Anyone fitted three point harnesses?

I'm thinking of fitting three point harnesses. I'm sure somebody must have already done it. How easy is it and where do you fix them?

Not sure what the benefit of three point harnesses would be - presumably you'd just use the three seat-belt mounting points, and hence just unbolt existing seatbelts and bolt in harnesses?

I would imagine you'd get a benefit in moving to four-point harnesses (i.e. fixed at both sides behind, as well as front 2 mounting points), but not sure how feasible that would be on a tuscan - on my old Elise, I bought a kit which just had a solid bar mounted on the two back mounting points (i.e. one from each side seatbelt) which ran across the width of the car, and that bar had four mounting points on it for the backs of the two harnesses - two for each side for four point harnesses - I'd imagine a decent engineer could fabricate one for you on the requisite strength, but I've never seen it done in a Tuscan...

(not the best description in the world, but hopefully you can see what I mean!)

Thanks Richard. I think the 3 poinbt harnesses provide better wirght distribution on impact compared with normal seat belts, which tend to load all the g-force on one shoulder - I think! My car's away at the mo at TVR Power having open heart surgery. Expect it back next week and will be able to investigate.

If you fit a 3-pointer make sure the rear strap is within say 30 degrees of the center line of the seat otherwise you risk being injured in a shunt, also (but less critical) within 30 degrees of horizontal.
