I am used to brakes being fairly dismal, my other cars being a non-ABS MGF and a Triumph Toledo. So, I instinctively leave more room for braking than most drivers do. Also, as a magistrate, I have to behave myself so I'm not driving at the sort of speeds where brakes are likely to get hot enough to fade.
However, there can't be any harm in upgrading brakes, whatever the car.
Be interested to find out if your mods make a worthwhile difference.
