Really, how much cheaper are the coil springs though? So you're saving $238. Really not that much.
Coil Spring Conversion FRONT AND REAR $390
Stock FRONT ONLY Air Struts $350-500 (add $200 for new rear air springs)
Now.....you've just converted to coils and you never have to replace ANY other part of the "suspension" until the struts go again(your broken spring theory is 1 in a million, so its not valid)
Here is a list of ALL the parts related to the factory air suspension.....how much are you really saving in the long run? If the compressor fails next month because its been working soo hard to pump up bad bladders, or a failed level sensor, or a stuck open solenoid...its another 300 bucks(or whatever they are)....

Its your call JRM.....you want functionability w/worry for the dreaded "Check Air Suspension" or do you want reliability, economical, replacement with the same or better ride quality(matter of opinion I guess)?
