The tranny does a poor job of handling the stress of keeping the rear in place. Transmission mounts frequently break on these cars as a result of the pressure from the torque arm, and occasionally I hear of someone breaking or cracking the transmission tailshaft.
We have found the BMR trak pak shown here for the majority of the cars.

For the serious dragstrip cars we recommend the Xtreme torque arm from BMR.

Here are pic's of what can happen to the factory torque arm, which is why I recommend replacing it. Bobhttp://www.exoticperformanceplus.com/services.php?service=58

I have a couple of questions..... 1.) Will the BMR Trak Pak work with the Moser 9" i'm installing soon? 2.) What kind of "additional road noise" are you talking about with the use of the BMR Trak Pak?

I like the tranny mount. Had a tunnel mount and hated it. Clunking when you shift gears and gear whine from the 12 bolt was amplified due to the torque arm mounting to the floor. If you go tranny mount you can always relocate it to the tranny crossmember now.

I have the BMR Trak Pak and it is awesome. You feel a lil bit of drivetrain vibration, but its the same as going with a PBH and LCA's type vibration. A good one, not bad. A tad bit noisier, nothing 1-2 clicks higher on the radio can't cure.

The only thing some gripe about is the clunking. It is the arm being loaded and unloaded. It is a very low clunk at random times, when you get on the gas. Nothing major. I have gotten used to it.

**Correction**

I actually have the BMR Trac bar with the UMI tunnel mounting brace.

I personally don't care for tunnel mount arms due to where they are attached. That's some flimsy looking sheet metal right there...

I went for a tranny mount (UMI adjustable), and if I ever get serious at the track, I'll throw on a new transmission crossmember that gets the mount off of the tailshaft. Lots of great options out there these days...

The "Trak Pak" will work fine with the Moser 9". The additional road noise comes from the torque arm being solid mounted to the subframe connectors. The additional noise (in my opinion) is minimal but if you are concerned about the noise I would recommend going to the full length style arm like a TA001 and use one of our torque arm relocation brackets to take the load off the transmission tail shaft. I have several customers running well in to the 9's with this style setup.

If you have any other questions regarding our product line please feel free to ask.

I had a Spohn chassis mount TA and I did not like the vibration and clunking. I couldn't use it with my true duals, so I got a UMI tranny mount TA but also got their front torque arm relocation crossmember. It moves the front mount from the tailshaft to the transmission crossmember. It's good and solid, bites hard, and doesn't transmit nearly the noise and vibration that the Spohn did.

I have UMI tunnel mounted and I did notice a tad big louder whine from my rear but noticed no extra vibration or clunking probably because my exhaust is so loud but I haven't noticed much of a difference
