Title: Options to support frame horns / shock towers without a roll cage.
Post by: BugBusBuggy on September 28, 2020, 14:57:38 pm
I have a full weight '68 beetle and I'd like to give my frame horns some extra help in dealing with my 2276 off the line, and possibly tie the shock towers too for good measure. For now, the car is mostly (but not completely) street driven so I'd like to look at options other than a roll cage if at all possible. It's not a daily driver, so I would put a cage in if it came down to it but I'm reasonably keen to retain the rear seat. To make things maybe a little more tricky, I have (and deffo want to keep) my big bore heat exchangers and CSP Python which rules out just about every alternative I've seen. 

Currently have a gearbox mid mount, decent shocks and that's it. Any thoughts / advice?

Cheers,
Dave.

I ran that set up on my oval pre full roll cage and it worked well. I ran it with rubber trans mounts, not solids

I ran a similar set up, but a bar instead of the angle iron and tied into the roll cage. Keeps the frame horns supported right at the end.

Thanks both, appreciate the replies. @Neil it's specifically options for without a cage that I'm looking for, although granted a cage is probably the simplest way, it's also possibly overkill on what is (at least for now) mostly a street car.

I did mean to add (but forgot! Bloody useless...) that on my car it transferred movement to the torsion housing. Had I kept it, I'd have braced from the ends of the torsion housing up to the main hoop, as the rear cross members had started to stress crack. It did have bars coming from that rear brace horizontally to the main hoop, which again, had I kept the car I'd have tied into the shock towers.

 Without a cage, you'd want to put a plate on each end of the bar across the back, and bolt it through the inner arch, with a spreader plate on the outside. If the plate is a decent size and thickness, you might be able to add tabs onto the spreader plate to link in the top of the shock towers.

Have you looked into a kafer bar?

Lots of companies off them, im running the Fast fab setup myself.  https://www.coolrydescustoms.com/the-stiffy---kafer-bar-system.html

In my 68 Beetle I run a Mohr Performance mid-mount, Gene Berg rear mount (traction bar), Koni dampers and 69 bus rubber snubbers.  Been racing for years with stock Swingaxle suspension and no issues. 2332 cc with 204 WHP .
