been thinking lately about getting some racing seatbelts put into the car. since the bnrs come with the sockets to feed the belts through it be a great idea and looks great!

was wondering if anyone knew the legalities of them and if its hard to install them into the seats?

i do know with aftermarket seats and rails the belts bolt onto the rail and back seat bolts. wats the situation with standard bnr34 seats and rails?

thanks in advance

Two inch harness can be legal, providing the registration is changed to a 2 seater, and rear seatbelts are removed, however it must be engineered aswell.

3-inch harness can't due to the buckle design

Dont do it. You have to get the car engineered as a two seater, which means removing back seats, remving rear seat belts then going to Vic Roads and gettign your papers changed. This means from that day onwards you cannot legally carry passengers in the back seat or ever put the back seat back in.

If you want to get the papers changed back to saying its a 4 seater then you need to once again get the car engineered. This means not only the seat and belts come under scrutiny , but the whole car and any other mods you have.

They are also a pain in the ass to use on the street, they limit movement and you cant even change the radio station or air con settings when the harness is on Best bet is to keep your std seat belts and just use them. Using harnesses on the street is a bit silly, and if you must then use it in conjunctin with std seat belt as the places you have available to secure the harness means its more likely to injure you in an accident then help you.

SO, just be careful and do your homework thoroughly :rolleyes:

You can do it but there is only one type of harness thats legal it has the same type of buckle as a standerd car (push button) I would advise you to go to vicroads.com to check, and you can leave your back seats in so long as your harness does not interfere with the rear passenger (check this it's from memory) if you got though the rules and regs you'll find out we can get away with more than you think such as a roll cage doesnt need engineering for vicroads to pass it, just follow the guide lines they state and it all nice and legal but cams will need engineering just a couple of thoughts good luck

Well yes and no.

VicRoads requires and engineers depending on the situations

http://www.vicroads.vic.gov.au/NR/rdonlyre...265/0/VSI28.pdf

Reasons are - Modification to car structure, Seats/Seat Belts etc

Now, being a coupe, you wont get a full cage in there with the rear seats, therefore engineers is coming

true the seat belts are a grey area they say to use original points thats a bit hard as the seat belt clicky thing is part of the seat (R33 anyway) I spoke to them about that as im keen to put a cage in my car and what i was told it would br a quick check and thats about it i'm making my rail connect to the original seat fixing. With the rear seat your right if you put a full cage in it will need to be classed as a two seater as the bar work hinders the passenger from getting out quickly hopfully i'll be starting it soon i'll post up any problems i come aross in the fab section

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
