Don't swap without removing from the rim, especially for the track. They're directional for a reason. Also, RA1's like a ton of camber (-2.5 to -5.0 degrees per Toyo) for the best wear. That's why most see outer edge wear first. It's very difficult to get enough camber on a street driven car.
edit: I stand corrected, it seems the directional tread is only a concern in wet conditions.

- The directional nature of the RA1 tread pattern is only applicable for wet conditions to optimize water drainage. If they are being used in dry conditions, the direction of rotation does not matter
