I've always liked the retro styled offset rollbars you sometimes see about, but really dislike the fact they are made from aluminium, and only rest on the upper parcel shelf, so don't offer any impact protection. After having this as an idea for about 18 months, I started to make one back in March, but properly out of steel and attached to something a bit more solid!
If you're a bit confused as to what I'm talking about, here's one I found earlier (hope whoever owns this car doesn't mind!!)...
I wanted the basic shape to be the same, but to go a bit higher to use the full height of the soft top. The rear brace would obviously go down to attach next to the suspension strut. The plan was to add a harness bar as well, partly to act as a cabin brace side to side. It was to be 2" od tubing (maybe 2.5?).... I also wanted to get the attachment points as strong as possible without compromising the seat belts, something that a lot of off the shelf bars completely fail at!
End of march and we had messed about enough, so we made a simple hoop to see if we'd got the seat belt fitment right...
Rear view, this is significantly higher than the ally ones, so is above the height of me wearing a helmet in a standard Mk2 seat.
Front view, plenty of space to the seat and the harness bar will be say far enough back to not get in the way of the seat even fully back. This also shows the bit of the shape I'm not 100% happy with, this one comes up from the bracket at about 80-85 degrees and then goes around in one bend. Ideally it would come up at 90 degrees for a few inches, then do a 15 degree turn and continue up, then do the rest of the turn closer in to the seat / headrest?
Better solution for the seat belt... on the ally one I had, the seat belt is pushed off to the side so does not retract as smoothly as it should. This one works perfectly!!
At this point, I decided to make this one to fit my Mk2 and we'd do a Mk1 version later
To be continued...
