I think he is referring to a lack of self centreing steering.
Do you have a picture of the lower arms/steering track rods? What are you castor figures like?

micras run a panhard rod on the rear end, when you lower the car it pushes the rear axle to one side if i remember right it the to the drivers side so you have to shorten it I'm guessing you havent, that can make the car handle funny as its crabbing all the time, did you have it 4 wheel aligned as this would show if the rear axle is running parallel line to the front get the data you do have up asap

If the rear axle is out of line then most laser tracking kit will complain, as it uses the rear wheels as a reference to find where central is up front. If the rear axle's over to one side they'll be tracking it with a slight steering angle, and when you straiten it out it won't quite be right. It shouldn't make a huge difference in theory, but it will make a slight one. As said, getting it 4 wheel aligned rather than just the fronts should show this up. |

also on the rear pass side it shows a strange camber angle measurement of -0°57
opposite side is -0°25

Are you running cheap spacers? I had similarly strange alignment figures and I'm wondering if it's down to the cheap slip on spacers I've got, if their faces are not perfectly parallel it could show up as camber and/or toe.......

Geomtery looks fine (nothing majorly off), although you're running very little toe. This can reduce self centering and cause tramlining, although does make the car turn in well which is probably what you're reporting as 'handling nicely'.

Alignment looks fine to me. I'd want to match the front cambers so they're symmetrical but that's it. Rear camber is near enough, rear toe looks sweet so it's straight enough. Castor is fine too.
If the car is decked you could probably run zero front toe. I would.

thanks for the replies no spacers on these wheels ChrisT
i think the rear left is slightly bent or as it was sitting at the current time!
how could i get the toe higher? for a better pull in?
can i get away with unscrewing the tie rod ends a turn? but I'm thinking that will give too much!
i don't want to start rubbing the tyres!

looking at the print out from the alignment, i'd be trying to sort out the dodgy camber. positive on one side and negative the other will not help at all  |

Negative all round going on that sheet. I admit the passenger side shows to be exhibiting more camber.

As said, your front camber is a bit miss-matched, which wouldn't hurt to get sorted.
Even with a solid axle you should be able to adjust the rear camber by fitting shims behind the stub axles. (As long as they're a separate part on Micras anyway, which I'd expect them to be.) Although the rear camber's not actually out by much.

No way anybody would be able to notice 0.25 difference in rear camber  I guess it wouldn't hurt to fix the front camber though, but it's nothing that would give twitchy handling  how could I get the toe higher? for a better pull in? can I get away with unscrewing the tie rod ends a turn? but I'm thinking that will give too much! Me being the bodger i am i wouldn't hesitate a second to give it a go, start with half a turn. And you want more toe IN for stability, i.e screw the tie rod further in |

Ah, fair enough, you're stuck on that then. But as others have said, you won't notice the difference anyway even if you could change it that little bit. |
