This is it. The new thing that glues. It took me 2 years to have the courage to try something new. And after a lot of Internet research (some of which are very bias I have to add), I decided on the Yokohama Advan A048. They are in the size of 235/40 R18 91Y MH compound. MH compound is the hardest compound and the same compound used in the Lotus Exige models.
From comparing between the 2 tyres (the Bridgestone on the left; and the Yokohama on the right), the tyres look the same in width. Although the Yoko is 235 and the Bridgestone is 245, the square shape of the Yokohama means the contact part of the tyre of Yoko is the same size as (if not any more than) the Bridgestone. The tyre is smaller - as you can see on the bottom picture, and lighter - with even just my hand I can tell, and certainly the size wall is stronger (with a smaller profile).

I will track here of any track review, but these tyres are saved for the Nationals.
