Well... the springs have had some time to bed themselves in now, and she seems to handle corners VERY nicely now!! I can throw her into a bend, and she'll hold in there for longer, and at a higher speed too.
I think the Falken 452's definitely have a part in this as well. They stick very very well, sometimes TOO well. I threw the car into a right right hand turn the other day, and was preparing for the car to drift left slightly, but it didn't, I almost over steered into a car park!
