I went with the bracket from Speedtactics for my 987 Cayman as it mounts to the rails just like the one from Mantis racing. It’s a much simpler installation than mounting it to the seats as you don’t need to remove the seats, disconnect sensor wires, etc. It can also be removed and reinstalled in under 10 minutes.
So I bought the Mantis Racing one — just installed yesterday. It is rather crudely manufactured but seems to do the job and was relatively easy to install (provided you have the odd ball socket that fits the seat bolts — Torx E12 btw)
Brian, with the Mantis Racing bracket did you have to remove the seats, or was it done with the seats in place. And does it work with the manual seats? Although I don’t think anyone has ever moved the seat in my Boxster.
You have to remove the front bolts on the seat rail to fit the bracket underneath (there are plastic covers that need to be removed to get at the bolts – they are replaced after – https://www.youtube.com/watch?v=YmGAspMqBRk should give an idea of how to remove the covers) — once the bracket is fitted the bolts (Torx e12) are put back in through the bracket and the rail and bolted down (36 ft/lbs is the torque requirement if I recall). The seat stays in place during the process.
Yes – the bracket works with manual seats (mine are manual) — the lever to unlock and slide the seat back and forth still works as designed.
If you need to be able to reach your extinguisher with your belts on how is this possible with a harness?
I can’t even reach my sunglasses when I forget them on the dash after buckling up. 🙂
