Time taken to completely collapse your suspension.

The Rough-as-nuts BX 19 DTR I picked up a few days ago has been parked on my drive since it was collected, and not been run. When I parked it, I left it in "high" wondering how long it would take to go down.

The front suspension has only just now finally got down to it's bump stops... it's taken a good 3 days to do this. The rear, however, is still up in the air, and has only just come off it's top bump stops.

It is undoubtedly the longest I have ever seen a BX (in fact any non-anti-sink car) stay up for. How long does your BX take to sink?

When cold (i.e stopped after a short journey from being started from cold) a matter of minutes. After that anywhere between 20 minutes to about an hour and a half but seems to vary wildly.

David, are we talking about sinking from high or normal position?

Mark.

I agree with Sleepy. My old hurricane never used to sink at the front (well for at least a week) although the back would sink completely in an hour.

EXCEPT if it was really really hot. Then the front would sink after a few hours.

The 4x4 sinks at the back after a couple of hours and then the front a couple of hours later.

The front stops about an inch short rock bottom until you give it a gentle nudge....

From normal position, as I'm sure that's what most people experience.

Normally, of course, the sink time from max is somewhat longer than from normal (maybe twice as long?) but from what people have said, it appears that ambient and fluid temperatures have a lot more to do with the time to sink rather than the initial height.

The DIGIT, for comparison (which I have never been able to drive more than 2 miles at a time) sinks fairly evenly, after about an hour from normal height, and about 2-3 from max.

From max both my hurricane and 4x4 will stay up for days.

The weather makes a big difference. Now its cold I think it sinks faster and takes longer to get up again. Does the temperature make a big difference to the BX and LHM? Odd. My 16v is abit of a trick though as it will appear to stay up for ages but rock the car a tiny bit and after the creaking has stopped it will have dropped by and inch or so! (or more!)

Thats the same as me then weather dependant and take ages to get up again and a little rock and I fall down with some creaking and cracking.

Amazing.... 10 days it's taken for the rear to completely sit down on it's bump stops.

Are you sure the rear arm bearings are good?

There's a little lean on the arms, but the suspension still moves up and down smoothly... It really has taken 10 days for the hydraulic pressure to leak away.

Must be the best combination of rear cylinders, Height corrector and Dosieur valve ever!
