Hi Chris... I have problems with the air suspension leaking and my local dealer told me they can replace the bags but that they will eventually go bad. They say it is not a matter of if, but when they will go bad. So, I am strongly considering coilovers but I don't really want to lower the vehicle. How did yours affect the ride height? Did you put the KW COs? Do you have any pics? Sorry for the temporary hijack and thanks for any info.
