edgeracing has the Rs2 and rt615 for 99.00 and 112.00
I have been tempted to try the Rs2 as I had good results with Hankook tires many years ago.
I love the Toyo RA1 but they aren't recommened for auto-x since they need some time to build up heat. At sebring, they stick. I had rt215's on the 240 and once I switched to the RA1, I was able to push the car much harder in the corners and brake zones.
