What tyres/pressures were you running at Ford Fair and what steering mode have you got the car in?
Personally I run Paradas - 32psi (nitrogen inflation), sport steering mode - I had this on Eibachs and went around a track really well.
Car then went around with the RARB and coilovers and is now superb - dont be disheartened - try and pickup some second hand coilovers then you can get a bargain upgrade
