Where the lateral link rods meet (along the center line of the car between the rear wheels) is a good place. I don't know how accessible it is with your dual exhaust. My exhaust blocks it so I can't use it anymore.

Otherwise I use the piece of metal just forward of the rear wheels just before it curves "upward". The car has no true frame (unibody design), but those are as close as you'll find to a frame rail as there is on the car.
