yes, you can use it, but it's not really fun to drive in the lower series races since you can lap the field ussualy in 3 laps, but that's just my opinion.
Yes you can. I got tired of trying to win the All Stars event even after I got my Minolta. When I got the FGT, I used it for that event with no problem. Not as much fun as battling with the other cars, but it was finally over.
