Front control arms for some Audies were redesigned throughout its years of production.
You can discern the correct parts by checking the build date of your car.
The biggest change was the size of the hydro bushing and the thread size of the ball joint for the knuckle. The bushing ranges in size from 65mm to 75mm and the balljoint ranges from M12-M14.
Besides decoding your built date by VIN, the other way to identify the correct control arms is to find part numbers on the control arms currently installed on your car.
To start shopping for suspension parts for your vehicle, head over to Fcpeuro.com and enter your vehicle information into the fitment selector.
Once your car is added to the selector, there are a couple of important ways that we advise correct fitment.
The first is the "fitment indicator" shown on the Product Page after selecting a part. This box is below the "add to cart button" and has two states. It will either say " Yes this part fits" or "Part may not fit, click to verify".
Sometimes the green box will be accompanied by extra fitment notes. These notes may be independent of the information gathered by the vehicle selector. IE: VIN-specific options, need to be taken into account when determining overall fitment.
