At what point is a torque arm that doesn't mount to the tranny needed?

I figure I am going to purchase a new torque arm before I swap my stock rear for the new 12 bolt. I'm not sure if I need to buy a torque arm that relocates the mounting point or if a tranny mounted adj. torque arm will surfice. I have yet to be to the track so I do not know what the car runs as I am worried about breaking something so I am waiting until I have everything I need installed. Here is a general description of whats in the car...

1994 Z28
Lt1 stroked 383
Vortech Supercharger 10lbs
SLP headers
4" mufflex
12 bolt moser
carbon fiber DS
strut tower brace
subframes w/extra supports added
G-load brace
panhard bar
LCAs w/relocation brackets
6point roll cage
etc...

Thanks
Mike

 

whatever you are going to do, hurry up, I want to see some numbers on a 383 super charged. I am still in the dreaming stage right now, because I need to graduate high school before I dump thousands into my car. If you can hook up, I can't even imagine numbers on that car. You should hook up a 150 shot for one run and see what you can pull, if you dont blow anything up.

 

Dont know about the 4th Gens, but in my 3rd Gen. I run 10.40s @ 128 with 1.40 60ft times. The only problems I have with the STOCK T/A is breaking the tranny mount. With that being said, I would say that if your gonna by an aftermarket arm any ways, I would get one that relocates the mounting point.
