Is there a market out there for stock 380vrx springs or should i throw them out???

To common. second hand they would hold a value of like $20

Wouldn't be a market on here, but you could always give them a go on Gumtree.

I would re-iterate that they would be a great upgrade for someone who had purchased a base model.

How many kms? Unless they are low then there isn't much you can sell them for.
