Its a 7.5 out of trans am with the worm gear style pos that gm also calls trutrac and it was out of a stick car. only issue is if it comes out of burnout sideways it kicks out and u have to do dry hop to re engage it or it will blow one wheel. Still after all the horror stories about a 7.5 i went out in truestreet n had a decent 10 sec average on spray with one. Low buck driver with air that runs 10s, gotta love it.

1.50-1.52 short times here barely spinning.. 3500ish # race weight. Has GM 373s and a TA girdle. I don't see it breaking any time soon.

Not unheard of by any means with an A4.
