I have a 2011 GT with the Brembo package. After some further research I've decided on this suspension setup:

Koni STR.T struts and shocks $370
GT500 strut mounts $110
J&M Adj PHB $120
Steeda PHB brace $100
Steeda FCA brace $70

This setup will run me $770 + springs.

I'm trying to pick between Eibach Pro-kit springs or Ford Racing K-springs. I want a nice ride and I want the car to look level, no front rake.

Are they both fine or is one better than the other?

 

How much of a drop are you looking for? I would go with BMR.

http://www.brenspeed.com/sp009.html If I could lower mine these are the ones I would purchase. I have yet to read a bad review of these.

 

I'm looking for 1.5" of drop. I've never heard of these springs and they say 05-10. I know the suspensions are the same but I have a hard time buying something that doesn't specifically say it works for my car.

 

05-13 all use the same springs with some minor differences between suspension modifications. I ordered the BMR springs to go along with the Koni STR.Ts during their sale, just waiting for them to arrive. Never heard a bad review about them if you're looking for a balance between comfort/performance.
