Last minute things to drop ET is there any last minute things i can do to my car to drop my ET? its a bolt on lt1 and im taking it to the track this weekend to see what it will do. i want to try an make it a little quicker if i can but idk what else i can do within 2 days
More or less what MM said, remove ALL loose weight. Could be change, garbage, CD's, instruction manuals, Floor Mats, Visors, even seats. Also empty out the windshield washer fluid and most of the coolant overflow.
Depending on how crazy you want to get you can find a tenth or 2. OR go borrow a set of Skinny fronts with a street tire on it. Will drive fine down the track.

Inflate the front tires to maximum safe pressure. Run as much pressure in the rear tires as you can and still get traction. Tweak the timing for maximum HP at the track if you have that ability and test slightly leaning it out if you have the ability. Pull off the front sway bar and take anything out of the car that you can.
great pointers so far - a few more...
be sure to run in "the groove" make sure your tires stay on the beaten path where all the rubber has been laid down to hook better.
look to the end of the track middle of your lane as you pull up to stage to make sure you are pointed to the end goal and after the launch refocus on the end of the track, all this keeps steering corrections to a minimum , the quickest way to the end is the most direct way. usually the quickest passes felt like you didnt have to do much , uneventful
make sure you stay in the throttle all the way through the traps - dont lift until you are beyond the et/mph sign , depending on your gearing/setup you may benefit from holding a gear rather than shifting right at the traps if you can keep it off the limiter
less passes can equal lower et's - cool the car properly between passes and run the car only enough to advance in the staging lanes , if the car is parked in the pits hood should be up and if possible facing into any wind to scoop that cooling air in

Remove the air filter.
Run 93 octane.
Unhook the battery for 30 minutes and let it re-learn while it is on the 93. If you run **** gas it may be pulling timing right now.
Drive into the converter on the launch, ie pre-load it. Mash the brakes hard and step on the gas to get the rpm's up before you launch. This won't work at all if you are running crappy street tires, but if you are on drag radials it will help a lot.
I see you have a cutout, just remove your cat-back since it weighs around 35-40lbs.
I can find an honest 100lbs to take out in under an hour on a stock f-bod.
