I am curious if I should remove the wheels while the car is on jack stands for a few days? Just wondering if the weight of the wheels would put too much stress on the suspension while the car is on jack stands. Thanks.
I think you are fine. The NSX suspension doesn't really have any points that could be stressed by the weight of the wheels and tires. I guess you could look at the control arm bushings and check the ball joints, but I'm sure they are fine.Um, what would need to be checked if the car sat on jack stands for most of the winter storage while you were changing the steering rack, the coolant, engine oil and a bunch of other things? Asking for a friend.
I think the issue is flat-spotting the tires or causing balancing issues, not suspension damage. The original Yokohama A0-22 tires were very soft, like 100 treadwear.FWIW, page 226 of my 2001 NSX Owner's Manual states this in the section on storing greater than 1 month:
"If the car is to be stored for a longer period, it should be supported on jackstands so the tires are off the ground."
It also calls for starting the car and running the engine for a "while" monthly. I thought that advice had been dropped.
Makes sense, but it would suggest that the suspension can take sitting on jack stands for a few months without damage. There's no mention of removing the wheels to reduce the static load while sitting on stands.I think the issue is flat-spotting the tires or causing balancing issues, not suspension damage.

I think the concern was having the suspension at full travel for that long of a time. If you're just getting into working on your car, and you don't have a lot of experience with the very complex suspension of the NSX I think it's a valid question.Is this what people are asking on forums these days?
Trapped, but based on how the control arms articulate, I'm not sure there is much of a twisting moment on them.Are the upper rear control arm bushings trapped or free to pivot? I have never got up close and personal with them; but, they kind of look like they are trapped (molded in place). If that is the case, having the suspension in the full dropped position applies twist to the rubber which moves if far from its normal happy place. On an aged bushing that may result in tearing in not so flexible rubber. If the bushing is free to pivot on the mounting point then twist is not an issue.
