For the moment, the GRP S4 is the tyre we'll be running wet or dry, same for all
I know there are wet tyres available from GRP, RC Octane has them in stock.
But we need to test them before we allow them to be used. What we don't want to get into, is tyres that wear out fast so that you need a new set every meeting, that would go against the principles of the class being cheap to run.
But we'll see, its all open for discussion
BTW .... first round of Rallycross is this weekend
