Coil Springs for a 1997 Y60 TD42

[npca-marius_the_virus]

  Can someone please please provide some sound advise.   I want to replace my stock coil springs.  What options have I got?  I live in Panama, Central America, so a US or Latin America distribnuitor would be very good.  I already replaced the stock shocks for a set of Rancho 5000.  Have you replaced your coils on a Y60?   If so, What brand, model, etc.  you used and why?   How are the new coils doing?  Things like that so I can decide what´s best for me. Thanks in advance for any input... I could find out about a US dsitribuitor for both OME and Ironman, what do you think?
