I have them as well, and they are pretty good, so I'd recommend them. I cut my front springs one coil and they are pretty stiff; the ride up front is pretty harsh. I also have polyurethane bushings all around - great in the back, rough up front. I'm used to it now. If I was to do it again (and it looks like I will be on another Fiero) I'd go with the ST springs in back and Rodney's lowering ball joints up front on stock springs. I also recommend the big n' little rim combination: I'm currently running 16 inch rims in the back and 15's up front. My next set of tires will be 50 series all around, not the 55's out back and the 60's up front. the rear is actually a quarter or half inched lowered more than the front, but the rim/tire combo has me pretty level. You can't tell at a glance that the rear rims are larger in diameter, but it does a nice job of visually filling the rear wheel gap.
