When german car magazine Sportauto does a test they do it thorough 
Here are the results regarding drag and downforce:
New 911 GT3RS:
Drag (cw): 0,33
Downforce at 200 km/h (124 mph): Rear 49kg, Front 11kg
New 911 GT3:
Drag (cw): 0,32 (because of smaller spoiler and tires than RS)
Downforce at 200km/h: Rear 19kg, Front 15kg
Old 911 GT3RS:
Drag (cw): 0,30
Downforce at 200km/h: Rear 10kg, Front -2kg (as in 2 kg lighter)
Old 911 GT3:
Drag (cw): 0,29
Downforce at 200km/h: Completely neutral at rear and front.

Honestly, if this car is going to be used in DE events or just regular tracking, I don't really see the need for more downforce. If you really want a track only GT3, I'd focus on suspension setup (consider contacting RSS, TPC, or Champion) and seat/harnesses, which you seem to be covering.

Based on downforce post above, the RS is 2.5 times better in the rear? That sure is good for corners and confidence. We all know that times are made by settup up the corner at the start with good speed thru and coming out.

Tbh I'm not sure how much of an advantage that is. It's not like it has 2,5 times more weight on its rear, only 30 kg more. And 30 kg compared to the total weight on the rear due to the cars weight probably isn't much more than 3-4%.

Can't say I agree. While it might be that at rest, at motion and turning, the weight becomes less vertical and more horizontal. I believe the downforce becomes exponentially more important as that transfer begins to happen.

Nice car, excellent upgrades!
I have spent time on track in all variations of the GT3. I have never had a downforce issue with the standard wing. I recommendation is to slap a .1 RS wing on a GT3.1.
Good luck and maybe see you at the track!
