Hey Guys..

Had my skyline for a few weeks now, and im going through the receipts i have for it...

Came across this one from a tyre place...

I have 235/45/18X8's on the front, and 265/35/18X9's on the rear...

Does the skyline come with adjustable suspension, or for the above numbers would i have to have some aftermarket jobbies on the car ?? I took a look underneath, and cant see anything special..

Thanks in advance...

The rear end is adjustable for camber and toe. It would appear that the rear is stock, but has been adjusted for max (-ve) camber.

The front is only adjustable for toe. The numbers suggest a camber kit has been fitted.

The easy way to tell is the check all the bushes. From the factory, they are rubber; aftermarket is polyurethane in different colours (Whiteline's are usually yellow, others are dark blue, some others red).

Hi Gizmo, the only adjustment I can see that has been done is the removal of the exaggerated toe out on the left rear.

This is based on the columns being

Left, Initial Reading then Final (after adjustment) Reading

Right, Initial Reading then Final (after adjustment) Reading.

Can you please check this before you read any further.

If you confirm this, then the car has some problems.....

A caster kit needs to be fitted to the front, the left is 5 degrees and the right is 7 degrees. This can be corrected with the offset bush style of adjuster.

The front negative camber 1.3 & 1.4 negative is a bit more than I would run. Around 1 degree is my preference. This is again within the adjustment range of the upper control arm offset bush style of adjuster.

The rear is also a bit of a problem with 0.2 negative on the left and 2.0 on the right. This can be partially corrected by using the standard upper rear control arm adjuster. But I suspect you may have to resort to an aftermarket upper control arm offset bush style of adjuster.

Although the rear toe out on the left has been corrected, the overall rear toe at 0.8 out is not what I would recommend. I use around 1.0 t o1.5 of toe in on the rear. This helps reduce the tendency to oversteer on power application.

Hope that helps

Hey SydneyKid...

Just the response i was after...just to make sure i wasnt going boggy... :rofl:

As usual, you are correct on the headings and their meanings...

When i look at the front of the car, i could've sworn that the car looks uneven. I got a tape measure and measured from the bottom of the tyre to the top of the wheel guard (dodgy, i know). Its about 2mm difference consistently each side, and the tyres have same psi in each...

I have some cash put aside for mods, but now im wondering whether i should invest it in a whiteline handling kit to fix this....and if so, which one ??

OR - is there a cheaper option to fix this properly and get the same result - ie is the whiteline option overkill for my problem ??

Ive already planned the spending of my mods, and to go purchase this would wipe it all out !! :rofl:

Hi Gizmo, I would firstly get the alignment right with the necessary adjustable bushes. Then you can add the other Handling Kit bits as your budget permits. Give Whiteline a call on 02 9603 0111 and they will give you the prices of the relevant bushes.

Hope that helps some more

Damn...

Had a chat to Whiteline - very helpfull..

Looks like ill do it right first time, and spend the $$$ on the handling kit... :)

Means i may have to sacrifice other mods i had planned.. ;)

But - long term im sure ill be happier...

Anyone recommend an installer up the Central Coast for these kits ???

dude, first thing i'd do is drop the car into someone who knows Skyline suspension well and let them put it on a hoist. There maybe the possibility that the car has been in a kerb type incident previously or something has been bent some how. Fix the problem not the symptoms kinda thing ;)

  • 2 weeks later...

Hey Guys...

thought id finish the story...

got the whiteline handling kit installed, and found in the process that both front tyres were showing threads on the inside, due to not having a camber kit !!! :D

So - the handling kit and two front tyres later (235X40X18's thankyou very much !!) and the car sticks like glue to the road ...

Damn happy to go this option and leave it at that - with the current wheel/handling/suspension setup i dont plan on lowering the car, as it will cause more hassles daily driving in/out of driveways than be an effective mod...

and so - onward and upward to the drivetrain and engine mods...

thanks again to Sydneykid for the input...

Cheers,

Matt

Hey Matt, re the worn inside tyres, it was probably not caused by camber (unless they said that after checking the alignment specs). The worst wear on the inside of tyres comes from incorrect toe (either in or out). Very easy to fix with an alignment and can save a fortune on replacing otherwise good tyres

Hey Duncan...

True. I think it was a combination of factors, but overall it was mainly due to someone taking shortcuts (ie just wanting the 18inch fat tyres and not finishing the job)

Anyhoow - its all done now and so onwards and upwards to stage 2 !! ($$$ pending)

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
