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

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
