6 point harness

Following Baz's accident I am fitting harnesses. Right fella's I need a bit of advice regarding locating the the crutch strap mounts. This is a retro fit in an S3 with leather seats. Harnesses are caterham six point race units. The build manual say drill 10mm holes in the floor but rather unhelpfully does not say wear. I can see no reinforcing under the seat area. Any one got a phot of wear the mounts should be. I assume between the seat rails is obvious but how far back from the cross member that is the front seat rail mount? I also recon a bit of thick ally plate to reinforce the floor wouldn't go amiss.

On the metric S3 chassis there are steel brackets at the rear of the floor where it meets the bulkhead. They are on top of the floor so need to be drilled through. The straps pass under the seat and through a hole in the seat pan (not sure the leather seats are suitable). Again not sure about the imperial chassis is the same but maybe someone can confirm.

DCL Thanks
Hmm, I do have brackets at the rear but they are used to mount the seat runners. No other brackets visible. It is a 1993 chassis and I believe imperial, all standard with inertia belts and built by Caterham. I had wondered about 6 point compatibility with leather seats but I have seen others with a six point system fitted so figured it is possible. Certainly the straps seem long enough to reach around the front of the seat swab and the chap in Caterham parts also said they should fit.

Out of curiosity, why are you opting for a 6 point? Why not a 4 point system?

There is a good reason for my choice to go 6 point. My son is quite small and on a booster pad and tends to slide forward on the seat swab. With the crutch strap he is fully held in and the booster can not slide either.

I have resolved the fitting now. I have made use of the two rear seat rail mounts that pick up on the same points as the ones intended for harness mounting.

I have a 6 point, and use the 6th point when needed.
For basic road driving I tend to just use 4 points.
