I'm experiencing wheel hop as well, but of a different sort. When accelerating, during shifts at high speeds, gears 3-4, there is a bit of vibration and slight wheel hop in the rear. I'm making 670whp, currently no DCT M3 is making that much power that I know of, so the rear suspension might need some upgrading at this power level. This does look like an interesting product and I sent them an email over a week ago but did not hear back, it might be in your spam folder, lol.
I'm not sure if this product would help over solid rear subframe, diff - bushings, and camber plates, but hopefully we can find out. There's been some great points made in this thread, let's see how all this pans out.
