Well, I ran both configurations and can say that normal FWD logic applies to the FiST. While there are arguments for a front bar to keep the front planted and wheels level and in contact, that will help in long sweepers and literally hurt anywhere else. So for a track day or perhaps Nationals, with the right driving style, it might work.
For me however, the stiff front bar and stiff shocks allowed weight transfer under braking to happen too fast, locking up the front brakes easily. The car plowed like a Caterpillar DC6 and had zero traction coming out of the corners. The inside front wheel just spun and spun.
For small, tight autocross courses, OEM front and bigger rear is the way to go.
