I'm taking my 308 to a track day next month. She had a major service about a year ago, so theoretically all squared away... Any of you who track your 308 or similar car have any "must" modifications to suggest? I have heard horror stories about brake lines breaking in other marques, etc. Obviously, good rubber, seat belt and helmet.... I am talking about the car. thanks... by the way.... this is purely for fun, and I plan on doing it a couple of times a year. The car is primarily for pleasure, not racing.
