Currently there are no plans to utilize the 360Hz option of iRacing because it doesn't add any actual value. It isn't a true 360Hz data stream. Instead it is a 60Hz stream and in each cycle it sends 6 samples. That's basically 1 current sample and 5 older ones per cycle. We only care about the current samples and that's exactly what we get with the normal 60Hz iRacing option. There is no point in sending 6x more data than is useful because that extra data represents what happened in the past, not at the moment.

If iRacing were to implement a true 360Hz output that aligned with true 360Hz physics such that each sample were meaningful, we would certainly give great consideration to supporting it.
