As posted in the other thread... you can only remove the glass if you have to to install the door bars.
In Improved Touring if it doesn't say you can then you can't... The entire section that allowed you to remove door window glass, window operating mechanism, inner door trim panel, armrest, map pockets, and inside door latch/lock operating mechanism was deleted from the ITCS thus you cant remove any of it... Unless however it is to facilitate the instalation of side protection bars as stated in the "new" rules:
9.4. ROLL CAGES FOR GT AND PRODUCTION BASED CARS
D. SIDE PROTECTION
Two side tubes connecting the front and rear hoops across both door openings are mandatory. NASCAR-style side protection or one bar bisecting another to form an “X” is permitted. Door side tubes may extend into the door. In American Sedan, Improved Touring, Showroom Stock, Spec Miata, and Touring the door window glass, window operating mechanism, inner door trim panel, armrest, map pockets, and inside door latch/lock operating mechanism may be removed and the inner door structural panel may be modified, but not removed to facilitate this type of side protection. The stock side impact beam and the outside door latch/lock operating mechanism shall not be removed or modified unless specifically authorized in the category rules.
Thats how I read it however... if you were to end the sentance before the "and" then you do get...
