With the OEM tires they use to skip, with the GS-D3's it grips but then you get the sensation of the tail coming loose if you push any further, which it should not happened with the tests I am making, the OLD NA stayed more planted and so does other cars. SM, I can understand about the springs length and load but the GM engineers should have adjusted them to behave on the GXP like it's counter part, but something is off, at least to me. Thanks for the info, maybe if an engineer from GM is reading this and some of the comments made on the link I posted could shed so light on this issue. I want the overall performance of this car to equal its handling, and that is not happening.

Looks like you've got something here, LV. As was stated by a previous poster, could the handling problem you describe be caused by the difference in weight distribution of the GXP vs. the NA Sol? And might it be improved by putting the lowering springs on? Different sway bars? Larger footprint rear tires? It will be very interesting to see how the GXP is set up for racing by GM. I know most of us wouldn't want the rock-hard suspensions that racers use, but certainly ratios of front/back sway bar diameters, spring rates, and tire footprints may be useful information. Sure is interesting that it appears that GM released the GXP with lower handling thresholds than the NA Sol
