Best way I've done it, is to get a strap that can tie down the wheels like photo shown.

If not, get a shorts strap with two rings that can go thru one of the holes in the wheels. Put some rags around the straps and with the two rings together, attach you hook to it.

Failing that, there is always the front swaybar or the subframe. But wrap the strap around it - don't use the hook on it.

For the rear, use the big bar below the ZF that the rear sway bar brackets are bolted to.
