Isn't this insane? I'm on this section looking for tips and tricks on launching and to see if anyone else is experiencing this. I've been cursing Michelin's name since I bought this car and was just about ready to junk these tires at 2,000 miles out of frustration.

I actually tried launching in second tonite just to see how it was and it still spun! Granted, this was just on a local road, chilly night, no prepping anything, etc. But that's still ridiculous.

And the launch control is a joke.

I dug out my Dragy tonite just out of curiousity (again, local roads, full tire pressure, chilly night)...

12.36 @ 115.71
12.37 @ 116.06
12.44 @ 115.86

I have an AA catted DP and Armytrix cat-back. No tune. This car will run 11.9 with traction. I'm too ashamed to take this car to an actual track. Hard to believe my two cars before this were a 6MT R8 and a 6M Evora 400, and the car I can't launch is an automatic Supra. :thumbsdown:
What psi are the tires?

Good question. Since the car is only 3 weeks old, I assumed the tire pressures were correct. I didn't look on the night I did the dragy runs, but it's behaved the same way since I bought it.

I checked yesterday and they were 39 psi cold and got up to 41 psi while driving.
