Quick update for reference: due to the size of tyre and limited budget, I didn\'t go for a semi-slick this time. I did veer back to just ruining the tyres that were on the car, but after finding a number of reviews of the front tyres, where delamination of the rubber was reported several times, I decided that a new set was called for. After all, it is the only contact point to the track/road, and I wanted to enjoy cornering, rather than slipping and sliding everywhere.
So after much reading around I opted for Yokohama Parada Spec 2. I have to say, I am pretty impressed with the dry grip these things have! I was pushing pretty hard into the corners round the track and they were certainly hanging on incredibly well. I\'m no expert, but for an almost budget tyre price, these may well be something others could consider. All 4 fitted etc, price was £360.
