Thule offers a few main types, and knowing the differences will help you choose the right ones for your needs. The Thule roof bar sizing process really depends on which system you choose, so let's get you up to speed.

Types of Thule Roof Bar Systems

Thule WingBar Evo: The WingBar Evo is one of Thule's most popular systems. It features an aerodynamic design that minimizes wind noise and drag. These bars are known for their sleek, low-profile appearance. They are also incredibly easy to install and offer excellent versatility. If you're looking for a quiet and stylish option, the WingBar Evo is a great choice. The WingBar Evo is a really great all-around option.
Thule Evo Clamp/Rapid System: This system uses a foot pack that clamps onto your car's roof. This is a versatile option suitable for a wide range of vehicles, including the A4 Avant B8.5. The clamps securely attach to the roof rails, providing a stable and reliable base for your cargo. The Rapid System is super easy to install, which is a major bonus.
Thule SquareBar Evo: The SquareBar Evo is a more traditional roof bar system with a square profile. It's a robust and reliable option, perfect for carrying heavier loads or for users who prefer a classic design. The SquareBar Evo is often more budget-friendly.
Thule ProBar Evo: This is Thule's heavy-duty option, designed for commercial use or for those who need to carry exceptionally heavy items. If you're planning on carrying a lot of weight, the ProBar Evo is the way to go.

Each of these systems has different components, including feet, bars, and sometimes adapters. You'll need to choose the right combination based on your car's roof type and your carrying needs. Now, let's explore the key components of a Thule roof bar system and how they work together to provide a secure and reliable platform for carrying your gear. This information will help you understand the next steps in choosing the right Thule roof bar sizing.

Components of a Thule Roof Bar System

A typical Thule roof bar system consists of several key components that work together to provide a secure and reliable platform for carrying your gear. Understanding these components will help you choose the right system and ensure a proper fit for your A4 Avant B8.5.

Foot Pack: The foot pack is the part that attaches directly to your car's roof. There are different types of foot packs designed for various roof types, such as cars with raised rails, flush rails, or fixed points. For the A4 Avant B8.5, you'll likely need a foot pack that clamps onto the roof. The foot pack provides the primary connection between the roof bars and your car.
Load Bars: Load bars are the horizontal bars that run across the top of your car. They come in different lengths and profiles (like the WingBar Evo, SquareBar Evo, and ProBar Evo). The length of the load bars depends on the width of your car's roof and the type of cargo you plan to carry. The load bars provide the primary support for your cargo.
Fit Kit: A fit kit is a set of adapters that may be needed to ensure the foot pack fits perfectly on your car's roof. This kit often includes rubber pads, clamps, and other components designed to provide a secure and custom fit. The fit kit ensures that the foot pack fits securely on your car.
Locks: Many Thule roof bar systems include locks to secure the roof bars to your car. These locks help prevent theft, giving you peace of mind, especially when leaving your car unattended. Locks add an extra layer of security.

When choosing a Thule roof bar system, it is crucial to make sure all of these components are compatible with your car and the load you want to carry. Make sure to consider the total weight of your cargo to ensure that the roof bars and your car's roof can handle the load. Let's delve into the specific measurements you'll need for your A4 Avant B8.5 to get the correct Thule roof bar sizing.

Finding the Right Thule Roof Bar Size for Your A4 Avant B8.5

Alright, here's the part you've been waiting for! Getting the correct Thule roof bar sizing for your A4 Avant B8.5. It's not rocket science, but you need to pay attention to detail to get it right. Don't worry, I'll walk you through it step-by-step. To get started, you'll need to consider a few key measurements. The exact bar size will depend on the Thule system you choose. However, I can still provide you with an idea of what size you will need to look for.

Step-by-Step Guide to Sizing

Consult the Thule Fit Guide: The easiest and most accurate way to find the right size is to use the Thule Fit Guide. Go to the Thule website or a Thule retailer's website and enter your car's make, model, and year (Audi A4 Avant, B8.5). The fit guide will recommend the specific roof bar system and the correct bar length for your car. The Fit Guide does all the hard work for you!
Check Your Car's Specs: You can also find information about your car's roof measurements in your owner's manual or by searching online. Knowing the distance between your car's roof rails (if it has them) or the width of your roof will help you narrow down your options. However, the Fit Guide is still your best bet.
Consider the Accessories: Think about what you'll be carrying. If you're planning on using a cargo box or other accessories, make sure the bar length is compatible with those items. Some accessories require a specific bar length to fit properly. This is crucial for optimal usability.
Measure Your Roof (If Necessary): In some cases, you might need to measure your roof. Measure the distance between the roof rails (if your car has them) or the overall width of the roof where the bars will sit. This measurement will help you determine the correct bar length. Be super precise when measuring, as a small difference can affect the fit.
