Default coilovers= ride height adjustability?

I know some of the more expensive coilover system are dual adjustable and you can change your ride height.

I am curious how much of a difference it would make on ride height between one extreme setting to another.

If one were to have a front fascia that is fairly low like a greenwood kit, I was wondering if you could technically have the ride height set a little higher for street use and then "slam it" so to speak when you went to the track to autocross.

Anybody who owns coilovers care to chime in?

It's not a setting like on the shocks. There's a thread on the body, and you put it where you want depending on the springs. Ride height adjusts spring pre-load

Wow, those are some great pictures!

Looks like you can adjust it quite a bit! It almost looks like its ready to go offroading in that second picture!

Do you have a guestimate of what the difference in ride height would be between the first and second picture? Looks like it could be as much as 3" or so but then again its hard to tell just from pictures.

Beautiful car by the way!

Yeah, you've probably got a good 3" of range for the spring adjustment.

I like riding on the coilovers

3in from one extreme to the other in my case.

But it depends on the springs, but also the shocks.

They come with different length shafts and travel on them.

You want them pretty close to the middle of the travel so the bump and rebound are the same.

The other way I adjusted them as different thickness mounts at the top.
As well as offset mounts to the rear uprights, but that was more to clear the rodends

A good coilover will NOT adjust pre-load when adjusting ride height. Maybe not possble with the C4 setup though.

http://youtu.be/aoi6sMuDc04 Here is a video right after we installed the kit; had the fronts perfect and hand to adjust the rear after the ride. Once the ride hight was right I would never go back to a leafspring agian.

Right, but you need adjustment on both the top and bottom perches, I haven't seen a C4 coilover setup with an adjustable top perch.

What exactly makes you say this? is it that much more comfortable of a ride than the leaf springs?

is the ability to take corners at higher speed that much more appearant?

Just curious as to what the major difference was that made you never want to go back. There is no wrong answer. Im just trying to learn as much about them as i can

I put coil over shocks on my 86 and ride is 110 0/0 better. You ask about cornering I'm not a rode and track guy but it feels great on the street.
