car looks great! I too hear you about the weather - I had a 3-day weekend (we work 9hr days so every other Fri is off) and the weather was awesome here in Colorado so I worked on the race car quite a bit as well. It has been months of walking into the garage, letting the cold set in within 2 minutes, then just walking back into the house
I wouldn't lower the car IMO if it is mostly a streeter. I think it looks great right where it is at with a little rubber showing at the fender - it actually looks like a muscle car, as it should be. I would only lower if road racing it a lot and needing a lower cg or to correct geometry issues. Lowering may in fact screw up geometry thru motion... that would have to be verified of course.
Maybe lower it in the front for a little rake (I am partial to the old-skool hot rod rake that I grew up with on muscle cars). Get a bit of the look that started it all
