Tuning for the Ford Sierra GBC, GBG – More than just a classic

The Ford Sierra hatchback in its GBC and GBG variants is a true child of the 80s – distinctive, unique, and with a design that stood out then as much as it does now. If you own this car, you know: it has more potential than meets the eye. And that's precisely where we at Epytec come in – with our high-quality tuning adapters, specifically manufactured for vehicles like your Sierra.

While many modifications to modern cars are almost routine, the Ford Sierra requires a certain finesse. Bolt patterns, axle designs, and mounting points aren't always compatible with today's components. If you want to install modern brakes or contemporary rims, you need precisely fitting solutions – without compromising safety or TÜV compliance.

Our adapters are manufactured in Germany, are TÜV-compliant, and give you the freedom to integrate virtually any component as desired. Whether you're installing a new brake system, widening your track, or have a custom wheel design in mind – we provide the perfect connection.

The Ford Sierra GBC, GBG – a tuning base with character

The Sierra hatchback was a design revolution in the 80s. With its streamlined silhouette and distinctive rear end, it stood out significantly from the otherwise angular vehicle designs of its time. The GBC and GBG variants, in particular, with their rear-wheel drive, still offer a solid platform for individual modifications – whether for everyday use or as an entry into motorsport.

But the technology of that era has its drawbacks: Many modern rims don't fit without modifications, brake systems require special brackets, and axle conversions are almost impossible without custom-made adapters. This is precisely where we come in – with over 15 years of experience and a clear focus on your freedom to customize your vehicle.

Our tuning adapters make your Sierra compatible with components from current model series – whether Ford, BMW, or Audi. This allows you to combine classic design with modern technology. And the best part: each adapter is manufactured according to your project specifications – no compromises, no workarounds.

Wheel adapters for your Sierra – unlimited wheel variety

Finding your style on the Ford Sierra hatchback is easy – but finding the right rims isn't always simple. Many aftermarket designs or those from other models have different bolt patterns. Our bolt pattern adapters solve this problem easily and reliably.

Advantages of our adapter solutions:

• They allow the mounting of rims with a different bolt pattern.
  
  
• Expand your selection to include virtually any modern rim design.
  
  
• Stable, lightweight and made of high-strength aluminum
  
  
• Optimize the track width and improve driving dynamics
  
  
• TÜV-compliant and safely registerable
  
  

Whether you prefer classic motorsport looks or a modern deep dish – our adapters make your dream rims a reality. And thanks to precise manufacturing, everything fits securely and without any play.

Brake adapters – More control, more performance

The standard brakes on the Ford Sierra are often no longer sufficient for today's demands. Especially with sporty driving, larger wheels, or increased vehicle weight, you should consider upgrading your brakes. Our brake adapters allow you to convert to more powerful systems – for example, from the Ford Mondeo, the Focus RS, or even BMW models.

With our solutions you can:

• Install brake calipers and discs from more powerful vehicles.
  
  
• Increase braking power in a targeted manner and shorten the braking distance.
  
  
• Experience better pedal feel and less fading.
  
  
• Easily implement a TÜV-compliant registration
  
  

Especially with combined modifications involving chassis, rims and brakes, choosing the right adapter is crucial – we are happy to advise you individually so that you get the best out of your project.

Wheel spacers & axle adjustment – For perfect road holding

A sporty driving experience is the result of many details – and the correct track width is one of them. With our adapter plates, you can specifically improve the axle geometry of your Sierra. This affects not only the appearance but also the driving characteristics.

Our wheel spacers:

• Create space for larger rims or wider tires
  
  
• Improve cornering stability and steering response
  
  
• Support with conversions to other axle systems
  
  
• Made of robust aluminum – for long-lasting stability
  
  

Especially with the Ford Sierra, with the right combination of adapter, track widening and brake system, you can unlock the full potential of the platform – and experience a completely new driving sensation.
