If you have the resources, I would recomend making your own standoffs out of delrin. This way they could be a larger diameter and distribute the load better and still be lighter than aluminum standoffs.

If the delrin standoffs are threaded, they will be much lighter than aluminum overall, but the threads won't hold up real well.

If the they are thru holes, they bolt increases the weight a lot as it is rather long. I'd Imagine an aluminum standoff with tapped ends is lighter than a delrin standoff with a thru bolt of comparable strength,

That is a very good point. I have actually not thought about that before. One nice thing about a thru-bolt with a delrin spacer is that you could buy delrin round stock and make the spacers yourself saving a ton of money. We spent $150 just on standoffs for our drivetrain last year which used COTS threaded standoffs.

We should be able to buy raw stock and tap the standoffs ourselves, so that should be be much of a problem.
