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.

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.

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

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

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!

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
