I am not surprised about the r34. They (nissan) went to a wider mount bracket for the brakes. I have come across that acouple of times here fitting r34 brakes to 180's. With r34 GT-r's you need the whole hub assy. 32 and 33s have no problems with part swapping. But the stagea looks smoking

with a r34 front end!!! Look to MASA for a kit(est.us$6000). What you looking for?
