Is it ok to open the door if the car is jacked up also does it matter if the top is up or down if the car is jacked up

 

I've never had any issues opening doors on my cars whilst jacket up. They sometimes feel as though they catch a little as the body is twisted, but I've not known it to cause any issues.

 

As long as you're using a jack stand I do it all the time. Never trust a jack, especially the OE screw jack. Always use jack stands and on flat ground

 

On some older cars, really older cars, the chassis could be so mushy that if one side of car was jacked up, opening door could cause problems, allowing chassis to flex more. Door might not close again until car was level again.

This isn't a problem with modern cars, and certainly not with a car with as stiff a chassis as the S.

 

Yeah my friend told me not to open the door for some reason I really felt like what he was saying made no sense

 

FWIW I would open the doors on my NB Miata without issue and that chassis is a floppy noodle compared with the S. Yes the door would seem to drag a bit but everything returned to normal when the car was back down on the ground.

 

You can definitely tell when the car is on jacks from the feel and sound of the doors being closed, so some flex occurs. Not an issue, but I always recommend people to unlatch their hardtops any time they lift the vehicle on jacks and jackstands as the body does flex and it can throw the hardtop out of adjustment a tiny bit.

 

you respond definitively at times to someone's nuanced technical question as if you know the answer but yet you will ask silly questions like this.

 

I never owned a convertible

 

But I know a lot about the technical stuff
