Due to a brake upgrade the old spacesaver is now useless. Accordingly I've shoehorned an R34 GTR rim into the cavity normally occupied by the spacesaver, but now I need to secure it. I've got an idea to make up a new piece that goes through the bolt hole in the wheel and screws into the receiver on the bottom of the boot.

I've attached some images if I'm not making myself clear. I've also sketched up something I think I need to get made up to do the job. I'm wondering if I'm making life too hard. Is there another way? Has anyone else done this? Perhaps it's as easy as getting some off the shelf parts and putting it together myself? Keep it simple? Due to the 'cavity' in the rim where the wheel nuts normally go, I'll need a long Umbrako style head to be tightened with an allen key as there is not much room in there for a 'finger key'.

Probably the 2 biggest questions is the diameter of the rod and the pitch of the thread (which looks shallow).

Any advice gladly received.

Cheers.

bring the orininal one along to a specialty nut and bolt place to see if they have a bolt of similar diamitre/thread and length required of the same material. Should only cost you a couple bucks. Maybe saw the original thread off and weld the top of it to the new bolt so you can still and tighten it? You may even want to saw the head off the new bolt too for a flush weld.

This is the first thing that pops in my head.

For those who have a care factor greater than zero, the solution to this is go to a good bolt shop. Dandy Bolts gave me a bolt, washer, and allan key for $3.75 and my spare is now tied down nicely. Easy.

    • 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/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
