Anyone maneuvering an old Beetle or Karmann Ghia for the first time is usually surprised by how much muscle it takes. The original steering is heavy, indirect, and turns every turning maneuver into work. That's not a defect – it's simply the state of the art from back then. But there is one conversion that fundamentally changes exactly this driving feel: retrofitting rack-and-pinion steering. We documented the complete conversion on a Karmann Ghia Type 14, including a before-and-after test drive, and here we show you what the conversion delivers and how it's done.
Why Old Beetles Steer So Sluggishly
On the test drive before the conversion, the Karmann showed the full program: very heavy steering, a large turning circle, plenty of wheel-winding in roundabouts, and steering at a standstill or while reversing gets genuinely strenuous without power steering. The fitted balloon tires amplify the effect even further. Then there's the design of the old system: between steering wheel and road wheel, a steering box, a complete steering linkage and a steering damper are all at work, and during the conversion all of it has to come out piece by piece. For relaxed cruising you can live with it – an old car doesn't have to drive like a new one. But if you want more driving fun and use the car regularly, rack-and-pinion steering brings a piece of modern drivability into the vehicle without having to install power steering.
What the Conversion Kit Includes
The heart of the conversion is a new steering rack from the VW Polo 86C – proven mass-production technology that's available as a new part. The kit installed in the video is deliberately not the usual cheap conversion kit: brackets and adapters are machined from solid aluminum, the rod ends are uniball-mounted instead of rubber-bushed, and the universal joint is custom-made. The uniball mounting makes the steering more direct because the soft rubber play is eliminated – in exchange, slightly more vibration tends to reach the steering wheel. The whole thing costs more than simple kits, but the workmanship and material quality are significantly higher.

How the Conversion Works
- Create access: On the Karmann, the fuel tank has to come out first to reach the steering.
- Remove the old steering: Loosen the tie rod ends, then remove the steering box, steering damper and the complete steering linkage, followed by the steering column.
- Mount the bracket: The new bracket goes onto the frame head, with about 5 mm of clearance according to the instructions. Its angle is adjustable, which matters on the Karmann because the steering column sits slightly differently than on the Beetle.
- Adapt the steering column: The original steering shaft is shortened, and an adapter connects it to the new universal joint. In our case, the adapter still had to be turned down slightly on the lathe to fit into the steering shaft.
- Mark the center position: Bring the steering rack to its center position, fit the steering wheel straight, and pay attention to the detent position of the steering lock while doing so. Overlook this, and later the key will only engage after several turns.
- Drill and weld: According to the instructions, the connection between steering shaft and adapter gets three cross-drilled holes and is welded. For safety, we add extra welds.
- Fit the tie rods: For the conversion you need two tie rod ends with right-hand threads. Assemble the threads with assembly paste, because if the thread seizes, you'll have a bad hand when adjusting the toe later.
- Adjust: Finally, the steering stops are set, followed by the toe.
Don't Forget the Registration
A steering conversion intervenes in a safety-relevant system, so registration is required here. It's best to discuss this with your inspection office before the conversion – then there are no surprises afterwards.
The Result on the Road
The before-and-after comparison in the video was unambiguous: the car steers much more easily, the steering works more directly, the Karmann no longer floats as much in corners and can be moved through bends noticeably faster and more sportily. A car that previously drove sluggish and lumpy became one that's genuinely fun.
A side note from the same conversion is worth mentioning: at the rear, a coilover setup was installed that, in our view, didn't properly match the swing axle. It was swapped for classic Bilstein dampers, and only then did the overall handling come together. Steering, dampers and axle have to be thought of together – a single component doesn't make a well-rounded car.
Who the Conversion Is For
The objection arrived by email even before the conversion: an old car is supposed to drive like that. That's true too, and if you want to keep your vehicle as original as possible, leave the steering as it is. The conversion is aimed at drivers who use their Beetle or Karmann Ghia regularly and want more driving fun and less effort: relaxed maneuvering, precise turn-in, a car that drives closer to today's standards. Especially in combination with a power-tuned engine or a sportier suspension, proper steering belongs to the complete package – which is why we also fit rack-and-pinion steering in our complete builds.
If the Car Still Tracks Crooked
New steering improves the steering feel, but it doesn't repair crooked geometry. If a Beetle pulls to one side or never runs cleanly straight, the cause often lies in the frame head: if it sits offset by a few millimeters or the control arm mounts are out of tolerance, the car tracks crooked no matter which steering is installed. We check and straighten the frame tunnel and frame head on a massive frame jig, with measuring points on the Napoleon hat and the frame head as well as test pins for the control arm mounts. We show what that looks like in this short video. You'll find matching parts for axle and steering in our Beetle Front Axle and Beetle Steering categories.
Conclusion
Hardly any conversion changes everyday driving in a Beetle or Karmann Ghia as noticeably as rack-and-pinion steering: less effort, more precise turn-in, a modern steering feel without power steering. The conversion itself is doable, but it demands clean work when adapting, aligning and welding the steering column. If you don't want to do it yourself, we'll install the steering in our workshop in Rahden. Get in touch with us and we'll discuss what your vehicle needs.
