I have a very nice aluminum racing floor jack that I'm not sure I can use on my Boss. My Porsche has 3 circular reinforced "cups" on each side that work nicely with the floor jack. I can use the center cup and jack up the whole side at once. On the the Boss all I find is pinch welds but no good place to use a floor jack. The jack is too high to reach the frame rails. I wound up borrowing the scissor jack from my WRX to jack up the car. I put the front jack stands under the main frame rails and the rear stands under the axles near the wheels. That worked fine. The manual says to NOT jack up the rear using the diff. Is there a safe/recommended way to use a floor jack? Thanks!
