Aww but you could be the only race car with AC!
Why no AC? BECAUSERACECAR!!!
I can't wait to see videos of this beast ripping butt holes open on the track

Junior1 is swanky. He might need the AC. 
Since he's not quite finished, just wasn't sure he removed it yet and whether the weight was with or without it.

UPDATE * 10/9/2012 *
DONE
So after 10 months and approximately 240+ man hours, the car is now done
Aside from some fitment adjustments made today everything went smooth
The car is now home and ready for some shakedown. There is still a few things on my list to do but I am going to see what track time I can line up in the next couple of weeks.
The car is still loaded in the trailer and I should have some more pictures up tomorrow or the next day since its been raining.

Good luck Chris. Nice work. If Fischer and Buttermore can be winners, so can you!
Just don't sell used shocks...

For 2013 nasa is changing ST2 to 8.0 and dropping PTA/TTA for a new ST3 class with 9.0 and 9.5 for aero cars.

Yep lucky for me, the car is still loaded on the trailer...
ST2 is going to get faster. But actually if I read and did the math correct, I'm right at ST3 now without touching anything. May open another door for me, gonna wait and see what takes place
Agree, should be some nice car counts in ST3. I still have the CCW wheels if you need more tire.

OK Bill.
My guess is this was not only for car counts but coincides with the shakeup in SCCA's T1. Alot of the Vette's may move over and slot right into new ST2 now. At this point I think I can add HP and run under ST2 or make little to no changes and be dead on the ST3 ruleset...

Junior, what's your weight and horsepower? When calculating weight, do you include the weight of the driver and a full tank of gas?

Empty weight was 3366. "Competition Weight" includes driver/gas so I'm using 3566 and HP is 401.
Sedans get +.4 added and I have to add +.35 (for the weight over 3550). The Grand Am Conti's are not subject to the -.75 penalty

Good lord. Sounds like you're about 500 pounds lighter than stock. Based on your prior posts, I know that a lot of the modifications that you've done are non-starters for those of us who don't want to give up seats or functionality. Do you have any weight reduction recommendations that you consider low hanging fruit (either because the mod is cheap from a price/lb perspective or because it comes as a side effect of a different performance mod)?
Personally, I estimate that I've lost about 100 lbs: 26 for headers, 30 for the Magnaflow, 10 for the spare tire tub, about zero between the various gains and losses for the plentitude of mods in the engine bay, 5 per corner due to the Ground Control kit, wheels, and tires, 20 for the LS7 clutch and Fidanza flywheel--and then I borrowed back about 45 lbs for a good 10" subwoofer and multiple layers of acoustic cladding (damper+MLV) in the rear.

The biggest bang I think was the combination of Seats (stock ones are like 80lbs each, my Recaro's are 18lbs each), Clutch/Flywheel, and Windows (my Lexan is maybe 40lbs in total). Like you said though its a bit unforgiving for the street.
Aside from the clutch/flywheel, headers and exhaust that you already did. I know there are some gains to be had with the battery (easily 20lbs), 2 piece rotors and the TD Wheels. (you already have aftermarket) But the 18" are lighter than 19". Not sure about the coilovers but there could be some there as well.
The removal of all the A/C stuff, Airbags, and interior trim really adds up after a while. But its just that its a nogo on a daily driver...
Are you at 401 whp? What mods have you done? I only saw the initial post about engine mods.
