[QUOTE="Norm Peterson, post: 16492356, member: 193960"] Can't tell for sure whether you're joking or if you know of a certain large thread elsewhere where the value of another kind of S197 chassis bracing was under discussion with the same 2 second lap time claim from having added it. (different vendor from either of the two so far in this thread, with his own thoughts on how to work with PHBs). The Cliff's Notes version is that the S197 chassis is stiff enough to where added stiffening can't improve the [b]car's[/b] performance by that much. But it is possible for additional bracing to improve driver confidence by making the car feel "more solid" without making it much stiffer. It's a perception thing that can make it easier to drive the car harder than you might in its absence. I even made a few chassis twist measurements of my own, and saw for myself that there just isn't that much chassis torsional 'flex' for added stiffeners to take out, no matter how much stiffness they might add. FWIW, even the early S197 Mustangs are about 50% stiffer in torsion than the C7 Corvette, and well over twice as stiff as the C5 Corvette . . . Norm [/QUOTE]
