2014 Regal 2.0T. Which front rototrs?
I have a 2014 Regal 2.0 T. I need to replace the front rotors and there are two different sizes listed for it. I am not looking at the GS rotors, those are completely different. The two sizes are 296mm or 321mm. How do i know which ones I need. I am ordering parts online so I cant just pull one to compare, and I dont have the proper tools to measure.
