Hi All,
Just got back from the dealer (purchased a new 2012 R/T), pretty stoked about it!
I read through this thread before hitting the dealer and was on the lookout for brake sizes. I can confirm that the dealer had some new SXTs (FWD) on the lot that HAD the larger brakes (same as the R/T).
Only the newest vehicles had them, and coincidentally all SXTs that did have them, also had different 17" wheels that I had not seen before. They were 5-spokes, but I didn't get a pic of them. Maybe someone else will be able to confirm this?
