Since the washers are completely independent, I think it would stress the studs too much. They can shift and bend on each stud where one piece with holes in it would try to shift on all 5 at once. I think they'd be fine for seeing what it would look like without driving, though.

One thing you can try is buying several thin disks. I've seen several for about $12 each that fit Boxsters and are 4mm-5mm thick. Just for the look, you can put them on with the original studs and see what it looks like at different depths. You would have to get new studs long enough to hold the spacers before you could actually mount them and use them.

There are also "adapters" that are much easier to install since you don't have to remove the studs to do it. They bolt on to the original studs and have their own studs built in for mounting the tire. They are a solid piece rather than several stacked disks. They tend to be less expensive too.
