Winter storage question

Hey gang,
excuse the newbie question - 1st winter for me. Should I put blocks under jack points so car doesn’t sit so low on the left side? ABC is on the way out.

Beautiful car!!!!! If it were my car, I would be inclined to do so. But I'm not entirely sure. I don't think it will hurt the car at all though. I'm sure some other friends on here will know a little more, and chime in.

The front of our car sags if it sits for an extended period of time. So far it goes back to normal after starting when we push the "vehicle level control switch" button on the consul.

How long has it been sitting?

On our 2003 it seems to sag after sitting after more than a couple weeks. It seems fine if driven regularly.

There are o-ring seals on the valves in the valve block that over time wear out a bit and allow hydraulic fluid to seep past, causing the car to settle. As long as the car returns to normal ride height when starting up again (and maybe putting it in gear), you should be fine. If it becomes more pronounced, such as settling after only a few hours, you may want to replace the o-ring seals. Note that you can only "repair" the older valve blocks. A 2003 model should have the older valve blocks unless they have already been replaced with the newer version. But the newer version was supposed to have fixed this problem.

Lots of YouTube videos on how to do this.

You can find the kits nearly everywhere now when back in the day there was only one guy making them and selling them on eBay.

from the manual: if it sags after a day you might have an issue. If it sags after a week or more, normal. (paraphrased)

It sits like this after about a week - but it does sag pretty quickly and I’m going to do the Coilover Conversion in the new year.
