Can you help me figure out how to adjust height on these coilovers? [pic]

I recently bought this 99 Miata, the previous owner has it really low and I'd like to raise it a bit, can you help me figure out how to raise the ride height on this specific set of coilovers? Thanks in advance.

You adjust the blue nuts at the bottom of the springs upward (compressing the spring more). This will raise your ride height.
