Most people do the 5-lug swap to have a wider variety of rim choices. If you're not going to be swapping different styles of rims every five minutes there is no benefit for swapping to a five lug set-up. There will be those who will say "five lugs are strong than 4" which is wrong. Regardless of lug pattern the stock wheel studs break easily and unexpectedly if you use slicks. Stock axles are fragile, too. Some will handle high HP some won't. 28-spline axles are like butter and strip/break if launched hard enough. On the street only they CAN break, but it's unlikely. If your intention is just to get better wheels for the car then you're good to go. Other than that if you're not planning on a different style rim or upgrading anything else then it's a pointless swap.
