what the guy said before about corolla being more responsive could be correct in this way - take autoX, touge and circuits - in these situations, going from turning hard left to hard right (like slalom) is often required.... considering that the 2 cars (ae86 & 240sx) have the same basic layout (FR), and the only difference is about 500lb, the lighter car will be more responsive, relative to inertia, momentum, impulse and such.
