hey bro...
on my previous s2k, i had put in a set of King springs , they felt pretty close to stock in terms on ride quality , however after 6-8months they started to sag quite abit my initial 1.5 inch became about 2 inches . Which made the car VERY low .

However, on my girlfriend's S2k , she had the OEM springs compressed 1.5 inches front and rear . So perhaps if you wanted to keep the same ride quality , this might be an option .
Also, the OEM springs are high quality so no worries about sagging .

It cost about $300 to compress and fit .
