Has anyone replaced their OEM seat and 3 point retention system with a track seat &/or harness? I realize that it is not too difficult to pull out an replace the current seat, yet I am looking for a track seat with the ability to adjust its position. One alternative would be to just go to a 4 point harness with the current seat, yet I was unsure if there were good mounting points behind the seat for the shoulder straps, and if that would gain me enough body stability while driving hard on the track. Thanks.

 

Have you tried Brey-Krause ( I think I have the spelling correct). They make all kinds of seat and harness products for Porsche - maybe they want to enter the AM market?
