Just curious, but has anybody gotten the extra body stiffness upgrade for an LM car yet. I did La Sarth 24 II (w/ out chicanes) with my Black 787B, and of course the thing needed a refreshement. Would the body stiffness increase the longevity of the frames stiffness? Does the added stiffness cause more understeer, like in the BMW for example? I getting ready to complete La Sarthe I with the BMW, and would like to know before I potentially mess up the handling perminently. Well I guess I could always save up another 4.5 mil to buy another one, but I sure as hell don't want to.
