May I ask why did you go iridiun and also why did you go 8's?

I was just wondering because from every thing ive seen you are better of running normal plugs and replacing then every 10k or so due to the fact they have a better burn under high load and it works out cheaper

I chose them because they quickly transport away the heat (they stay cooler) and that reduce the knocking (spontaneous explosions). I have run 6 and 7 graded plugs and going up to 7 made a good improvement. The more power the colder plug.

An ultra-fine (0.6mm) center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability.

They are not too expensive. So changing them every one or two years is OK with me.

The extreme top fuel machines go as high as 9-10 with lots of exotic material on the tips. That suit their engines quite well but for a modest +700 hp machine like mine, it is enough with grade 8 and the "standard" Iridium IX.

This is how to change the wheel studs to longer ones (not my car on some pictures)

Remove the wheels

Remove the bolts on the backside of the brake caliper (socket 17) and hang it up with a bit of wire.

Remove the center cover on the wheel hub with a flat screwdriver.

Remove the lock pin (replace with a new one)

Use a pair of flat pliers, squeeze the legs together and press out the pin

Remove the centre nut (socket 32). The wheel hub will start rotating, use a long bar or equal between the floor and the wheel studs to hold the wheel hub in place.

When the nut is removed, take out the washer placed behind it and pull off the wheel hub

Press the old studs out. If you dont have a wise or equal, you can hammer them out.

Please try to avoid using to much force when smacking them out, every blow will make small dimples inside the bearings. If you use a small sledge hammer One firm blow is better than multiple smaller ones. Support from behind is good to save the bearings.

Place the new longer studs in correct position (splines). Carefully knock them in a bit. Important that the splines are correctly alligned. Use a larger socket and a wheel nut and tighten till the stud is firmly seated towards the back of the hub..

Clean all surfaces and put new grease on the bearing surfaces. If you plan to use larger brake discs in the future, it is a good idea to remove the splash guard behinf the brake disc before you remount the disc.

Remount the washer, nut and locking pin. Assemble brake disc and spacer.

Remount the brake caliper

Mount the wheels and enjoy the wider stance :)

This is the result on my car (no spacers mounted yet and Camber not adjusted). This is also before the wider fenders are mounted.

I use a 5-stud wheel hub with pin studs. Make life much easier

I do not want to mess around with lots of hard to reach screws and nuts so I looked around to find a good solution.

Thanks to Creatix I managed to lay my hands on a bunch of really good Stainless Steel V-band clamps and flanges. They make life so much easier eliminating the hassle with aligning bolted flanges. Easy to mount and dismantle.

I will use them on the exhaust system, the down pipe, the front pipe, the two wastegates and on the turbon :P

    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
