Hi all.

need some help on brake kit fitment. The story is that I have a complete set of Wilwood kit W6A front, DynaPro back for 04 350z.

I want to fit them on my R34 GTR, but Wilwood in the US doesn't know enough about Skyline R34 GTR.

So to make this kit fit, mean either they find a GTR to try it or I send my car over, which is unlikly.

They've asked the follow questions, I wonder if any guru can help me out? I need info for both front and back. Many thanks. :D

Hub bore or hat center bore.

Bolt circle.

Stud diameter.

Caliper mount hole center to center.

Caliper mount hole diameter.

Caliper mount hole radius from center of hub.

Hub flange to caliper mount boss dimension (depth so to speak) Stock caliper piston(s) size.

MC bore.

Rear rotor dia.

Rear piston dia.

Hardline fluid line type. (M10 x 1.0 IF or Bubble for example) Required hose length speculating on caliper location.

      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?

      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/
