Looking at your car with its design in mind, The A-pillars are the first line of defense and strength on a Hardtop aside from being the frame for the front windshield. The structural braces that run along the side and the cross dome light brace act as longitude support or spinal cord as they connect to your C-pillars where the roof line swoops down. All that area of the side windows (without a B-pillar)is just a big void where strength is non existent and could be at question when a car launches hard.
Contrary while looking at the quarter panel area on a Post Sedan, it pretty much is like a triangle of strength, with the Post door acting as a silent partner sought of speak.
But when a Hardtop comes into the discussion, it is an open horizontal V shape that is strengthen with the braces in the C-pillar and quarter window inner panels just behind the front of the quarters. The cross brace just behind the back seat gives the whole package some side load assist. The doors themselves are just a hanging panel that pretty much does nothing. The dome light cross brace is not too much of a concern but it helps the roof. If anything, I would go there with the Dremel tool.
Now if you cage the whole package, even with Chrome-moly, it pretty much puts back the same weight or more just to stiffen the car back to normal and make it safe. The cage in that case of course, stiffens the car, but then it is leaning towards becoming a chassis car.
I think that 30-40 pounds could be found on the front end still. You probably will not go with Carbon fenders or glass, but maybe some hard thinking will invent and desent the weight in another way.

Guess I`ll leave it alone then as safety is still a small concern and I`m jonesin to weigh it then go for a well overdue street thrashing.........

Excuse the prehistoric technology but I still have the 10.2 Factory Drum setup on all four corners. The Factory Drums are lighter than the Factory Disc brakes even though a friend of mine Special K disagrees. I used the drum assemblies shown below to save 1-1/2 Lbs from each drum over the Factory Finned type Drum assemblies. The finned types even though they may cool off better, carry a heavy surplus rotational wise. The plus side of drums is that you can back off the adjusters and free wheel them slightly at the track where as the Discs have a slight or heavy drag from the pads naturally. This practice is of course rather risky and only for the experienced drivers accustomed to their tracks. In my case, it is interesting when trying to slow the pup after the run though. not for the faint at heart.
Now of course, after market Discs the likes of Aero, Wilwood, Strange, etc. may be all together lighter than drums and not create much drag at all depending on the calipers and such. I have not heard much about that.
Keep in mind that there is a difference in mass and weight between 11" drums and the 10.2 drums.
Factory Strut rods and hardware are 6-1/4 Lbs for the pair, Aluminum non adjustable types like those available from Mancini are 3 Lbs a pair. Saves 3-1/4 lbs. I made my own strut rod coned washers out of aluminum though.
