P.S. I almost bought your F after you traded it in a while back.
Typically 12.0@high teens. I've actually gotten 120.xx just a handful of times and I've gotten 11.9xx just a handful of times - but those were PERFECT conditions. It's hard to get great DA here in Chicago.

Iv'e stopped drag racing lately because I don't have any mods that'll improve it at this point. If I ever do the seats or get skinnies up front, I might go back to the track again.

Makes no difference how you attach the hardware. You have nowhere to go when you have shoulder harnesses, so the roof crushes in and your spine gets shattered if you don't have at least a roll bar. No responsible racecar engineer would ever put a full harness in car without a roll bar. The OEM three point allows you to move sideways when the roof comes smashing in, so you at least have a chance.

What about a roll bar with a helmet

If you are getting aftermarket seat I would try to keep the stock seat belts

Which modifications have you done to your car?

I've dropped a bit over 185 lbs, while still being street-able and nothing extreme. There's still room to cut a bit more weight, before getting into the hard stuff.

See post #9, I'll be installing a Braille 21 lb battery today (battery hold down arrives!) next is going to be a lot of the under car fairings/ engine bay plastics, trunk mat (I don't put anything in the trunk as it is), when I install the giken diff I'll weigh it just for info here, I got Megan front upper arms that aren't installed yet but when I do I'll weigh them.

THIS JUST IN!: so I lost 12 lbs switching to the jic magic ti bullets (4 lbs each vs 10 lb each joes) and 22 lbs all together when I installed a 21 lb Braille battery and removed the side engine bay covers. I used the oem battery hold downs (used a 3/4" piece of plywood cut to the size of the battery) then moved the ground to the apron where another ground point was, along with that I moved the relay(?) in front of the fuse block.

It's secure, started right up, looks amazing! Only complain (not batteries fault I guess) is when you go to start the car the passenger windows don't go down. Is this a Lexus/Toyota techstream kinda fix?

No. Just initialize the windows one at a time with the switch on the appropriate door.

Turn on the ignition. Open all four doors. Raise and lower the window of each door with the switch on that door from top to bottom. All the switches on the driver's door will now work correctly. You also need to open and close your sun roof the same way to initialize it.

This has to be done anytime the battery voltage drops too low, or if the battery is disconnected. This is why I say it is stupid to disconnect the battery to reset the ECM when you can reset the ECM to factory defaults just by pulling two fuses.

I remember my first time experiencing this...about 3 years ago when my original battery died.

What is the minimum CCA required for our cars? I am looking for a light weight battery and did some searching on the corvette forums and it seems that 400 CCA is good enough for the vettes..
