Removing Upper PHB If you have an Adj. PHB is the Upper PHB still needed? Mine is really close to my exhaust.
Also, I've read that it isn't a good idea to run a PHB relocation on a lowered car.
Thanks for your answers and pardon my newb question
I tried searching but once again the new search feature has failed me

would like to know this also..
BTW I have found that if you search for just one keyword your results will be alot better, otherwise it seems to find all the words seperately and you get bad results.. just a FYI

Hello,
The panhard bar relocation kit will work on a lowered car but will sit closer to the PHB. You shouldn't have any issues. Here is a link to our set-up... if you have any additional questions please ask.

Thank you!

This just came up really recently in another thread, and many before but the search is basically non-existent at the moment or else I'd hook ya up with a few links. Anyway, the Upper panhard bar is there to take pressure off of the thin sheet metal bracket the panhard bar bolts to. Without it the bracket will bend and flex, causing the bracket to warp and possibly even get torn off in time. Think of it this way too. GM had to create tooling for that part and use up the materials to put one of those on every f-body made. If the car ddn't need it don't you think they would have left it off? I mean no offense to anybody because I love GM, but this IS GM we're talking about. They're famous for cutting costs where they can.

We always remove the upper PHB. never had any problems, granted 50% of the time we're mini-tubbing these cars and the PHB bracket gets cut and reinforced. The other 50% we just remove the upper PHB and keep up truckin.

Interesting views...I guess I will leave it on for the time being. I'll look more into UMI's relocation kit since I already have their Adj. LCAs and PHB and relocation brackets....
I too wish the search feature was up to par as I like researching issues such as this....

I know what your saying, but GM has proven to do things on these cars that is extremely unnecessary.. take the coolant line running through the TB for instance. They spent their time make and developing this, but everyone agrees its just plain unnecessary...TB bypass Free mod. This is the same thing, just because it is there, doesn't mean it needs to be. You should ask some of the hardcore weight reduction guys about this concept lol.
The PHB brace is necessary for strength. Do not take it off. I'm not a fan of the PHB relocation kits though I do sell UMI's for those that need it. And here's why I don't love those thing. Using them puts the PHB on an angle and PHB's work best level. The more away from level you go, the more jacking and arc effects you get. Yes, you gain room for exhaust, but frankly I think fitting duals is less important than having the suspension work right.
The UMI part is very nice quality, it's just geared toward a different crowd.

TB coolant "can" come in handy up north, not so much down here though. This is not one of the cases you are talking about though. That upper bar is absolutely needed for cars that do more than go in a straight line. The force being placed on that part is rather high. I'm sure you could come up with something else to brace it, but why would you bother? It would take some weight out, but how much by the time you finish reinforcing it? If you really want to get rid of it you could always put a watts linkage back there but that adds weight. So basically I'm saying leave it alone.
While GM isn't the smartest company with money, they aren't stupid and would not go through the trouble, time and cost of designing useless parts. Move over, the setup was designed around 1980 when tires were a whole lot less sticky than they are now, so I submit it's even more important than ever.
Further, don't you find it odd that while you want a stiffer PHB some think it's ok to take away a support that the PHB and the associated loads dump into?
I do.

I'm not saying it is or isn't needed, only that you can't say just because GM put it there that the car obviously needs it. I also was told that unless your car is in the arctic the TB would never reach a temperature cold enough to freeze shut needing the coolant to warm it up.. but again I don't know these things for certain only internet hearsay.. take the information and make a decision for yourself.
