You can only get so much handeling from f/g/f cars because they were emergency design cars so that GM could keep up with the mustank. Year One has that trick suspension set-up but it's a boat load of money.
Through the years, I have always respected the car for what it is. I've asked it for much as far as cornering goes, and the only demand I have ever placed on the cars is that when I crack the whip, they take off in a straight line. Just my $00.02.
