Having only recently bought my p38 some have suggested to me to replace the air suspension to coil spring set up to enjoy the ride levels i had with the previos classic,has anyone done this for this reason or due to failures.

ask in the rr bit yooth.

some only replace with coils if the air is giving grief, though i would spend the cash on fixing it.
you havent said yours is playin up, so why change it?

oh arh, welcome an all that.
