On mine I have AVO front shocks, brake steady bars, 4 pot calipers, new rear springs, uprated Armstrongs (variable damping) a Panhard Rod, wider wheels and fat tyres (22psi all round)
Handling has been transformed. No skitting, or skipping and can hit corners at far higher speed than before. She is very planted.
I'm not a racer, but try and keep to a consistent speed - 65mph on the straights, and the same round the corners. I find it very frustrating when you get people in the usual german PE sport saloons who boot it on the straights but seem unable to use the steering wheel when they get to a corner....
