Seb took over SZ from Greg and has grown the business considerably. Their SZ/RPS clutches are still available. Z-Speed is under new ownership but still lists the South Bend clutches they were known for. Don't know if they've changed at all.I had good luck with the JWT Hi-Perf and Greg told me once they're good to 600RWTQ when I was first considering E85. I recently bought a SZ High Five, mainly for the light shifting, but have not put miles on it yet. It's their go-to for high torque, but I'm not expecting great mileage. Some of the SZ clutches have been backordered, but Coz has stock. Coz also sells McLeod, which I have a lot of experience with on the SB Chevy, but none on a Z32. I heard they are going out of business, so I would be cautious. Some people swear by the RPS carbon, but I don't know if that's available anymore. I'm not a fan of multi-disks just because of the additional components and associated rattles and chatter. Good luck.
