Question Coilovers: where's the sweet spot?

I've been thinking about getting coilovers for the Scooby and I already have H&R coilovers on the Audi and I got to thinking:

Even though coilovers are height adjustable, they adjust the lower spring perch only. Therefore when you adjust the height, you're changing the static location of the piston in the strut. So, there will always be an "ideal" height from a performance standpoint, which is where there is equal (or some other ideal proportion) travel up and down. Any adjustment up or down takes the shock out of it's ideal range, much like putting lowering springs on a non-height-adjustable strut.

I guess this is why you have ridiculous situations such as DMS Golds not being able to run at stock ride height.

Now if you could actually adjust the rod length, effectively raising (or lowering) the whole strut assembly including the piston, as well as adjusting the lower spring seat, wouldn't that be much better? You would have a TRUE height adjustable suspension. Are there any coilovers that have this feature?

Or am I nuts.

You have to take into account that some struts are valved with linear dampening charactistics while others are valved for progressive dampening characteristics...

I really doubt you're going to care all that much unless you've got the car dumped which is stupid anyway or you've got it raised up for doing rally-x or whatever... in fact I don't even know that you have a problem when you raise them so take that for what it's worth

OK, let's say you've got six good inches of travel without getting too close to topping out or bottoming out. Then you try to run stock ride height on coilovers optimized for 1.5" lower. So now you've only got 1.5" of "up" travel. What happens when you go over a rise? Not good! Topping out a strut is a no-no, just like bottoming it is. The wheel lifts off the ground, you hear a clunk, and all of a sudden you're dealing with air, when it should have just been a gentle crest.

This is my point. "Height adjustable" is a myth. You can tune and corner weight with 1/2" either way, but you'd be stupid to run at either extreme.

I'm realizing now that the answer is to call Dave Clark and tell him what ride height you want and give him your credit card number. Who cares about the rest when you can order exactly what you need?
