I know I'm not the only one whose boot has this warping on the spare tyre cover. This isn't my car, but you can see what I mean here.

I've always wondered why the cover that sits atop the spare tyre never fit properly. Now I know! Mine was crooked, and the wood/cardboard thing all bent and warped. I came across this picture today and it all made sense. There's supposed to be some foam that clears the spare tyre, with the cover then resting on this, and not directly on top of the tyre.

Now I probably doubt these exist anymore. I've never seen one in anyones Skyline, but then again I don't go pulling up the carpet on each one either lol. It looks like a 1inch thick kind of foam underlay, so I'm sure it's possible to cut one to shape and size. Though it would be nice to locate a genuine one.

Has anyone seen one of these in person before? Or even have one in their car?

I had that thought too Stephen. Do the compliance guys rip these out, or did they simply rot with age. Then it could have been the Japanese owners/sellers or the importers here tossing them. Will be interesting to see if anyone posts here who actually has one.

i through my wooden bit out as it was all kinds of f!#cked, but when i had it i noticed small bits of foam/fabric (similar color to that in the photo) on the bit of wood.

I don't have a space saver anymore just a factory wheel, so foam would make the carpet sit evenly instead of sagging down around the tire that is now sitting quite high, so if anyone did a diy foam insert post up the dimensions so we can all give it a go

The picture I posted Brock is from an R32 Vspec. So the dimensions for each car will probably be a little different. I have a R33 but the idea should be the same for each car.

I have those foam things stuck on the bottom of my wooden board too. Will take a picture of them tomorrow. It looks like the foam bits are the same thickness as the one in the picture.

So will try either Clark Rubber, Bunnings or a carpet place. It's pretty dense foam, so underlay might be too squishy for it. But still this should be a fairly simple thing to cut out once we find the correct foam to use.

A tip my neighbour told me to straighten the warped board was to soak it under a hose, then place cinder blocks or bricks on it. It should then dry straight. I'm not game enough to try that just yet, and was going to get some wood or plywood and cut a new one instead.

I've hated the sag in my boot. Feels like a sand dune sometimes. But the best part is I now know what is missing and it looks simple enough we can all make one.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
