You could do something along the lines of Ground Control coilover sleeves with a nice shock setup. I prefer the Koni Yellow shocks.
When i had my GSR I went through 3 suspension setups before i actually found one that i liked/rode smooth/drivable!
The first setup, because i was young stupid and just learning was a set of H+R sport spring on stock shocks...biggest mistake of my life, way too low for my taste and stock shocks on those springs rode like crap. eventually upgraded to the tokico illumina shocks with the H+R springs and still wasnt what i really wanted my car to handle like...still way too low for me.
Last suspension setup i did was the Koni yellow shocks with Eibach Pro kit...perfect for daily driving and ride height, and dandled awesome through the corners. If i was to do it all over again and i didnt already have a nice set of coiovers on my new car i would definately get the same setup again!
