As a world-leading manufacturer of tuning adapters, we develop tailor-made solutions precisely matched to your vehicle and your requirements – TÜV-approved, individually manufactured, and 100% Made in Germany.

Our expertise, gained from over 15 years of experience, makes us the ideal partner for modifications where standard solutions fall short. Do you want to install modern rims, upgrade to a more powerful brake system, or noticeably improve your suspension? With our adapters, your classic car becomes a well-thought-out tuning project – technically sound, visually stunning, and easily registered.

The Opel Corsa A TR – A lightweight classic with great tuning potential

The Opel Corsa A TR, with type codes 91, 92, 96, and 97, was built in the 1980s and early 1990s and stands for compactness, low weight, and robust engineering. As a three-door, five-door, or special edition, it remains a popular entry-level vehicle for the tuning world – and for good reason: its straightforward engineering makes it highly versatile.

However, implementing modern technology on the Corsa A TR quickly reveals hurdles: rims with a different bolt pattern cannot be easily mounted, more powerful brake systems do not fit the standard mounting, and chassis components from newer models require precise transitions.

This is where our tuning adapters come in – because they solve exactly these problems. Each adapter is manufactured to fit your vehicle perfectly and allows you to integrate modern technology safely, in compliance with TÜV regulations, and with a visually appealing finish.

Brake adapters – More braking power for your Corsa A TR

Improve braking performance – but do it right

The standard braking system of the Corsa A TR was designed for everyday driving and the base engine. But as soon as you drive more sportily, fit wider rims, or install a more dynamic suspension, you quickly reach the limits of the original system. Our brake adapters allow you to safely install larger brake calipers and higher-performance brake discs – for example, from models like the Kadett E GSI, Astra F, or even from the VAG group.

The adapters ensure precise positioning and reliable attachment – so that your new brake system not only fits, but also delivers noticeably more control.

Advantages at a glance

• Compatibility with numerous brake systems
  
  
• Improved braking performance and safety
  
  
• Easy assembly thanks to precise manufacturing
  
  
• TÜV-compliant with documentation
  
  

This is how you bring the technology of your Corsa A TR up to today's standards – functional, safe and visually appealing.

Wheel adapters – For rims to your liking

The rims you want – finally possible

For many tuning enthusiasts, choosing the right rims is a key consideration. However, the 4x100 bolt pattern on the Opel Corsa A TR limits the selection. Our wheel adapters allow you to easily mount rims with different bolt patterns – such as 5x100 or 5x112 – opening up numerous design and performance options.

Furthermore, you can adjust the track width of your vehicle by changing the thickness of the adapters – which not only looks good but also noticeably affects the driving behavior.

This is what our adapters can do

• Mounting rims with a different bolt pattern
  
  
• Wheel spacers for improved appearance and handling
  
  
• Made from high-strength aluminum – lightweight & durable
  
  
• TÜV-compliant and individually manufactured
  
  

Give your Corsa the look you've always imagined – without compromising on safety or registration.

Suspension adapters – More control and sporty handling

Your chassis, your driving experience

The Corsa A TR's suspension components are from a different era – and offer little room for sporty tuning. If you want to upgrade to coilovers, replace strut mounts, or use control arms from another model, you need precise adapters. Our suspension adapters make exactly that possible.

They connect your new components to the existing axle design – safely, stably, and in compliance with TÜV regulations. You get more control, a more direct steering feel, and a suspension setup that suits your driving style.

Advantages of our chassis solutions

• Integration of modern chassis components
  
  
• Improvement of track and camber conditions
  
  
• Robust construction for long durability
  
  
• TÜV-compliant with technical documentation
  
  

This way you not only lower the appearance of your Corsa A TR – but also take its driving performance to a whole new level.

FAQ about Epytec tuning adapters for the Opel Corsa A TR

Question 1: Which brake systems can be fitted to the Corsa A TR?

Our brake adapters allow you to install systems from models such as the Astra F GSi, Calibra or Kadett E. This enables you to use ventilated discs, stronger calipers and larger diameters – perfect for sporty driving.

Question 2: How does the offset depth change when using wheel adapters?

The effective offset depth changes by the thickness of the adapter. For example, if you use a 20mm adapter, the wheel will "move" 20mm further outwards. This affects the appearance and can positively influence the handling – we'd be happy to advise you on this.

Question 3: How complicated is the TÜV registration of your adapters?

Our adapters are designed to be TÜV-compliant. You will receive all necessary technical documentation with the product. Registration is usually straightforward, depending on the federal state; many customers report smooth approval processes.

Question 4: Are there also custom-made products for special modifications?

Yes, we also offer custom-made products – for example, for motorsport conversions, combinations of different brands, or complex wheel/axle concepts. Just get in touch, we'll advise you personally and develop a solution for your project.
