A P38 on springs is bad. Castrated! I know this will probably set off an Air / springs debate that has raged on and off intermittantly for god knows how long. but here it is.
the EAS system is inherently simple. it gets ripped out and replaced by people that havent got a clue. The upshot is, an air bag leaks, the compressor works overtime, the air bag is replaced. the next air bag leaks, compressor working overtime feeding a leak again. It's replaced, by the time all 4 have gone through the compressor is knackered then it gets the press of being unreliable. all 4 springs were fitted at the same, rubber deteriorates at the same rate no matter which corner so if one is leaking. replace them all, the next and the next and the next wont be far behind. if the valve block is overheauled the compressor overhauled (as per my previous post) there shouldnt be a problem. its a lack of unerstanding of the vehicle itself that leads to air being replaced.
now the practical side. The P38 EAS is self levelling. no matter what weight you put on the back the EAS sytem will level the car. hence the headlights do not have dash adjustment. The EAS system lowers the car when above 50MPH for more than 30 seconds, this is for safety at higher speeds by having a lower CofG. when offroading, the EAS will push a wheel down when loss of contact occurs. also the ride of the P38 is built around the P38.
personally i wouldnt touch a castrated P38 with a bargepole. It is also worth bearing in mind that mooted EU regualtions for modified vehicle could render a catsrated P38 non-compliant, also with the loss of headlight leving capability... I'm not sure if that is requirementioned for compliance.
So now I've lighted the touch paper on this debate I'll retreat to safe distance
