When are these out? local tyre monkey reckons they are going to be fitted as standard on new TVR's. Should be a true replacement to the excellent SO2's

 

There is already an S-07 on the RX-7 Bathurst...

Look at the 2nd of the lines in the table - the tyre is mentioned in English. Oh, and they are pretty good too

Bridgestone does one offs for some special versions (a la the RE-070 on the STI RA spec C )- so anything is possible. Still think the s-03 is under rated...IMHO natch
