Jake it's been some time, and the memories get a bit fuzzy now and then, but I seem to recall that we sold an aftermarket steel wave plate. I believe it had something to do with cushioning how the clutch pack applied. There's a couple of pro builders on this thread that can maybe clear this up for sure. I notice that there is only one steel plate that is waved out of the clutch pack you're showing. This makes me think that it is an aftermarket wave steel. However, you say steels and the clutches are warped, if so, then excessive heat would cause both types of plates to warp.
