I have been running these tyres non stop at the schumacher series and at club racing. I am astonished by these tyres! They've got to be the best tyres available for carpet at the moment.
1.They heat up very quick
2.They're instantly fast
3.There a very consistant tyre.
4. The gluing is of reallly good quality
5. The rim is virtually un-breakable
6. And last of all, They last a long long time with no difference in performance from the packet!! (Posted on 26/11/2009)

The sorex 28 jb's are a much more consistant tyre than the older version.
There is more grip from start to finish everytime (Posted on 26/11/2009)
