I thought the modern dodges were 115mm bolt pattern. It wasn't until you mentioned it that I took another look and it seems like they switched from 114.3 to 115 in 2013. Its looking like the Challenger RT rotor may work, or at least be very close to working. It is slightly larger at 13.6" vs. the 13.25", but I seriously doubt that will have a big impact. I'm going to go grab a rotor from the local parts store to see if it will work.

There has been a huge disagreement on what the bolt pattern is on the LX/LC cars. I've found info on RockAuto showing the bolt pattern for the earliest cars at 5x4.5", and even measured a steel wheel myself and found the same. Yet most of the published data shows 5x115. I finally gave up and couldn't tell you what the real number is.

Regardless, I wouldn't worry about it unless you were looking at running LX/LC wheels. The brake rotor just needs to slide over the studs and be flush with the face of the hub. Beyond that it really doesn't matter.

Be aware that the 13.6" rotor is not as deep as the 14.2" rotor I linked. It is only 2.15" tall overall and will only give you an additional 1/4" of clearance compared to the Mustang rotor.
