Hi There are a number of outfits selling cheap Kumho V70A trackday tyres presently - prices are around 60 a tyre when regular is 100-110 Beware. I am reliably told that all these tyres are hard compound only (not what you want unless on a big turbo motor) and have been sat in a warehouse for a few yrs - so very old stock and therefore getting less grippy anyhow CHeers Rob
