Electric Power Steering for Classic Cars and Vintage Vehicles

Rediscover the joy of driving your vintage car

A heavy steering, painful maneuvers, parking that becomes a challenge: this is the daily reality for many owners of vintage and classic vehicles. MA DIRECTION ASSISTÉE offers the solution: an electric power steering kit designed and calibrated specifically for your model, without altering the authenticity of your car.

We are an official reseller of EZ Power Steering, a global leader in the design and production of electric power steering kits for classic cars for over 15 years. Whether you drive an Alfa Romeo, Porsche, Ferrari, Jaguar, Volkswagen, Toyota Land Cruiser, or any other vintage vehicle, our expertise ensures precise installation, adjustable assistance, and a completely invisible result from the engine compartment.

Electric Power Steering vs. Hydraulic Power Steering: What's the Difference?

Unlike a hydraulic system, where the pump is continuously driven and consumes 3 to 4 horsepower from the engine, even when driving straight, our electric power steering system only draws current precisely when needed, up to a maximum of 5 to 7 amperes during full maneuvers.

• No loss of engine power, unlike a continuously driven hydraulic pump
• No leaks, no maintenance: no hoses, belts, or power steering fluid
• Completely silent operation, preserving the distinctive sound of your vehicle
• Adjustable assistance via potentiometer or speed sensor, tailored to your driving style
• Built-in safety: in case of electrical failure, the steering reverts to non-assisted mode, just like the original
• Load-dependent assistance: stronger at low speeds for maneuvers, lighter at high speeds for precision

How Does the Assistance Work: The Concept of "Load-Sensitive"

We prefer to talk about "load-sensitive" assistance rather than "speed-sensitive" — a distinction that is crucial.

All our kits operate based on this load-sensitive principle, similar to most hydraulic systems. Essentially: at low speeds, the steering wheel is heavier, and the torsion bar experiences maximum torsion. A torque sensor detects this torsion, and based on this measurement, the ECU calculates the level of assistance to provide. As speed increases, the steering naturally lightens: the torsion bar then twists less, and the ECU reduces assistance accordingly.

The pulse generator is an additional feature, not always necessary but can offer added value. In kits equipped with a wiring harness with a potentiometer, the system relies on a simulated speed signal, manually adjustable: by turning the knob counterclockwise, a low speed is simulated, providing maximum assistance.

In some cases, it is also possible to directly connect the ECU to the vehicle's electronic speed signal. However, it is essential to note that this option does not necessarily enhance the driving feel (the car's sensitivity and steering sensation remain similar). For this type of configuration, we offer a specific wiring harness — and it is entirely possible to later convert a potentiometer wiring harness to an electronic speed pulse harness.

A Customized Electric Power Steering Kit, Calibrated for Each Vehicle

Each power steering kit is tailored for a specific model. The loads on the steering system are calculated vehicle by vehicle to determine the exact motor power required. This calibration precision makes all the difference in the steering feel, far more than a simple "universal" product.

Frequently Asked Questions About Power Steering for Classic Cars

Does electric power steering damage my classic car?

No. 90% of our kits can be installed without welding or drilling, using only the original mounting points. You can always revert to the original configuration.

How long does it take to install a power steering kit?

Between 4-7 hours and 8-12 hours of labor depending on access to the steering system, which varies from one vehicle to another.

Is the power steering kit approved for road and competition use?

Yes, our kits are TÜV certified for 90% of models and are authorized for road use (subject to insurance) as well as in competition (rally, historic rally, drift).

What happens in case of electrical failure?

The steering simply reverts to non-assisted mode, exactly as it was originally, without endangering the driver.

What is the difference between electric power steering and hydraulic power steering?

The electric version only consumes current when in use (5 to 7 amps during maneuvers), compared to a hydraulic pump that runs continuously and consumes 3 to 4 horsepower, even when driving straight.
