    My 09 RT auto had a 215 mm. I just changed it to the Getrag 226mm. To my knowledge no challengers had the 210 mm rear.

    09 Challenger RT Auto: port matched shorty headers, catless mids, Magnaflow catback, home ported TB, 180 stat, modified stock air intake, M&H DR's, Predator with DCX Depot CMR.

    You both have 09's and your stock set up is a 215mm 3.06? I'm getting ready to install a 3.73 LSD Getrag in an 08 Chally SRT8! Just wondering what are the options for factory rears.
