Evaluate my launch _ REVISED
Evaluate my launch _ REVISED Please rate my launch. Never mind I started the burnout with TCS on. Never mind that I forgot to take it out of 1st and got beat by a slower car. Never mind the shaky camera person. If you can get through all that, please evaluate and tell me what wrong you see.
Staged before launch.
Launching.
Weight still transferred nearing the 60' mark.
Weight still transferred way past the 60' mark.

You are getting very little weight transfer. If drag racing is your passion and you want to find that max ET, I would remove the front swaybar, and do front QA1 R shocks. Will make a big difference.
Front sway bar was removed about 6 months ago. I looks to me like there is a pretty good amount of weight transfer since the front shocks are fully extended and the front tiress are barely touching the ground in the 3rd pic. Take a closer look at the difference in the angle of the front of the car between the 1st and 2nd pics.
In the 1st pic, the angle of the car trim piece at the bottom of the door is pointing downward. In the following 3 pics, it's clearly pointing upward. Doesn't this mean the weight is transferring to the rear wheels? Not doubting ... just trying to figure out what else would indicate the weight is transferring or not. Because, between the 1st and 2nd pics, there's a big difference in the angle of the car when it's launched in pic #2.
I can't really do the front shocks just yet, financially. I'm thinking V6 firebird springs in the rear and weight off the front as a cheaper alternative until I can save a little more money to do the $$$$-type weight reduction.

Dang. I thought I'd check on here tonight and have some varied opinions ... kinda' disappointing nobody else responded. I'll post back up when I go racing tomorrow night and try for a better launch.
I have to agree you are getting very little weight transfer.I have the oposite problem mine is squatting too much

NOW I see what everyone is saying. Mine is transferring weight poorly. It looks like I just need to adjust air pressure and take off front weight until I can afford a good set of QA1 R shocks on all four corners. I'm going back out tonight while the weather is still cool.
In the pics above, I only had 17 psi in the MT DR's and I didn't hammer the pedal on that launch ... pulled a 1.61 60' time. I think tonight I can adjust tire pressure and get a pretty deep 1.5x 60'. And hopefully, will get better pics showing some better weight transfer on a hard launch.
I think my biggest problem with weight transfer (in the pics) was not having enough air in the rears to gain enough traction to be able to stomp the pedal off the line. I tried it the 2nd and 3rd runs and spun really bad. The track wasn't working very well for even the big slick cars, so, maybe the prep will be a little better tonight.
Thanks to everyone for helping out. I'm always open to suggestions.

Thanks everybody for responding. Didn't make it to the track tonight ... alternator died ... ended up breaking the volt gage wire inside the connector and had to disect the connector to put a 3" piece of wire in and solder it back to the one from the wiring harness. By the time I got it swapped out, it was too late to drive the 30 miles in traffic to get to the track. I'm disappointed and sorry I can't post any new results tonight.
I'll be there Friday and will post up ... once I get back with some new times. I know I will have some good times to report back on ... got some air in the rears now .... 17 psi was just way too low last Friday and the track wasn't working for a lot of folks. I should easily be 60 footing 1.5's. My ET should be below 11.5's ... driver mod almost there, though.

I was launching at about 1800 to 2000 ... psi too low ... just playing with tire pressure right now. Seems senseless to not start there. Friday night I'll try flashing the converter with about 22 psi to see what happens.
Damn fellows! Went back out Friday night and barely did any better. Several of you recommended raising the lower control arms and I realize now that is where the main problem is. I didn't realize the angle was SO FRIGGIN' STEEP!!! I looked under the car today and they're like steeper than I've ever seen on ANY car. I'm bringing them back down level tonight. My apologies for not listening and at least taking the time to look, previously. 
I now can plainly see the car hits hard and sticks like glue and only a few feet later, the suspension rebounds/unloads and then hits hard and sticks again. That's exactly what I have been feeling whenever I launch. Thanks for tolerating my being hard headed at times. All you help is greatly appreciated and I'm learning to open my ears and listen to the voice of experience.
MAAAAAAAAN, this is a great forum. Thanks to all who have continued to help me. I'll be bringing you back some decent 60' short times and a better ET for sure, soon.

Hey, I saw your car run ... had no idea it was you! ****!!!! lemme know next time you go out since I know your car now. Sorry I missed you. I moved the LCA's to the upper hole in the relo brackets and it feels like a more steady pull out on the street today, however, I can't really know until I get it out to the track and launch the f**ker.
You plan on going back out soon?
