I found some last year for 270 shipped from a place called edgeracing online. I dont think they exist anymore...

Where else?

 

vulcan tire i think is where i got mine from. i forget if discount tire had falkens. there is better rubber out there now tho. if you didn't know the dunlops drizza z1 (i think) and kumo mx are a little better than the falkens now and the price is relitively the same. I'm the the rt-615 now and will probably move on to the kumos when they are done.
