Well i have loads of alignment posts on here and everyone said they were ok i think. Yes they've checked all the things you chaps have mentioned.
I think handling wise these cars are better off with the run-flats as the suspension is designed for them. I'm actually finding now since fitting the new pump the steering is returning a lot better. But car still pulls and wanders and you have to constantly keep it straight but maybe this is just tramlining. And if that's right then these cars are awful for it!
