Help!!- I span my real car :(

[IceMike]

Just got home from a nites racing, and being tired i was drivin wot i would call like a granny and keeping the revs low. Got almost home and there is a small round about and as i went round it the back end of my focus let go and span 180 around into a kirb. There was a bang but im not sure if it was just from the tire hitting the kirb or wot, i cant tell cos its dark. the kirb was one of them angled ones, and i cant feel any dent marks on the alloy, but wot else should i look out for or try and listen for to see if ive done any damage. i know i should book it into a garage to get checked but i dont have any time this week.
