A low, conventional reach aluminum jack can be used under the chassis bulkhead (with appropriate rubber padding), directly below the door button, I think, to raise one side of the car. Then, you can use the two inboard GT jacking points on that side for jack stands. Repeat procedure on the other side. That is the "GT Guys" method for raising the GT on four jack stands. I use hockey pucks drilled and countersunk for a centering bolt/nut for each jack stand. If you use a special, expensive, long reach jack to reach the GT jacking points, where do you then place the jack stands?
