Well as I've well and truly "hijacked" Maddmike's thread, but with good intentions, I'll finish by adding that I have now completed the swap from KYB Gas-A-Just shocks to KYB Excel-G's. I'm very pleased with result for MY car. Shocks control the up and down rebound, not the handling. With Boss 153 lb spring rate rear leaf springs (Eaton's) and an Addco 7/8" rear sway bar, I can still slam it around corners, but without the thing hitting me up the a$$ over bumps. And to me, that's a win.
KYB's are a relatively inexpensive shock, but what people want to put on is their choice. These worked for my budget and requirements.
