Police spec is a bit bogus. They simply didn't buy that many in terms of production numbers.
Chart here: http://www.red90.ca/rovers/springinfo.html
Says these rates from 87 thru 91 for the rear:

So I guess the valve block which levels the vehicle is redundant perhaps JLR should have just fitted tyres to each corner
Bored now.

Clearly you don't know much about how this all works....So I guess the valve block which levels the vehicle is redundant perhaps JLR should have just fitted tyres to each corner

@300bhp/ton , only you mentioned the spring adjusting every second,see#post 120.unlike a tyre the suspension will adjust height, lowering to motorway height or as you put it low ride height if a speed of over 50 mph is attained and will return to standard when the speed drops unless the inhibit switch is activated ,I believe Keith runs his vehicle in this mode all the time. The vehicle will also self level when parked and will do so every six minutes unless the self leveling relay is pulled, usually for checking for leaks, but hey I know nothing but I don't call other members, who have a vast range of knowledge, dicks because they have their own views.Spot on

Think outside, no box required.
The Police loved the RRC they used them and the P38 as patrol cars and yes police spec springs are available for the rear, I fitted a set to my 91 Vogue because the self levelling strut was defective, they worked well Red/White band IIRC, they only do them for the rear, obviously because the police don't carry their kit on the bonnet....
The springs listed for 87-91 in the chart are HD springs, the difference between a stock RRC spring and a D1 spring is vast, but still less than what is listed as the 87/91 springs, even a disco rear spring is 209 lb/in and a current rrc heavy duty is 170 ib/in IIRC..
So no something is wrong there..
A 178/280LB rear spring on a classic would be hideous, even the current HD springs are only 170Lb..

I do run the car locked at motorway height, 5 ups and downs on a 30km run to the shops was ridiculous.@300bhp/ton , only you mentioned the spring adjusting every second,see#post 120.unlike a tyre the suspension will adjust height, lowering to motorway height or as you put it low ride height if a speed of over 50 mph is attained and will return to standard when the speed drops unless the inhibit switch is activated ,I believe Keith runs his vehicle in this mode all the time.

the EAS self levels about every 6 hours when parked not every 6 minutes.

The spring does not continually adjust. Else the wheel wouldn't be able to go up and down over bumps.@300bhp/ton , only you mentioned the spring adjusting every second,see#post 120.unlike a tyre the suspension will adjust height, lowering to motorway height or as you put it low ride height if a speed of over 50 mph is attained and will return to standard when the speed drops unless the inhibit switch is activated ,I believe Keith runs his vehicle in this mode all the time.

So again, which bit are you not getting about adding more air & pressure will lift the vehicle? This seems to be the bit you keep debating, then deflecting on.

The Police might have opted for the HD springs. But so could other people. They are not 'Police spec'. You are dressing it up as though they are something they are not. They were just an alternative spring rate.The Police loved the RRC they used them and the P38 as patrol cars and yes police spec springs are available for the rear, I fitted a set to my 91 Vogue because the self levelling strut was defective, they worked well Red/White band IIRC, they only do them for the rear, obviously because the police don't carry their kit on the bonnet....

You also continually seem to be ignoring the fact ARB's where also fitted, which as I stated several times also heavily impacts the roll stiffness of a vehicle. Which was the point we were discussing based on your somewhat stupid comment that a p38 is "unstable" when lifted above the normal ride height. Think about what you said.... "unstable". What is it going to do, flop onto its roof when parked up due to a stiff breeze

Just wanted to pick up on this point.EAS as said comes in to its own when towing offroad, it's a breeze compared to having a saggy arse, much like my D2 and old RRC nowt worse than having the arse dragging..
Yes the EAS is very good at self levelling the vehicle. As it is purposely designed to do this.
However, if as you say you were having a saggy arse on a D2 or RRC when towing, it sounds more like an incorrectly loaded trailed or overweight. I can't recall the correct figure, but the tow hitch will be rated for 75-150kg nose weight. Which should only induce around 1" of rear squat + -
If you are seeing lots more squat, which by the sounds you are based on your description. Then your trailer is massively nose heavy.

Think outside, no box required.
As I posted there was also a significant weight in the boot, I assume you didn't read that part..
anyone with a RRC will tell you that even a packet of peanuts on the backseat will cause it to start sagging...
I can only imagine you have never towed with a classic.

What are these then?

I'm assuming LR considered the P38 unstable at above 35mph in offroad mode, and it is common sense any lifted 4x4 is prone to falling over or at least becoming unstable at any high speed evasive maneuvers

That's a figment of your imagination 'enery,and he seems to think I said that the air spring constantly adjusts , something that I never did, unless he can prove me a liar by quoting he post number. Never let the truth get in the way of an argument.What are these then?

Seems an odd chap, I guess even though I provided the springs, i'll again be considered a "díck" because I posted evidence to my claim!That's a figment of your imagination 'enery,and he seems to think I said that the air spring constantly adjusts , something that I never did, unless he can prove me a liar by quoting he post number.

Oh well.

Why deal with it? I’m off road doing 5Mph! When on an ordinary road i am not cutting the limit so fine that the marginal change will make any difference and the over estimate built into the speedo will more than compensate. also, you get done for speeding at the limit plus 10% plus 2mph - and i’m not planning on testing that assertion!
