, i had a P3 service, supplied my own pads (ferrodo ds2500) had them fitted, skimmed the disks and also got a free m.o.t, from nissan slough, was something like £450 ish from what i can remember, give them a call. Ask to speak to a guy called mark, and mention my name, should be able to sort you out
And exhaust brackets, MJP do them around £15, but there the proper nissan ones, if not check out JDM on there web page
