I went to the 1/4 mile track the other night. Here are some videos, sorry they are on facebook, they aren't my vids.

I had a few questions though. First, kinda odd but, when I get on the throttle hard and let off the Yaw angle of the car seems to change more than what is comfortable. What could this be? It happened on the street the other day in 4th and I thought I ran over a cardboard box or sand on the road or something. It kinda feels like the right rear tire looses traction for a moment, but I don't see that happening at 80+mph.

Second, after just one run the transmission became quite hard to shift. I have never had any problems with syncros or anything. It is was just very stiff. I changed to some royal purple tranny fluid a while back(<15K miles), so that shouldn't be bad or anything. Any ideas on what it could be or how to rectify this?

Third, F... it is hard to get a good run in this car. The throttle seems to want full on or full off, when I tried to feather the throttle, I just got jerked around and my glove box flung open. I should have had a camera in the car it would be funny to watch one of those runs later. I got jerked around, the Camaro flew by me, the glove box flew open, I hit boost cut a few times, then I stuck it in 4th, the shift knob came off and I caught back about 6 car lengths on the 'maro.

Here were my times:
I ran (in order):
12.75 @124.6
14.2@115.7
12.9@123.5

My problem: 60' times ranged from 2.28 to 2.37

Sounds like it could be RTABs, subframe bushings or diff mounts. Climb under your car and check all your bushings. Stock E36 M3 is capable of 2.0 60' times on all seasons.

Thanks, I'll look into that. Yeah, I've pulled <2.0 60' times in this car when it was stock (not turbo) on harder tires. But, it seems to be another learning curve with 500hp and the type of power delivery I am getting.

I found one more video:

Wow! You have so much more left w/ a 125mph trap speed. But, I don't understand about the full throttle problem.
