D40 Diff ratio and bolt pattern?

[gunning1987]

Hey can someone tell me is there a different diff ratio of st and stx? Also are they a 10 or 12 bolt crown wheel, how many splines?

Cheers

So from what I've worked out the rear will take a R149 and the front R180, ratio could be 3.692 or 3.538 couldanyone help me narrow this down wanting to order lockers but need ratios and stud to clarify that theyll fit my car.

btw 2011 ST D40 thai built.
