for the struts, if you are deciding between KONI yellows and KYB AGX's, its a world of difference. Ive been in cars with both GC's and Skunk2's. the skunks are definitely stiff and feel very strong in the turns, as well as the GC's. but the GC's didn't seem to be as bouncy. the GCs were with koni yellows. the cars with the skunk2s have either had koni reds or tokico blues. both are a pretty decent setup, but the skunk2s are going to give you a stiffer ride. my honest opinion would be to save up for true coilovers though. they are engineered together and you dont have to worry about finding a good strut to go along with the sleeves. and, they ride much better.
