i am going to change mine out as well and i have already bought the adapter fittings. i like the idea of not having to use stud extensions on the booster, but would rather buy the cheaper and more easily attained 370 master cylinder. i will use a new bmc, as the used ones on ebay have probably sat and seals have probably dried out. so if the r35 booster is compatible with a 370z bmc, that will be perfect more me.
