Even in 97 it was still 5 lug in the US. We never got 4x114 ITRs here.How'd you find brake rotors from a JDM '96 Type R? You'll probably have to search on websites through Japan to find '96 rotors, the US didn't get the Type R until '97. I think the '96 R bolt pattern will be the same as the '97 R which is 4x114. The Type R got the 5-lug in '98. You should have better luck looking for '97 rotors.
I thought one model was sold in the US with the 4x114 pattern, not sure if it was an ITR, but I could be wrong.Even in 97 it was still 5 lug in the US. We never got 4x114 ITRs here.
