what springs can be put on the G35x? and how much of a drop would i get? since the X sits higher then the other G35's is it ok to go with a lower drop spring like tein S tech? and does the front sway bar fit the X? what do u recommend for a rear sway bar.

Dont be lazy and use the search function. Ill be nice and answer your question anyways.

G35X Suspension options = NONE

There are some threads in here- Example:

There are no specific X model options- The Lower control arms are different, though I'm not sure what will fit and what doesn't fit.
Springs shouldn't be a problem, dampers shouldn't be a problem.
