    Hi all!
    I have a set of Porsche Boxster S 986 Brembo brakes lying around and would like to fit them to my Silvia S15.
    Has anybody done this brake conversion before? If so any tips/parts you used?
    Any advice would be much appreciated!
    Cheers

    I don't know the answer to your question unfortunately but if you can get them sold, there are plenty of 350Z front brembos are available from breakers for around £350-400 which are bolt on to the S15(except expanding the caliper mounting holes on the knuckle)

    Yeah that sounds like a plan cheers!
    Do you have to drill and retap the hub on the s15 for the 350z brakes to mount correctly?

    threads are on the caliper, knuckles holes gets sandwiched between caliper and bolt head so no thread. Stock bolts are M12, 350Z caliper bolts are M14 hence the hole on the knuckle is a tad too small.
