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.

      Yeah you can. Cable tie the gauge to a windscreen wiper, or run it into the car and hold it with one hand, or have the neighbour's kid run alongside and tell you what it says.

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By GTSBoy · Posted

      I've never understood why this bothers people. Surely you'd be looking at a T3 flanged Garrett style thing, rather than a TD? You're unlikely to push a +T hard enough to need that much fuel. If you're not starting with most of the things you need to do that (ie, the bloody ECU!), you're better off just going Haltech/Link. You wil hate life a lot less. No. Just no. Just turbo it as is.

      Have you noticed if the squeak changes with temperature or after driving in the rain?

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.
