To find the rear track width of a 2007 Audi S4, I recommend checking the following sources:
* Audi's official website: Look for the specifications section for the 2007 S4 model.
* Reputable automotive websites: Websites like Edmunds, Car and Driver, or Autotrader often have detailed specs on specific vehicles.
* Owner's manual: The owner's manual for your 2007 S4 should contain this information.
* Vehicle identification number (VIN) decoder: You can use a VIN decoder online or through an auto parts store to retrieve detailed information about your car, including track width.
Remember to ensure the information you find is specific to the 2007 model year and the S4 trim level.
