To further update- my car now has a soft, comfortable rear suspension. I just picked up the car earlier this evening from the shop that replaced the struts. The factory OEM struts really made a difference. The car indeed had high performance KYB struts- totally different than the factory Toyota struts I just had installed. I guess I will place these "KYB" struts on E-Bay and see what I can sell them for. Thanks again for all of the information.
