I drive pretty hard with stock suspension and tires. lots of roll. fairly predictable handling, pretty hard to generate oversteer, car tends to go into a 4 wheel drift (not understeer) and it's easy to manage. Used to have a 71 Peugot that did the same, fun (better brakes). I prefer the cornering when I have a passenger, loaded.... well you have to follow your feelings. One of the advantages of the skinny tires is that they break loose pretty early so the change is not as violent as in more modern cars. My biggest concern would be brakes, I've never smoked them, but on mountain decents I use my gears and I let the engine rev pretty high to keep things cool. Have fun, Patrick.
