I started thinking about this after watching the Rally NZ last night.
They had this cool animation showing how a production car and a rally car would take turns differently at speed. It showed the production car pushing to the outside and the rally car hugging the turn perfectly. They said that is mainly due to the rally car's 50/50 weight distribution.
They said that they actually add ballast to the rear of the car to achieve this. My question is - would anyone go that far in their production car? This, coupled with a very nice suspension setup would create a canyon carving dream.
