I was wondering about the 07 Pony Package sway bars? I crawled under my car and found my rear bar, but could not find the front...does that make any sense?
Does anybody know what is supposed to come with the package and is it worth it to upgrade to the GT (rear) and/or GTfront. I tried searching past threads and had trouble finding a straight answer. Thanks.

If you have pony package you have both front and back. Some will say they are not the same as the GT but IMO they are. Someone said in a earlier post there was like a 2mm difference in the sways on a PP and a GT. Even if they are different part numbers and there is just a couple mm difference I wouldnt worry about GT take-off's. There is no way you could feel the difference in 2 or 3mm and there could even be that much difference in manufacturing.

31.5MM V6/pony package front sway bar.
34mm GT front sway bar - 2.5mm thicker than V6/pony package.

no swayrear V6 [:@][:'(][][:-]
18mm rear sway on V6/pony package
20mm rear sway on GT - 2mm bigger than pony package - 20mm bigger than a V6 (none).[:@]

It pays to swap 31.5mm and 18mm pony package sway barsto
34mm and 20mm GT take-offs and replace the bushings with
polyurathane bushingsat the same time. What an improvement.
I did it and its like night and day with the predictability of the handling.
Worth every penny I spent ($75 or so total including the poly bushings).
I have an extra 34mm GT front sway if anyone is interested. Its a new
takeoff with the rubber bushings and brackets just waiting to be installed
on the front of a V6 or a Pony Package V6. You just pay UPS freight
to you from 72703.PM me if interested.

Im telling you 2.5mm front and 2mm back will make absolutely NO diefference. The average pinky nail is 10mm across! It has to be all in your head. I agree totally that replacing the bushings will help but it is total waste of money to replace pony package sways with the ones off a GT. Manufacturing process can vary that much, 2mm is nothing.

Its not the size but the compliance of the different sizesway bars.
The size is referenced to because a force meter is not available
to everyone. I have tested the afore mentioned bars and there
is a BIG difference. But to each his own. Do what YOU want,
not what other Forum members think is right.[:@]

Oh yeah completely, it's what you like. And im not bashing you 157db, dont get the wrong idea, its just hard for ME to upgrade the sways from my PP to GT's when there is that little difference. And I dont know maybe they are even made from a different material, is there a weight difference?

No weight difference. If you swap the rubber bushings (100% improvement)
for Prothanes Polyurathane, (everywhere you can )(Moss Mustang),
you have to remove the sways anyhow and the one time non-reusable fasteners
as Ford like to call them. I would go the extra mile and swap the sways at
that time also. I didnt replace my fasteners as I had to buy them for the rear
($40) and just retorqued them properly and used some blue loctite on the fronts.
My front sway only V6 all over the road uncontrollable went to a very predictable
little hot rod. I did rear Roush springs and shocks and poly panhard bushings
but just because I had to remove the panhard when the rear springs went in.
Its a whole new ride suspension wise now than when I pulled it off the lot some
10 months ago and nearly swapped ends gettin on it. It bites hard and consistent
around corners now and very predictable.
The 34mm front GT sway weighs more than the 31.5mm V6 front sway.
They arehollow and the wall thickness is also different. Thicker for the GT.
They are hollow for more surface area to weight. More surface area equals
more tensional load per pound of material. Try and bend a straw holding
by the ends only.
So you can’t go by the O.D.as acomparison to performance.
Did I forget to take my happy pills today?

Wickerbill

yeah but what did you do about your wiggle pin falling out of the wobble shaft?

Interesting discussion,
It's hard to argue with someone who has actually changed the parts and has noticed an improvement, but at the same time it does seem silly that it would make such a difference. Just for the record though, Circumfernce = Pi x Diameter, or also C =Pi x 2 x radius, so it is not exponential. I may just start with a new strut bar and work up from there.

Thanks

Sorry, it's late and I mistook compliance for circumference in the last post...my bad. But on that topic if you are talking about area of the circular bar on a plane then it would be Area=Pi x Radius squared. Anyway, now I am just rambling.
