"Is the 5 point necessary ?"

Are you going to track the car?  If not, then, no, you don't need a 5-point.  You probably don't need a 5-point even if you DO track it, if you get a barset with 3/4" tubes or larger.

Just remember, Kafer bars make the rear REALLY tight so expect some vibration transferred to the rest of the car.

I had a lengthy thread on here something like 2 years back when I installed mine and a lot of your questions were answered.  Here you go:

Since even a stock Beetle (with a stock engine) will bend the frame horns when driven "spiritedly" unless there's an engine support bar mounted, any time you triangulate the shock towers/frame horns  to stiffen up the rear of the car it's a good thing. Whether the 3 point is enough or the 5 point is necessary is going to be a great discussion, and the proof will be when someone with a 3 point truss bar runs it for a while (2 or 3 summers?) and the engine weatherstrip around the rear breastplate still lines up with the rest of the car. While I'm sure we have members that can vouch for the simpler bar now, I can see the extra 2 bars tying in to make a brace for rear roll bar supports.

I think a really healthy 2 liter+ could still benefit from an engine support bar, such as Stan and (I think) Bruce have designed and built. Al

Richard- A gearbox midmount like the pic below goes a long way to firming things up as well. Even with the truss bar it's possible to tear up the front trans mount without the extra support.

Did anyone who installed either the bugpak/empi 3/4" bars or the  kustom1 1" in- house truss bar have interference issues with heater boxes? Or the starter?

my car is 2013 VS, 1915mild engine, swing Axel with a IMI101 high torque starter and stock heater boxes?

i had read some old samba post that referenced potential interference issues.

Figured I would ask before I crawl under the car and start the install process ;-)

many thanks!

Thanks guys.   I guess this is why the kustom1 guys along with the truss bar kit sent me two extra attach tabs---  Just in case I needed to cut the existing ones and re- weld the horizontal bar tabs in a different location ( closer to the bars end) to clear any interference with heater boxes.

will save playing with this for a long weekend...

thanks again
