F-body short trailing arms, Pete Z bars and etc...

1slowformula · 12-20-2007, 09:51 PM

Hey all I am new here and not really sure where to post things. I have been looking for info on these types of short trailing arms for the late model f-body on a few of the boards related to them in general, and a couple guys pointed me this way stating that the super stock guys run them and would have more details. I have search this forum and haven't found much on them other then there is another guy here doing similar bars, Joe Russell...

My biggest question is how reliable are they and can you complete do without the torque arm when using them? I have read many things where it is recommended to run the torque arm as a "just in case" measure if something may break, but over the years I have not heard of anyone breraking anything...

Any feedback on these types of bars would be helpful, thanks.

I have a set and will be running the torque arm also. I 'd like to know some more about them too. We'll see in the spring how they work on my car.

I tried once leaving the torque arm off, against Pete Z's advice. Should have listened. Wheel hopped so bad I broke a sprag in the tranny. He says to let the front "float", makes all the difference being on there.

We are actually building a SWING ARM car with our 2002 camaro with the LS2 for Super Stock. It incorporates the torque arm but we added another side. We extended it further than I have seen any other torque arm extend in the chassis. Its like a four link set up with all the numbers done for you through the location of the arms. The best part is we didnt have to hack the car apart and worry about the chassis not passing. And any tire clearence is easy as we have done it in the pass with customers cars and made 8:80 passes on a true 10.5 tire. We are using the trailing arms, but I can say we did the geometry to make it work and the length of the trailing arm is VERY IMPORTANT!!!! With the engine placement in these cars, they already have no problems bring up the front end. In fact, we worked to slow it down so they would not be so violent on a hard launch.
