We have also found that the 08 GT rear limited slip differential is compatible with the 2.5i manual transmission and this has been successfully mated to take advantage of the performance and safety gains vs the open diff on the stock setup. The 05-07 5MT rear differential is also theoretically compatible with the 4EAT transmission as the ratios are the same at 4.111:1 but this has not been attempted on any cars yet.
If I am reading this correctly, stock differential(s) on a 2.5i are open? Both front and rear?
This is a question I've had for some time (I have an '05 and an '09 2.5i), and this is the closest to an answer I could find by searching.
