Race seat options?

Hey folks- I’ve had several track cars in the past all with rollbar/Seats/harness/fire and woulda like to do similar for the GT350R. Looks like Watson is a solid setup and need seats with mounting hardware (slider preferred) and connection points for the Schroth 6pt harnesses. Preference is a seat with HANS. I’m a medium/lean build 6ft for sizing. Thanks for any suggestions you have here.

Happy Thanksgiving all,
Mark
