The panhard bar is needed when u go aftermarket wheels with more offset. U can really see how the rear is not cenetered between the quarters. I'm running a 20x12 rear rim with 315s and without this bar the one side would be hanging past the body which would look like shit..
lowering springs w/o other upgrades?

eeekkkk i guess i wont be going this route!
This! My car is under the knife as we speak. I should be getting her back in a few hours. Went with the Roush DUB/Eibach kit with STR.T shocks/struts and BMR Panhard. I did everything since I didn't want premature wear of my shocks. I figured that'd be more labor down the road. Also got the BMR because even from the factory, my wheels line up to the left a bit. It's pretty even with the wheel well on the driver side and inset about an inch on the passenger side.
Do you need new upper strut mounts when just changing springs?
You dont, but some report their stock strut mounts falling apart and others dont. Some have popping occuring after install and some dont. Its worth it to get the GT500 strut mounts weather your doing springs or a complete strut and springs setup.
Whats weird is when i had K springs installed with STR's i didnt need much of an alignment change or camber adjustments. After a few months the ride bugged me so i went with the P springs which are only about 1 inch drop front and rear and had to order camber bolts.
To sum this up. if your gonna lower the car, buy springs and depending on your level of drop apply camber bolts and panhard bar accordingly.

I added the Steeda "Boss" springs because I did not want that much of a drop but wanted a higher spring rate than the FRPP "P" springs. When I talked to Sam Strano about a suspension set up I asked about a panhard bar. He made a comment that I had not really thought of. He said the Boss302 is lower than a stock GT. But the panhard bar is the same. He recommended installing the springs and then see if I needed a panhard bar. He said if the rear end in still centered well not to bother spending money on a new panhard bar or support brace. With the 1"(ish) drop up front 1.25" of the Steeda "Boss" springs my rear end shifted less than a 1/16" to the one side. Using a plumb bob to measure this. Saved me money which was nice.
The 1.5" drop springs like the Steeda "Sports" or FRPP "K" springs you will most likely need the adjustable panhard bar to center the rear.
I ended up installing MM C/C plates on my car. So I have a brand new set of Eibach camber bolts. If you want to meet up for them you can have them for $15. Part number 5.81260K.
I have GT500 mounts, Koni STR.T, and the Eibach/Roush springs installed and the ride is outstanding. My Eibach camber bolts just came in yesterday so I plan to get an alignment done this Saturday. My only complaint with my setup is that I hear a low, faint noise when the springs compress. It's not quite a squeak. It's more like "Ricket" sound. I'm not sure if its the springs, struts, tires, or mounts. I can't figure out what this sound is for shit.
Kinda of a mix. I used metric on almost everything except the the strut nut that bolts the top hat on. I was able to use one of my angled SAE box ends on it.
Here is a good write up on the lowering spring install.
I take no credit for this other than copy and pasting the link. haha

When you installed your springs did they have a coil cushion on them? like seem in this picture?

Yep we double checked.. and the GT500 mounts arrows
are pointed outward
none that I can tell but will triple check the wheel wells and tires. I'm still riding on stock 18s so it shouldn't be an issue with this mild drop.

I just noticed my car doing this today. It's been fine (or I just now noticed it), but at very low speeds (<5mph) I get a creaking kind of pop that I can feel through the brake pedal and hear on the driver's side. You can feel it if you put your hand on the sidewall of the tire when someone rocks the steering wheel back and forth slightly. I only feel it on the driver's side, which also happened to be the side that the mount came apart on me when I did the springs.
