Please Help With My 60'

Took my car to the track last night and was disappointed with my time. I had no traction atleast the first 60'. I also broke two of the tranny crossmember bolts (on the same side) so I only made 1 run.

My engine setup is in the sig. Here is what I have for suspension. Spohn LCA's and panhard with poly bushings, stock torque arms, Eibach springs, Koni 12 way adjustable shocks, 3.54 gears. I was running on my BFG G-Forces with about 28lbs pressure.

Here's my timeslip:

R/T: .105
60':2.159
330:5.932
1/8: 9.062
MPH: 78.35
1000: 11.760
1/4: 14.025
MPH: 97.81

My second run I would have tried dropping tire pressure to 18lbs to see if it helped a lot. I know slicks would be a huge help, but I don't want to bring out any other weak points in the car yet...that'll be one of my last steps probably.

I need some more computer tuning, but my 1/4 should probably be almost a second faster.

I am open to ANY suggestions you guys have.

Throttle control Don't just stab the gas expecting it to dead hook on the track, quickly roll into it. I shaved off half a second on the 60' by doing that when I ran at the track for the very first time.

Good point....if I get more than 1 run next time I'll try it.
