HR is quite a respectable company...

H&R supplied the springs from the (Bilstein) cup suspension used in the Porsche 944 cups, which is how they ended up creating a tüv-approved coil-over set for the rear. They do still offer a complete coil-over set for the 944 with a tüv certificate stating that it is to be used without the torsion-bars.

For the beetle however they only offer a coil-over for the front and non-coilover dampers for the rear, so they keep the torsion-bars in place, see:

This basically means
- removing the torsion bars and running coil-overs on the rear of a beetle officially isn't legal in Germany
- The 944 aluminium trailing arm and the 12(?)mm bolt for mounting the damper is strong enough to handle the loads it is subjected to
- The upper damper mount on the beetles chassis could be the weak point (at least it hasn't ever been tüv approved to handle the loads from a coil-over)
