Im going to lower my 04 GT soon and want to know which springs to buy ? I want to lower it no more than 2".

Neither.. H&R is the only aftermarket brand Id roll on.

+1 on h&r supersports, they're the same price and I've heard great things. Eibach prokit isn't bad but people have said the sportlines are too drastic of a drop.

Both the Eibach PRO and Steeda SPORT are nice performance springs that don't sacrifice too much of your comfort on the street. The HR SS springs are little stiffer, but are a nice compromise between performance and comfort.

Between Eibach and Steeda- I say Steeda.

The Steeda springs will perform better than the Eibachs. Our spring rates are slightly higher and the springs lower the vehicle about 1.25 to 1.4 inches so we dont affect the front roll center as drastically.

The lower the roll center, the higher the spring rate you need to control roll induced by the roll center migration.

I cant comment on the H&R's as I dont know their spring rates, but their drop is more aggressive which means they cut both suspension travel and make the roll center even worse than the Eibachs. If they compensate for that through spring rate, this combined with the reduced suspension travel are likely why they would feel stiffer as Socalwrench commented.
