I have a set of legit mugen RNR's and they are "4lug universal" but it was for racing when the lug slots strip out you rotate the tire and you have a new set of lug slots rota knock offs only have one set of usable lug slots and I agree I'd drop the price down about 600 I got min for 750 with a rota knock off as a replace ment for the one cracked RNR that I still have otherwise they go for 1000-1100 wit slight damage
