I love my H&R Super Sports...they are a stiffer spring so the ride is rougher than stock but the handling and looks are well worth it imo.
H&R, Eibach, BBK, Ford Racing, and SVE Economy Springs are a few popular brands. Most offer different rates and drop heights so do your homework before buying springs.
