personally if i was sure i was selling my lude next year, i'm not sure if i'd want to install a $400 - $500 suspension set up and worry about part-out the following summer or so.
if you are sticking with the car, i would say save your money for Teins or some other full coilover system. i've had Tein SS on my car for a few weeks now and i can't say enough about how well my car handles than before. it is my first and last suspension setup for this car

.
all my friends with seperate spring/shock combos love Koni Yellows.
