I always loved the way a rwd v8 look when fitted with larger tires in the back. I also thought about doing it on my Talon but mostly for looks.
In the March issue of SCC, there is an AWD 3000GT owned by GT Pro rolling on 245/35R-19 in the front and 275/30R-19 in the back.
Seeing that they would do that on their car, maybe I would do it also
