I remember this was discussed not long ago. There was catastrophic transmission failure in a Z with ~500rwhp (if memory serves) using the hi-5. It's unsprung so I would think it's more harsh on the trans versus a sprung disc. That's what had me second-guessing the hi-5 and instead considering something like the Southbend TZR. I'm still undecided - lots of conflicting info.
