i have eibachs and AGXs, but i want something stiffer. seeing as how you already have the shocks i wouldnt suggest going for some koni yellows, but i think youre right on in going for the RSR springs. good, stiff stuff.

eibachs and Agxs are good for streetability and infrequent track use, but more often than not i just keep wishing i had some stiffer springs.

and you dont need coilovers, not until you make that car a bonafide track slut. its just not necessary... sure, its uber-bling, but you can save that money for the things you will very likely break if you start drifting.
