I just got off the phone with the owner of IRP (Great guy :thumbup. I guess they are waiting on a new machine, and their delrin supplier just sold the last of it's stock to a competitor. ETA on the kits is 3 weeks for the Race kit, and 6 weeks for the Street kit. Race should run between $55-$60, Street kit should be about $110. I asked about the integrity of the Street kit brackets, and he said he unfortunately doesn't get a whole lot of feedback on them. He has seen them bend up (So have I), but it was a pretty bad crash. He does recommend cutting the plastic and using the Race kit if you are doing any track time. Just thought I pass this along.
