The Kumho V700 are less grippy give you a bit more slip and last a bit more. And did I mention they cost about 1/2 as much? Really all Type R compounds will only last about 5-10K at most and considering you are going to be pounding on them even less :-) So expect to replace your rear tires every 6-12 months depending on how you drive and how hard you drive it.
So I guess you decide.. And I am running out of money let have some of yours :-) Things add up very quickly.
