It's caused by having too much negative camber for the type of driving you do. If you drive in a straight line most of the time (ie, not on a track) then you cannot have much neg camber or you will wear the insides of the tyres. At the rear, the problem is made worse if you like to spin them up.

And yes, this is caused by being too low. As you lower Skyline rear suspension you automatically gain neg camber. You need adjustable polyurethane upper inner bushes at a minumum, or adjustable upper arms.

This has been discussed at great length, including recently, including the legalities of the various options. So have a look around.

Have this same problem, but didn't realise until recently.

I dont track or spin the rears, just normal daily street driving. My car is lowered and has -2 camber from what was on my receipt when i got my wheels aligned after the drop.

yes there are shops and i cant suggest any cos im in sydney but i just want to reiterate that if you want to stay lowered then you will have to use adjustable bushes to eliminate camber OTHERWISE if you purely want to adjust coilovers to eliminate camber you may be going back to stock height.

How much am i looking at for adjustable bushes, and do most mechanics/tyre places have them readily available?

Pretty much no mechanic or tyre place will have adfjustable bushes to suit any car (except maybe Commodores!) in stock. Pretty much any tyre place cannot be trusterd to spin spanners so discount them immediately. Pretty much any mechanic could order bushes in within a day. If you fit bushes you need a set for the upper inners and a set for the inside/front ends of the radius arms as well. This will cost you a couple of hundred.

The arms need to come off and a press used to get the old bushes out and new ones in most of the time. The labour will probably end up costing more than the bushes.

Adjustable arms that have rose joints on the end (like the GKTech ones) are not street legal. Adjustable arms with bushes (such as Hardrace ones) probably are.....but you might be in for an argument with a cop and then the pain of getting it defected and having to clear the defect anyway.

Rose joints. Heim joints. Ball joints. They're metal on metal. Really good location and articulation, but......extra NVH, they wear out because they get grit in them, they are an instant defect should a cop see them, and sometimes the cheap ones are shit quality and break.

Hard Race is a brand that does adjustable arms and the like but with hard rubber bushes in them instead of the rose joints used in most adjustable arms. There are one or two other brands out there that do the same. Bushes are squidgy material between two shells to allow arms etc to have some compliance instead of hard metal-metal contact.

    • Hi. This is just my curiosity because iam sure the tuner figure something out...but either way i want to ask. The "problem" is that the Nistune ECU (Stagea FW and RB25DET NEO from Stagea) sees many times the speed than the speedo does(he says the speedo show 120 km/h - correct speed and the ECU shows like 510km/h ) I told him that this car/tranny getting speed from rear diff. If iam not mistaken the RB25DET NEO "need" to see tranny speed sensor? (my tranny has the plug for it). So couple of "question" If he connects/wire the speed sensor to the tranny...are the signals gonna intervene and if...what if he disconnects the rear diff one and the speedo stops working? Or the "new" sensor from the tranny "take over" and will not going need the one from diff? As i said i know he figure/get that done...iam just curious to know what are the solutions 🙂 
    • Your IACV is set to idle too low. You need to adjust it via the screw Duncan mentioned. From memory it should be 650rpm with the valve electrics unplugged. What is it trying to idle at with the IACV plugged in?
    • Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
