Double Bass Spirocore Users Please Help.

This is your fingerboard, and likely your setup in general. Right now, I've got a set on that's sitting at 6mm on the G and 9mm on the E. What sounds strange about your string heights is that your bridge is cut in a way that doesn't allow for greater clearance on the lower strings. Normally the measurement for the E is greater than the measurement for the G by a couple of mm or more. At any rate, 8mm should be plenty of clearance for the G string with Red Spiros. Sounds like you're due for a fingerboard dressing. Know a good luthier?
 
From the information in your post, it sounds like you need to get the fingerboard planed. The length of the upright bass fingerboard is not flat; there is a slight hollow or "camber" in the board. Some new, lower priced basses have no camber. Some are even convex, which makes playing damn near impossible.

In addition, wood shrinks and swells witht the seasons, and from time to time the fingerboard needs to be planed to get it back to an even, lightly hollowed surface.

Hope this helps.
 
What a relief! Took Him four hours to finish the job. But result is Great. I love my bass again. What a great Guy didn’t even charged me at all... (I bout this bass 3 months ago from that store) Now my action is about 7-9 mm. He only dressed G and D parts of a fingerboard; mostly G .The neck was almost flat, so He deepened it 1mm or less. So far, I am Happy.
