, analysis, development

With its experience in motor sports, our team assists its clients in the deployment of a test programme. It has the know-how and tools (workshop trucks, software, Charade circuit) required to carry out an optimisation campaign.

In concrete terms, on-board instruments and sensors collect digital data which we then analyse to understand the dynamic behaviour of the vehicle and optimise it to achieve the previously defined performance criteria.

Our GCK Motorsport operations team has distinguished itself in several high-level disciplines such as the Dakar Rally, the World Rallycross Championship and the Andros Trophy.
