i had this issue with my Disco 2 a few years ago. on the D2 only the rear end was air, but because they were seven seaters and the air supported the weight etc etc it was illegal if i am correct to convert to coils unless you removed the rear seats.

thats why most people who wanted a suspension lift, did the normal lift on the front, but put alloy spacers on the axle then the air bags and extended the sensor arms to keep everything in line. Current: TDV8 (3.6) RRS HSE
