Think you are better to make some wooden blocks with a shallow angle ramp up to the top, drive the car up onto two of them then use a larger high-lift (quick lift if you can afford) as Marpar mentions above, get a jack with a wider track and good stability.
I have one of the aluminium 1.25t racing jacks from Machine Mart, it is OK but easy to damage the ram housing as there is no over pressure relief valve
If I were buying again I would go for one of these, but whatever you do get some good axle stands and stay safe.
