Since you're autocrossing in SM, then you could go with the V710s. But, my guess is going to be that you're looking for a tire to serve as both a street tire and competition tire.

FWIW, one of our guys has a SM EF Civic, the Kumhos were a second faster than some Hankooks C30s.

IIRC, the RA-1 is a newer design than the V700. So, there may be some benefit from newer technology there, but that's purely speculation.
