The good news is that I found another spring after I realized the error that definitely does work. P/N 72577 at Century Spring is the winner 72577 - COMPRESSION SPRING - Part Characteristics | Century Spring Corp. The spring rate is roughly 20% of the stock spring and it feels very similar to running without the spring installed. The bad news is that you need to order 4 of them to meet their minimum order quantity.

Here are some pics of the Century spring


Stock is on the left, Century on the right

So just to confirm, P/N 72577 at Century Spring does work and fixes the spring problem? If that's the case I'd be willing to get in on a group buy with 3 other people if anyone is interested.
