my 1/4" SHEILDS brand polycarbonate is 10
it's an expensive 17 lb weight loss but everything counts when you don't have to hit a spec weight

Turns out my weight was optimized for GTB as opposed to NASA GTS-4. I got it on the scales and with a little under 1/4 tank of gas and an empty cool box I was 3009 lbs. The gas will offset the fact that I almost always race with a cool box so that's my current racing weight. Still have weight to drop, even in GTB and my NASA weight is all the way down at 2,763! (Dyno'ed at 307 rwhp)
Heater box still has to come out, but after that additional weight saving will be tough. Not sure if the charcoal cannister is still in place. Also looking at fiberglass front fenders and pulling the headlights for when I run with NASA. Not sure about the Lexan screen yet, not sure its worth it. Any idea how much weight is saved there? I was looking at the MA Shaw hardened version. What did you go with?
You are right about the GTB rules, some cars are theoretically more equal than others.

I don't understand why you're car's weighs 3,000. w/driver. IIRC you're about my size (165?), so your car weighs about 2820 empty. The 99'-01' cars are 50 lbs, lighter than yours, and I'm at 2620 empty. Adding that 50 lbs back and 30 for the heater core and I'm still 120lbs. less than you with all steel body parts and full glass. Something doesn't compute here. Is there some lead hiding in there? Jimmy Hoffa in the trunk. IIRC I think Carlooz weighs around 2735 empty, correct Carlos?

wipers removed.
no brace needed with 1/4" thick polycarb. you could go with thinner material to get a lighter windshield, just make sure the brace is light enough as to not offset the weight savings.

Tomorrow is Spec Boxster day at the track but T-giving weekend I'll have time to get all the cars back on the scales and see if something was messed up the first time I weighed it. Will report back then ...

MOSPORT. Most thrilling/scary track I've ever raced for the 1st time (other than the NurburgRing).
Looking forward to the PCA race at Mosport; I know I left a full second to go faster; just need to wear tighter underwear to keep the required bigger attachments in place!
