Porsche 911 Carrera 4 Cabrio 993 Tuning – Tailor-made solutions with Epytec adapters

The Porsche 911 Carrera 4 Cabriolet (993) is considered by connoisseurs to be the last "true" 911 with an air-cooled boxer engine – a timeless vehicle with a unique character. The combination of iconic design, mechanical driving feel, and all-wheel drive makes the 993 Carrera 4 not only a highly sought-after classic but also the perfect basis for high-quality tuning. Those who choose this model primarily want one thing: to harmoniously develop the technology and aesthetics. With our tuning adapters, you can achieve exactly that – precisely, safely, and in compliance with German vehicle inspection regulations (TÜV).

At Epytec, we've been developing custom tuning adapters for demanding conversion projects for over 15 years. Our solutions are manufactured in Germany, specifically tailored to your vehicle, and give you maximum freedom in choosing brakes, wheels, or suspension components. Whether you want to subtly enhance your 911 or prepare it for track days – with Epytec, you get exactly the technology you need.

The Porsche 911 Carrera 4 Cabriolet 993 – Air-cooled. Legendary. Tuning-ready.

Built from 1994 to 1998, the 993 is the final iteration of the classic, air-cooled 911. As the Carrera 4 Cabriolet, it combines open-air driving pleasure with sporty all-wheel-drive technology – a rare package with great potential for customization. However, especially with a model that is almost 30 years old, modern components often reach their technical limits.

Whether you're upgrading to modern wheels with a different bolt pattern, more powerful brakes, or a custom-tuned suspension – many parts simply won't fit without extensive modifications. Our tuning adapters bridge this gap. They allow you to mount state-of-the-art components safely and securely on your 993 – without compromise and with full TÜV approval.

Wheel adapters – New possibilities when choosing rims

Few things change the look of a vehicle as dramatically as the wheels. But especially with the 993 Carrera 4, the selection is limited – because many modern wheels have different bolt patterns. Our bolt pattern adapters provide a solution.

They allow you to safely mount rims with a different bolt pattern on your Porsche. At the same time, they offer you the option of adjusting your vehicle's track width – which not only offers visual advantages but also significantly improves handling.

Our adapters:

• consist of high-strength aluminum
  
  
• They are manufactured specifically for your vehicle
  
  
• They are TÜV-friendly for trouble-free registration.
  
  
• offer stable connection & centered mounting
  
  

This allows you to choose from a variety of modern rim designs while simultaneously improving handling and appearance.

Brake adapters – performance and safety in harmony

As performance increases or larger wheels are fitted, so do the demands on the braking system. The standard brakes on the 993 are solid – but not designed for today's performance requirements or sporty use on the racetrack. Our brake adapters allow you to upgrade to modern braking systems from the Porsche parts bin or the motorsport sector.

With our adapters you can use brake calipers and discs from models such as the 996 Turbo, 997 GT3 or even the Porsche Cup – depending on your wishes and project goals.

The advantages at a glance:

• Significantly improved braking power
  
  
• Less fading at high temperatures
  
  
• Shorter braking distances, more control
  
  
• Secure and stable installation thanks to precise fit
  
  

Our adapters are designed for maximum durability and take your vehicle to a new level in terms of safety and performance.

Chassis adapter – Precise driving dynamics for more control

The 993 is known for its well-balanced handling – but those who want more need to fine-tune the suspension. Especially when combining different components, fitment issues often arise. This is where our suspension adapters come in.

They enable the assembly of:

• coilover suspension
  
  
• Clubsport and track suspensions
  
  
• reinforced wishbones or motorsport solutions
  
  

With these adapters, you can individually adjust camber, toe, and ride height, precisely tailoring the handling of your 993 to your driving style. Whether you prefer a sporty daily driver or a racetrack setup, Epytec suspension adapters provide the foundation for uncompromising driving pleasure.

FAQ about Epytec tuning adapters for the Porsche 911 Carrera 4 Cabriolet 993

Question 1: Can I also use motorsport components with your adapters?

Yes, many motorsport parts require special adapter solutions – and that's exactly what we offer you: perfectly fitting products. Simply provide us with the technical specifications of your components, and we'll deliver the ideal solution for safe installation and TÜV-compliant implementation.

Question 2: Which rim sizes can be achieved with bolt circle adapters?

With our adapters, you can mount almost all common wheel sizes – such as 18", 19", or 20", depending on the offset and available space. We help you find the right combination and always ensure clearance and technical feasibility.

Question 3: Are your brake adapters also suitable for track day use?

Absolutely. Our brake adapters are made from extremely durable materials and are designed for high thermal loads. This makes them ideal for use on the racetrack – whether with near-standard brakes or motorsport components.

Question 4: Are there any special instructions for suspension adjustments for the 993 Cabriolet?

Since convertibles exhibit more body flex, we particularly recommend paying attention to proper tuning and high-quality components, especially with lowered suspension setups. Our adapters allow for precise adjustment and combination with reinforced suspension components – ideal for everyday driving and sporty performance.
