so does the SC 300 comes with a amplifier?? because the sound is pretty impresive!!!!

My suspension has an issue. I just recently replaced almost all of my front suspension, except for the upper control arms and the springs. I recently drove my aunt's newer 2006 Camry and the ride quality is near perfect like it should be. I'm sure that when my car was new the suspension must have been better than what I am experiencing otherwise I doubt anyone would buy the car. My mother's 95 Camry is even smoother than my car. While going over bumps at a medium speed 30+ mph my suspension makes an awful thump noise. Its both the front and rear suspension that I get the "thump" from.

The newer 2006 Camry's suspension is quiet and very soft comfortable ride. There's no comparison between the two. In the front suspension I have replaced the lower control arms, upper strut mount, bump stops, end links, sway bar bushings, struts, and the spring insulators. The factory repair manual stated bottoming out can be associated with bad springs or just being overloaded. Granted, I know I am comparing a 13 year old car to a 2006 Toyota, but something isn't right. Currently I have KYB GR2 shocks and all the rest are new oem Lexus parts. What could I try to eliminate this uncomfortable thump I am getting when I drive over a bump. Nothing is loose, the suspension is all torqued to spec. Could it be the upper control arms or the springs? Its just very disappointing to spend all that money and still have a harsh ride while going over bumps. I'm just kind of lost with this. Maybe the springs just need to be replaced as well. Anyone else experienced anything like this. Or maybe I need to go back to the oem shocks/struts.

I got the same problem with my SC 300 94 but I haven't change anything from my suspension!!!I hate the noise but I just got my car 2 weeks ago so how much have you invest in changing all that stuff??

Well I just bought a SC300 1994 from my cousin for 500$ and I'm loving it.The car have 270,000 Miles (He went from NY to Miami so thats why!!) but it runs so smooth and everything seems to be wroking perfectly except for the control panel!!!! The air bag icon its On all the time same with other icon which i dont know the name of it. I think there might be a problem with the electricity. Well my question is How can I keep my Lexus SC 300 in good condition ? What kind of oil shoud I use ?? I just got my first car a few month ago (Toyota Camry 1991) so I'm a newbie with cars.

Edit: I just called him, and he told me he drived the car to Texas too so he made 2 trips NY to Miam, NY to Texas.
