M35 Rear Suspension Troubles

[slippylotion]

Hi guys

I'm having a bit of trouble with the rear coilovers in my M35.

I have Tanabe sustec coilovers and can't seem to get the rear level. The rear passenger side always sits 7-8mm higher than the drivers side.

Here's what I have tried to fix it.

Both sides set the same height. = out of level

Drivers rear set higher = out of level

Swapped spring assembly side to side = out of level

Passenger set lower = out of level

Loosened all arm joints to rest bush tension =out of level

No matter what I do the passenger always sits 7-8mm higher and its p*ssing me off as I can't work out why.

So, anyone have any ideas what it could be and if you have had this problem or had to adjust one side different to the other to get them level?

And it's creaking badly on that side and again can't seem to stop it.

Thanks guys.

Don't worry - take it to Oval track and race.

Because NASCAR

I have nothing constructive to add. Sounds weird.

Interesting. If I set the spring at the same height on both sides the passenger side is about 8mm out. I dropped the passenger rear by 8mm and after letting it settle it's still about 3mm higher than the drivers side.

That said, I haven't loosened the arm bolts at all yet so maybe it has something to do with that.

So yours does the same!

At least I not going mad thinking its just my car. I've almost given up trying to sort it out.

I think the creaking noise I'm getting is from the rear swaybar D mounts. Will pull them out tomorrow and re grease them.

What heights did you run with?

Check which way the bolts are in. eg doing up one bolt on one side might make the suspension go up as doing it up on the other side might make the suspension go down. Or when you use your spanners you will notice pushing down one side and up on the other.

I have the same problem on my GTR even if I raise the lower side it just raises the other one aswell.

I havent got it sorted yet either. I put it down to a slight bent chassis from going up my steep drive way the same way every time. I need to come in the other way a few times to twist it back.

Just hit a pot hole or bump on the higher side it might raise the strut tower to the same height as both sides which will then lower your height.

Happy to say finally the car sits level and the creak has now gone. I adjusted the passenger side 10mm lower but it still sat higher. I also could not pin point that creak but my suspicions where toward the upper control arm and the sway bar.

So today when I got home I jacked her up yet again ? and it was creaking away if I lifted the hub assm up and down. I then disconnected the sway bar link to check it all out, all looked good so I put it back in. Then took it for a test drive and the creak had gone ? then when I got home the car was sitting level. I don't know how to explain it but both problems have now been sorted by removing that link and refitting it. Not sure if some how it was causing the problem 100% but it seems to have solved it and that's all I care about.

So now onto to fitting the trams shift kit this Friday/Saturday.

You fitting it yourself Paul?

[slippylotion]

Yeah doing it at a mates workshop. Spoke to Craig about it so all should be good. Just need to take our time and concentrate.

Yeah definitely none till all is good.

Nice one Paul. No workshop and a lack of confidence from me - I don't think I'll be tackling it myself any time soon. Are you getting it done Dunc?

I think I will eventually, I can get access to a hoist but I lack the confidence for this one so I'll be looking to get a workshop to do it

[slippylotion]

If all goes to plan I could give you guys a hand to fit it. Im very confident It will go smoothly.

Just waiting for my mate to confirm that I can use his hoist friday arvo / saturday.

[jasevr4]

Very interested to see how it all goes Paul. All the best with the job!

So what you're trying to say here... is you need Whiteline sway bars from Dale?

No issues with mine and I have the Whiteline front and rear sway bars, Whiteline rear links, and Dale's rear mounts. Works bloody awesome!

[slippylotion]

They would be nice but the only other plans I have for suspension is alignment bushes.
