First time out with MT DRs 275/40/17.
First pass was breaking up in 3rd maybe from the 90mi + drive to the track next two passes car ran fine.
3rd pass was a bracket race and I broke out in more ways then one.I knew the 60 was good so I couldn't bring my self to lift.
Also race wt 3250 and granny shifting.
More details in sig and video.

Thanks. Ya slipping the clutch at like 3-4000rpms and thay were holding great. 3rd pass not so much clutch slip and went to the floor sooner.
I think it still has more with better weather and if I can get a little more 60 out of those tires.
Also that track seems to be 1-2ths slower then Etown NJ my 03 MACH1 went
2ths faster at Etown with simler weather.

Wow! That is the launch I am looking for!

I am also using 17" mt's and for the life of me I can't hook worth sh&^. My buds are trying to tell me to go 15" with fatter side walls but I won't:)

I am trapping 117 also but I run a constant 12-12.2 w/ 60ft times of 2.2 to 2.0.

Can I ask how you car sits? How far is the ground from the bottom of you front and rear fender? I think this is my problem. My front is sitting 2" lower than my rear.

I aslo have to put less psi on my right tire than my left one or else the right just goes bye bye.

I can belive you can launch at 4-5k. Although my car is boosted, launching above 2500 is like doing a second burn out.

Please let me know have you car sits it would be much appreciated!

Oh great info!

Mine is sitting 25in front and 27in rear. I have full coilovers so I can adjust everything. I am running 255/40's in the front and 275/40 rear.

I am making 500+ on my street tune, this is what I have been running at the track also. My race tune is rediculous and now way would I be able to launch.

I am also running 31 splines and traclock. 3.08's in the rear. Boost comes in at 2500rpm and all hell breaks loose if my foot goes all the way down. I am not running any electronics at all (2 step).

15psi then go up from there?

Thanksssssssss for the info man!
