I have this on my supra right now because the rears wore out faster. I do not recommend do this if you can avoid it. As Andi says, if you set it up wrong you get some unpredictable handling. Take for example my daily driver/autoxer, snap oversteer on a fwd car is very bad and could result in an unfortunate close encounter with a guard rail at 40mph.
Someone correct me if I'm wrong, if you have to run different tires front/rear I would run a high traction tire in the rear and lower traction in the front so that you would always push.
It's not about setting it up right or wrong, having different tires front to back is just plain bad because.... remember, a tire isn't simply a "high grip" tire or a "low grip" tire. Tires have complex multi-dimensional grip curves depending on a lot of factors including temperature, moisture, amount of standing water if any, etc.. Tire A may have more grip than Tire B in the dry at 70 degrees, but Tire B may have more grip than Tire A at 150 degrees.
What does this mean? It means as you're driving the car, the handling of the car will change, i.e. the handling is not predictable. Anybody who was at the Tx2k1 blimp base remembers how sideways I was at every single corner. Why was this? I had S-02PPs up front and Pilot Sports in back. At normal temperatures the car was pretty neutral and predictable. But the Pilot Sports get greasier / lose grip with temperature more drastically than the S-02PP's.... which meant that as I raced on the road course, each lap would cause the rear end to become more and more slippery. It made for quite a show but like I said....... don't do it.
Get the same tire all around.
