I used to live in Little Stoke but same thing basically, but that was before I played iRacing (took me ages to bother to update the location),
Virgin were good though for the 3 years I lived there, pings in other games were decent, and a nice solid connection so i'd imagine it'd be fine for iRacing as well, only issue I had with them was the cap they put on you if you go over the download limit...
