"Jacking your 356 can cause damage. Our Jack Points transfer the jacking loads to the strongest parts of the chassis. Lifts can also use these locations with no damage to the bottom of your classic."
Allow me to humbly submit that anyone that can't jack their car up without damaging it has no business jacking it up in the first place. An AAA membership is much cheaper.
That said, it looks like an elegant solution for a spacer on the torsion tube/spring plate cover on a Spyder.
