Best 60ft with Vig3200 and 3.23's? I couldn't do better than a 1.69 last week. Stock 3.23 gears, mods in sig. Tires wouldn't even chirp, dead hook each and every time. I had about 5 1.70's, a 1.69 and a 1.71. The DA was around +1900. Raceweight was 3670lbs with me in it.
I tried experimenting with the launch but wasn't sure exactly how far I could stall it up without the tires breaking loose. I went as high as 2200rpm with no difference in 60ft, ET or mph.

I should be able to, I didn't really try experimenting until my last two runs. Since the actuall stall speed is 3800, I can't see why I wouldn't be able to bring it up to 3K or possibly a tad more. I had heard people saw late 1.5's with this converter (with bigger gears and reduced weight though).

right... but its hard to watch the light and the rpms without a large tach

If you are not breaking the tires loose, with your particular combination, you are running the "best possible" 60 foot ET. Change your take off procedure, and "see" what the changes do, before you make rear end gear ratio changes, torque converter stall changes, etc.

I'm not sure what the breaking point may be. It's kinda tricky because there is no prep on the street where I could just do a practice launch, they'll just go up in smoke.
On another note, I didn't think a higher DA could affect the launch because the car hasn't really started moving much distance. I'll try experimenting again when we get a cooler day around here. One good thing (which I hated) about the Nitto's is that you would rarely get a dead hook, the car actually felt stronger off the line because you'd shoot right up to redline faster. These tires make it feel like my car is bogging (on a sticky track).

sounds like to me you have too much tire for the car... those MT Drs in the 17 are very heavy and pretty tall for your car...

youll get it.. just keep at it.
