Those Hankooks are a very tempting deal, but I just ordered a set of 245/40R17 Kumho V730s to try out next year while they're cheap at Discount Tire Direct. ($664 shipped thanks to my awesome wife's 5% military discount, otherwise it would be a bit under $700 shipped). Basically an extra $30 over the set of RS4s for me, and from all accounts the V730s are faster. I've been perfectly happy with RT660 wear on this car so hoping this will provide a similar value/overall speed with maybe a bit more life. Hoping to do a lot more events next year, also fun to try new stuff.
