Best bang for the buck is H&R Sport spring and KYB AGX adjustable shocks.... about $150 for the springs and around $300 for the shocks.
Allot of people on this board have this setup.... I got those shocks on my car but have Skunk2 Coilovers and hate the coilovers.... my Girlfriends car has the H&R race.... and I love the ride but it is little to low for some people.
Cant go wrong with H&R... and KYB is the best bang for the buck.
Good Luck
