Woops. Snapped the head off my disk guide screw

I don't know how it snapped off. I had the suspension out and when I went to put it back the disk was moving around. I found the screw and as I went to put it back in I noticed that it has snapped off in my hub.

Now, is that a problem? The wheel bolted back fine and I think the screw is just a helper so the disk doesn't fall off whenever the wheels come off. Am i right?

Thanks.

It does help centralise the disc as its a tapered head but it will be fine without it. If you can get it out and replace it you may as well but not the end of the world. Many cars don't have them at all.

These screws actually do a very bad job of locating the disc. They don't pull it anywhere near the centre.

If you're using oem discs that Centre properly on the hub then throw the screws away. If you have after market rotors that don't locate properly on the hub then use a dial gauge to correctly Centre the rotor and then use these screws to locate the rotors once it's in the right place. 

As an aside many race teams throw these screws away because they can cause problems.

The disks are after market but centre perfectly on the hub.

What guide screw?

These guys;

They screw the disk onto the hub so the disk doesn't spin when you put the wheels back on.

      Potential MAP Reference Point

      Isn't there a fitting on the back of the balance tube? That's what the OEM boost gauge uses.

      Potential MAP Reference Point

      By GTSBoy · Posted

      Getting a decent signal from all 6 throats is a challenge. I don't know for sure, but I suspect that the stock balance tube is not ideal for it. I have done it on an ALFA 4 cylinder (about 35 years ago, so don't ask for too many details). We drilled 4x holes in the manifold runners, put in some fittings and ran hoses to a decent sized (I think it was about 20mm diameter) pipe that ran the length of the inlet manifold. So, it was quite a decent volume. There is a "tuning" balance to be found between the volume of the common plenum on such a thing and the diameter of the pipes running from it to the runners. You need the volume to be large enough to damp out the sharp spikes in pressure signal you get as each runner gets sucked on by its cylinder, but not so large that it becomes too slow to respond to actual changes in MAP. And you need the hoses to be small enough to transmit the signal quickly, but not so small that they delay the signal. You might have to have more than one go at it, if there isn't any actual success based wisdom to be had here. Hopefully there is. Anyway, I would not do it on only a couple of cylinders. I would also not care about "permanently modifying a part". Just bloody drill holes and make stuff better. There is nothing sacred about any GTR unless it is a genuine museum piece that you shouldn't be modifying at all anyway.

      R34 GTT front hood lip

      By Kinkstaah · Posted

      The strange thing is this is a URAS front bumper (or clone of it). The bumper actually does not sit flush with the GTT hood - You need the addon to make the hood 'long' enough to reach the bumper. I have no idea why they didn't incorporate this piece into the bumper itself.. instead of sticking it to the hood instead.

      Another thought on this OLD topic: When you paint your bonnet lip, leave a small unpainted back lip/line along the back of the lip, where it rests on the bumper. That way, the line in the back is much more prominent than the gaps in the front/under the lip - and it breaks the hood-to-bumper connection at the "correct" place, when comparing to a GTR. I'm gonna do this with mine this week, so stay tuned for pics!
