How many people push their Z that has T-Tops to the point that a slicktop's bracing would help? The Z comes with sway bars, if you put after market ones on, it don't weight no more. If you put strut tower bars on, that's like 10 lbs. How much more does an NA with T-tops weight over an NA slicktop? Some people actually so prefer the looks of a slicktop... that's fine. There's *MAYBE* a FEW out there that race so hard core that a slicktop would benefit them. Other than that, there's a reason not very many slicktops were importsed to the US.... because they wouldn't be in high demand by any means. I REALLY want to see what the curb weight difference of a NAZ with and without T-Tops is. I dont' see how it could be over 70 lbs though I guess I could be wrong. If the weight is that much of an issue, then I'd rather give up the weight of my power seats before my T-Tops.
