I've got a 1990 2+2 with its original 63,000 suspension minus Z1 street FUCA's and tension rods. The spring sag is different for both the front and the rear and side to side so when I get around to replacing the struts, I would like to address the springs as well. Since OEM springs are no longer available, would you say the H-tech springs are the most "stock-like" in ride quality? I drive on some very crappy roads, so I value comfort over anything.
