The long awaited replacement for Michelin PS4S is finally coming. Lately as the tyre wars escalate with new UUHP tyres (Max performance) from most major brands, namely Michelin PS5, Goodyear Asy 6, Continental CSC7...
I was told recently that there are some problems with the td05 20g highbrid, so now only available td05 18g, any comments/using. Looking at doing this upgrade.
BTW what should my min size injector be for this upgarde?
