Is there a demand for 944 Harness/Roll Bar ?

[rothaus]

I like to check if there is interest for Harness/Roll bar for 944's. I'm thinking offer them, if there is enough interest.

The harness bar would be mounted at the rear seat belt mount and upper mount at the C-pillar. No mods needed in the car. Made from 1.5 and 1.75 DOM tubing, with 0.095" wall thickness.

Thanks

How does it mount to the pillar?

[tims944]

all depends on price engelbert !

Not going to buy one, but you'd make it even better by tying together in some combination:

1) the front seat upper seat belt bolt on the B pillar
2) the rear seat upper seat belt bolt on the C pillar and/or the rear seat back post mount (C pillar)
3) the rear seat lower set belt bolts (where the lap belt attaches to the body)

I'd like one. My car is getting a track interior as I don't daily it anymore.

I like the idea. The intent was to use the lower seat belt mount, and the c-pillar. The extended section to the B-pillar belt mount could be added. See below the blue, black and yellow lines.




It should be possible to install without removing the rear seats.

Maybe, but the rear seat will become useless and just extra weight.

I have a Redline rollbar in my garage, let me know if some pics and/or measurements could help.

Yeah, if you thought the rear seats were useless and just extra weight BEFORE, I can barely fit a sunshade behind my seats.

I'm interested. If you could make a quality one for under $200 they would sell easily.

I think they would, however, that's not realistic.

It would be in the 400 - 450 range.

I am interested, but would have to see design first.

[grendiers]

Mine is not connected to the 'B' pillar, don't see why it's needed.

Nice looing design... the side bowed out hoop is a good design.

Seriously... This "ROLL BAR" in the pic's would not sustain a roll over 75 - 85 MPH... in my humble opinion. (The Horizontal brace that attaches to the B-Pillar Seat Mount) would take about 1/2 of the blunt force of the impact in a high speed "Roll Over. Please find pic's of one I built in 1970 1/2 (Z-28) & another one I built in 2015 on a 86' (951)

1) You would need (2) (extra) (Solid Bars) (Not joined together with welds like in your last pic) in the center going from the top of the roll bar to the (Hoop) floor mount bar or going to the rear seat belt mounts.
2) (2) extra center braces going from the harness bar back to the seat belt mounts.
3) To be on the safest side of (NO) failure... I would install 3" (Tri-Gussets (3/16" thick) at each point in all the bar attachment points and very large 3/16" thick (2) (8"X 8") floor bolt in brace under the main floor.. (the main floor is the weakest place in the car to withstand a high speed roll over).
Just (MHO). I have raced in NASCAR, Trans Am, SCCA & IMSA GT and have built many a sway bar.
Ron... I wish u all the luck in the world in your design... "Looks Good"!

Thank you for the useful information.

This harness bar is intended to be used for DE, not for racing, where a full roll cage would be required. It is a harness bar with added safety.
