with a cage yeah. there are arguments over yes or no without a cage (i vote no, but who cares for this thread?), but with a cage I dont think there are any arguments, a 4-point will be safer. Only thing with stock seats, which goes for oversized racing seats as well, is that if the shoulder belts arent close enough to your shoulders they may slide on the seat, but realistically even if they do slide they are still going to be at least as good as a stock belt since that can slide also.
