Hi, Im Michael from Australia. I own a 71 240z which has over the last year been through a full resoration.
RB25det/FMIC/3" exh/AZC Coilovers/AZC 4 piston discs all round/new busings/r200 upgrade etc etc etc.
I am going through Engineering in Aus (inspections to ensure vehicle is safe after modifications).
Upon testing my rears always lock up first, which is a big NO NO. I installed the AZC prop valve, which has helped but not eliminated the proplem completely.
I read through topics on here and noticed a few recommendations about removing the stock prop valve? Will this sort the issue?
I have done the 15/16 MC, new lines all round, Skyline r33 brake booster.
Any help/advice would be appreciated.
Regards
