I think the advantage is they do seem to stiffen the cars a little.. And if you add proper pads under the rear deck welded to the sides for the bar to bolt or weld into they will ne more effective.. But most are "show bars" and wouldnt be a big help in a roll.. Especially without a diagonal front bar to brace at the firewall.you're better off w/o one... These just provide the illusion of safety. All of the roll bars available for the Alpine/Tiger just bolt to the rear deck sheet metal and will collapse (or tear out) if you really have need for a roll bar... as will the w/s frame which will just sheer off the front of the car.
I can't begin to tell you how many cars I've had to repair due to being drilled for useless roll bars.... and they generally look like CRAP.
Besides, you'd really have to expend a huge amount of effort to roll a Tiger![]()
I have to agree with you about being an illusion. We have a Harrington that spent most of it's life until the wife bought it in the 80's as a race car on the east coast. The bar set behind the seats where most of todays bars set but it was bolted thru the X Frame and had a brace that went to the center of the right front floor and bolted thru the X frame. I'm not sure how good that would be but that would make for a very difficult road car for someone on the passenger side. Probably something you wouldn't want in a Tiger.you're better off w/o one...

We have a Harrington that was raced here in the eastern part of the country back in the 60's and 70's. The roll bar was secured to the X frame behind the seats and it had a brace that ran to the right front floor and it was also secured thru the X frame.I think the advantage is they do seem to stiffen the cars a little..

I suspect the usual bars are a bigger hazard to street drivers in most situations.. As your head can contact them and it would be like being smacked with a metal bat in a rear ender.... Can pad them.. But.. Still not fun... Could add a head rest to it...
But again.. Agree with Shaun... They tend to ruin the lines of the car..
