My best times with SRT, T/C, TRD LSD and my stock 16" All-season tires, haha, was a 14.49 @ 96.76 with a 60 ft time of 2.17. I also ran a 14.5 and 14.6. These were all on the east coast here in 50 degree weather in early spring. And I just hammered the accelerator too, didn't try power-braking the car, would suspect I could of gotten a 14.3X perhaps, who knows. Maybe one of these days I'll hit up the drag strip again and see what I can get on my 18's. I would suspect slower times though Regardless, FI is needed to get these sedans into the sub 14-sec 1/4 mile consistently.

BA, congrats nice to see more Lexus owners at the track. Your times are better than most.

Each time I went to the track I went quicker and faster.

My first time (with the 99, around my 50th time overall) the best I could manage was:
Air temp 85 degrees
60' - 2.236
330' - 6.329
1/8th- 9.664@73.93
1/4 - 14.933@94.14

Next time it was slightly cooler at 83 degrees
60' - 2.241
330' - 6.315
1/8th- 9.616@74.77
1/4 - 14.823@95.33

Next time it was 77 degrees
60' - 2.245
330' - 6.244
1/8th- 9.509@75.35
1/4 - 14.691@95.50

Next time it was 73 degrees
60' - 2.229
330' - 6.222
1/8th- 9.468@76.00
1/4 - 14.577@97.29

Last and BEST... air was PERFECT... 43 degrees, 30.4in/hg
60' - 2.201
330' - 6.068
1/8th- 9.230@77.95
1/4 - 14.223@99.38

Notice a pattern?

My best 60ft has been a 2.196

This was on stock Bridgestone RE33 225/60-16s
Brake torque to about 1800rpm and roll on gas to avoid wheelspin. TC off, tranny in D.
All runs at Houston Raceway Park in Baytown Texas, very nearly sea level.

Not too shabby for an LS400...

I would say just keep practicing in stock form with lots of practice I came out with a 14.49 click on my link to see the time slip. Jbrady is right it takes practice with the GS4, my first time at the track I ran a 15.6..LOL but got better thur the night. I plan on hitting the track this Friday so If anyone wants to roll from the DC area let me know.
