first time i had the car at the track it a vq35 rev up motor on stock 350z rear tires 245s. slightly used brigstones. droped pressure to 12psi bout a 8 -10 sec burn out, hooked hard on the launch then "snap". the rear end has been up graded to 93 j30 lsd with the axle shafts. both outer and inner joint are ball and cage joints. the axle shaft snaped about a 1-2" in from the outer joint driver side. probble didnt help that i ran about 10 times in a hour

that vq is deffinetly puting down some torque.
