I wonder if it is worth converting for 5 lug itr. I wonder if my 4 lugs will be strong enough to withstand 250-275 hp. I want to know whether to do the conversion before I buy the wheels. Thanks!

 

yeah you're fine with 4 lugs.
5 lugs allows the bigger brakes/calipers.. thats the best reason for the swap.

 

not really, the one extra lug bolt is usually there if an engine has lots of power, lets say over 300whp. even if you hvae 4 lug bolts i say it can handle up to 200-250 whp with no problem. i odnt no exactly how to say it but 5 lugs doesnt help anywhere, even braking. dont waste your money for one extra lug bolt that doesnt really do much other than make your car look a bit better than with 4 lugs.
