Product Information

Audi Fender diagram for TTS Quattro, TT Quattro, TT, TT RS Quattro

A fender brace is a structural support piece that connects the vehicle’s fender to the body or frame. Its main role is to provide rigidity, reduce vibration, and maintain proper alignment of the fender and surrounding panels. By reinforcing this area, it helps ensure stability at higher speeds and prevents flexing or rattling of the fender. Fender braces are usually made of metal and can weaken over time due to stress, corrosion, or collision damage.

• Panel misalignment – fender appears loose, shifted, or doesn’t line up properly with adjacent panels.
• Noise or vibration – rattling, shaking, or fluttering of the fender, especially at speed.
• Reduced structural support – brace shows visible rust, bending, or cracking, compromising fender stability.

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Audi parts box and find an OEM branded part inside, simply with the addition of an Audi logo.
