Wat do u want in your rims?
If its just looks then replica rims are good enuf..
If u want more - maybe durability/weight advantages combined then maybe Replica rims are not good enuf..
Note tat original rims are expensive - l mean really expensive not like 30/40/50% more but 300% more..
So in the end.. its up to u..
BTW, weight is only one factor, durability is more than just weight, materials make a difference - meaning making a light n durable rim is not cheap.. making a heavy durable rim is easier..
