Is that part number for the 290x18mm(170) rotor? It wont work at subaruparts.com. Its a JDM part number?
My question is also if you look closely at the calipers you can see slight differences in them as well, not just different brackets. Do you know if the bolt pattern, caliper position, etc. is the same. Meaning do you know if the older style caliper will fit in the newer style caliper bracket?
I have only recently become aware that the rotor above was being used on the 2000+ B4s and GT-Bs. That is currently the focus of my search. Again a reason I was advising a few weeks wait for Ken, I may well have a better alternative. But, at this moment it is still speculative.
Cardin you seem to supply JDM parts, do you or can you buy parts from JDM Subaru dealers?
