Hey guys! Would anyone happen to have the install instructions (or a quick how-to) for this unit?

Searched, but a lot of the discussions have been archived by now.
It's probably damn close to self-explanatory, but I hate to get the car on the lift and not be certain.
Thanks in advance - much appreciated!

I'll buy it if you're selling. I forgot all about this brace form 10 years ago, I figured they stopped selling them. I've been tinkering with a way to change the natural frequency of the PPF and well duh this will do that.

Apples/oranges but my PPF is a source of significant NVH, well VH anyway. I'm not sure of any performance value, but may be worth a try to enjoy the car more. Just like power steering damnit. Still working on that one.

Resonating frequency. You know when you have a PPF out of alignment spec it makes some pretty awful vibrations? Adding more mass can reduce the resonance/vibrations as well.
That said... i've never really found the PPF to be an issue when it comes to NVH, but who knows what's going on with what Tim's done.

If you were to do something to the PPF, I'd weld in a C channel on the PPF near the trans. One it would box the open side of the C which is what you need to do to really add any strength. Second it would act as a safety hoop if the front joint goes.
Then I'd do similar but bolt-in on the rear section. That way it would still be easy to remove the driveshaft.
