whats wrong with the stock sub frame? you think that one weights less??? have they decreased the scrub radius along with bump steer reduction design in the steering geometry? R&P setups typically dont last long on older cars due to the above reasons w/o redesign. Unless you want the 'bling' or 'wow' factor, I'd stick w/ improving your stock setup. there are easier and less costly ways to lower the stance on your car. If I were to replace my rear suspension, I'd go w/ Lateral Dynamics or an independent rear from a GTO or Viper w/ a 9" pumpkin. One of my future endeavors.
