So I took a road trip and picked up some goodies yesterday. Here's a list of what I grabbed.

07 GT500 front struts with lower camber mounts
Boss 302 LS springs
Boss 302 LS rear sway bar w/links and bushings
19x9.5 chrome AMR wheels +48mm offset
Koni blue 1.5 drop springs (I believe they are koni's, but I have to check)

So now I'm looking on help with what springs to use and what tire size for said springs. Unfortunately I know the 1.5 drop springs will require some more mods to keep the front end in shape and the pinion angle out back in check. But will the 500 struts with boss springs all around help me over my base V6 equipment? Will the boss springs lower the car at all? Sounds like they may lift the rear a little even. Also believe Ill need new camber plates to run the 500 struts anyway, correct? I can get ahold of some Pirelli corsa's in a 285/35/19, two are used and two are new, and come with 3 stock Pirelli's from a track pack GT car which I believe are 255/xx/19.

What do I have here? A bunch of junk, or something to help me on the way to some better handling?

 

What do you plan to do with the car, that really determines what you need to do. The springs may raise the car all around since they are setup for a car that weighs more then your's.

 

Looking for less body roll and over all better handling over the stock. Its a daily driver, but I'm only about 3/4mi from my work place, so a firm ride is fine with me. I was curious if the boss springs might make the car a bit higher.

 

If you more or less want to keep a nice feeling ride get some sway bars. You will be happy. I am pretty sure you do not want gt500 springs. The front of your car.. I think will sit higher than the rear of the car

 

I have Boss 302 LS springs, the front struts are from a GT 500. And I have a complete Boss 302 LS rear swaybar setup I am installing. But I was wondering more about the struts being an upgrade or not, and If the Boss springs will lower the car also.

 

Struts probably aren't much if any of an upgrade since Mustang's didn't entirely handle well from the factory until recently, you will also be sorely disappointed with the Boss springs in terms of nose dive and body sway.

 

go Koni orange.

 

What are you really wanting out of your car? Boss LS springs are no different than Base Boss springs, the struts and shocks were different. The struts you have are simply an OEM GT strut that may support the extra weight of the GT500 iron block from 07 but other then that, they're not going to fully support stiffer springs.
The koni Orange is a good option, luckily we have them on sale.

Sorry to piggy back off this, but I want to add the boss 302 springs to my '11 GT. Why would this be a bad choice? I do not want to lower the car due to scraping on a very steep driveway but want better handling performance.

 

So these would work well with the standard boss 302 springs if I installed both of them to my '11 GT? It is a DD but I desire better overall handling performance.

 

They would work well, they're a bit stiffer than regular GT springs which is when I recommend Koni's. Wouldn't have any issue running the konis.
