Had installed for 3 weeks. Still looks new, comes with BRIDE Type-FO Seat Rail - Toyota Supra (A90) / BMW Z4 09+, F36, F82 (US Driver) https://www.evasivemotorsports.com/store/product/bride-zeta-iv-gradation-silver-frp-shell/...
So I've put a couple of hours in the seat so far, its fairly comfortable and VERY snug. I am 6' appx 190# and barely fit, height/visibility is not an issue. Attached are some images that might help your decision.
