Hey imo.If you replace all of the exhaust studs u r wasting your money.Do the ones that need to be done and leave it at that.

i had 2 replaced and the rest were left and nothing has gone wrong with the others.

You could also get a bloke to come out to u and do it on site but it may co$t a little more.

I probably will just get the broken one replaced, but I've had a lot of mixed opinions... most people have said I might aswell replace them all?

Was it the rear ones near the firewall?  These are the most prone to snapping.

Yeah it was. I have heard they are prone to breaking from old age and prolonged heat exposure.

Since its a pain in the arse to pull everything off -- particularly on GT-Rs -- I hardly see the point in saving $30. Do it once, do it right. The studs are subject to a lot of expansion and contraction, at differing rates, hence why they break. What happens if after torquing one up there is a hairline fracture and the studs breaks next day? Time to pull everything apart, new gaskets, blah blah blah.

im pretty sure you are right, the ones you need are around 50mm in lenght, 32mm wont be long enough.. :D

      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/
