When it comes to purchasing brake rotors and pads for your vehicle, it's important to select the right size. However, there are often multiple sizes available, and they are not interchangeable. The rotor size you need may depend on various factors, such as your car's trim, country of origin, sports/performance package, transmission type, engine size, and more. To help you confirm the correct fit, we have a few suggestions.

First, check the vendor's catalog fitment notes. However, keep in mind that these catalogs can be incomplete, and your specific model/trim may not be listed. Alternatively, you can contact your local OEM dealer and ask for the original rotor sizes or OEM rotor/pads part numbers based on your vehicle's VIN number. This is a reliable way to get the genuine part numbers for your car, but note that if your vehicle has been upgraded with HD/performance brakes at a later date, the dealer may not be aware of this.

Another option is to measure the outside diameter of your rotors and match it with the listed properties of the replacement. A reputable vendor should have documentation on their nominal rotor sizes and types and provide this information upon request or on their website. However, this method requires some effort as you need to take off your wheels to measure the rotor's edge-to-edge distance through the rotor center.

It's also important to note that vented and solid rotor options are not interchangeable in most cases. For example, if your car has a solid rear rotor, you will need to upgrade your calipers before fitting a vented rotor.
