Rear only on mine. Levels nice and I didn't even need to install the adjustable panhard I bought.

I had the Roush rear springs on my car.

This is the stock stance (sorry, can't seem to find a bigger picture)


Then with the Roush rear springs, stock front springs


I have since changed to the FRPP springs in the rear, but still stock front springs:


The stance is about the same for the Roush and the FRPP - but the FRPP don't feel as low when I get in and out of the car, and the ride is a little easier.

I compared the springs when I did the last swap - of course these are uninstalled so you don't have the weight of the car and the effect on the spring rates (stock - FRPP - Roush):

I did roush rear springs only, leveled it out and the **** didnt sag when I punched it like stock.

DITTO...roush rears only on mine too!

I did the rears also but finally put on the roush front spring with my stock struts and shocks lowered the front just right with the 17 inch bullits and the ride is really good for everyday and in hard corning.

So which FRPP springs are those?? P or K? Either way, can post up the height of your rear fender?

Thanks!

My dad went with the Roush rear springs and stock front springs on his 08' GT. He actually went with D-Specs and the car looks great and rides great too! No pics unfortunately..

I don't have pics right now but I had the rears only on my 07 and it looked perfect. I'm considering doing something similar with my 2011 now.

Sorry, I didn't see this until today. And then I realized that I'm not sure if these are the P or K!

Here is a close up showing the part number:


It measures 28.5" +/- (passenger side is just a hair lower) through the center of the wheel to the top of the wheel arch

They must be the the "P's" as the Ks have a 1.5 inch drop and yours sits at almost the same rear height as mine with Bullitt springs installed.
