I think you need to re-visit your wheel and tire choices. The front wheel you're looking at will work fine but a little bit more offset would be better (22mm is perfect). On the rear, 20mm is too much offset. For a 9.5" wheel, I think you need about zero offset, for it to look right. It's very important that the wheels are hub-centric too. They need to have a 62mm center bore. As far as your tire choice is concerned, a 245/45-17 is too tall up front. Consider a 235/40-17 or 245/40-17. At the rear, a 285/35-18 or a 285/40-18 will work. Keep in mind, there's enough room for a 335 width tire at the rear on a stock bodied Pantera.
