i remember reading a max poo magazine a few years ago and in it there was an inertia reel 3 point harness. It works on the same principle as an ordinary seatbelt but looks like the real thing. Was wondering if anybody knows the company that sells them and or of anybody who uses them and if they are any good cheers lads.

Demon theives do one, might be by sparco (memory isn't up to much at this time of night).

I don't know where you might get them, but the 4 point interia reel belts as fitted to the MG SV would be great.

Here's a link to the harnesses http://outmotoring.com/corbeau_3_point_harness.html
unfortunately it's a US site.
Corbeau seem to be sold as luke in the UK but it isn't on their site.
