Even with shipping(30 per pair) it was worth getting them sent down... DO NOT SKIMP ON TYRES. I have ~180rwkw, I had advan neovas, i was having serious traction issues, KU36 and a good alignment has helped this. An RB25 has more torque than my 20, so you will get out of shape more easily, so please please please get all new tyres. If i could of afforded it at the time, I would of gotten better rubber, but I am happy with the KU36.
