Those camberboxes work wonders when installed in a Porsche. You can decrease camber after extensive lowering and it lessens diving under hard braking. Unfortunately there is not enough room in a bug unless you're handy with a large hammer
I haven't installed them in a bug, but I did on various track Porsches. I did however do a similar thing to a bug by elongating the holes, in which the M 14 bolthead fits, upwards and filling the bottom part with a crescent shaped piece of metal. This way I decreased the amount of camber. The reason for having too much camber was because the IRS-arm adaptors were welded in too low.
Keep us posted if you ever decide to fit camberboxes to your bug.
Cheers,
