Ill try that Tuesday at uni I should be able to get on the four poster with the digital tracking! Ill report back!
As the rear spring hold the rear camera at max if I add an extra coil to the rear, this will make it stiffer with more preload! Right?

I'm not sure what you mean by 'the rear spring hold the rear camera at max'? Although unless changing to a completely different spring, I can't think of any situation where adding a coil will make the suspension stiffer. |

You can get it tracked all you like but that won't help you if it's a bump steer issue as tracking gauges are not designed detect that.

What I mean is that the rear springs push the damper upto max so it couldnt go higher. Hence adding a coil will make it stiffer through more preload!

I make Seth right on the wheel offset issue - if you look at early FWD cars on struts VS modern ones, negative scrub radius has been increasingly added to many designs over the years for a number of reasons - by running wheels that poke out more, you will be moving closer to zero scrub, the likely effects of that are:
More likely to torque steer or pull under braking
More likely to 'wander' around the straight ahead
Steering will probably feel lighter
If you are concerned with handling, it may be worth trying some standard offset wheels with similar tyres & pressures to see what, if any, the effects are.
I've mucked about with wheel offsets on RWD cars in testing for oval racing, the effects are noticeable.

why stiffen the rear? the rear wont have that much effect on the tramlining unless its stupid stiff/soft, or something is seriously out of alignment. which the readings you have posted seem to not suggest try and get the front set up so its either parallel or with toe in. i personally prefer slight toe out for better turn in, but then I'm also rwd  |

Ill set it so it has a total of 1 degree of front toe and set the camber
I want thy rear harder as I scrape with weight

Don't set toe to 1', it'll just muller the curse word out of your tyres and make the steering/tramling even worse. Leave it at stock or set it to zero. I can tell you now the problem isn't the alignment, though.
Without a closer look at the car I'd bet it's buggered tyres.

i can understand you saying the tyres, but its been the same through my minilites, on 155/70/13 and on my winter wheels 185/60/14 and with the standard steels today 155/70/13
ive matched the tyres as much as possible

I'm having problems with going straight, and as micras are very suseptable to road camber to start with, but I feel I'm always correcting something and rarely I can happily sit there with the steering wheel fully straight! Toe in will add straight line stability at the expense of turn in, toe out adds turn in ability but will make the car feel skittish. not hold a straight line. |

New or part worn tyres? Did they cover many miles before the suspension work? |

Don't set toe to 1', it'll just muller the curse word out of your tyres and make the steering/tramling even worse. Leave it at stock or set it to zero. I can tell you now the problem isn't the alignment, though. Without a closer look at the car I'd bet it's buggered tyres. A million times this. Secondly, the old rule of change one thing at a time applies. Change the toe, in measurable increments, or mark it so you can put it back to where it was if it's worse. Finally, it really does sound as if there's something worn out or loose in there somewhere. Check it all over, thoroughly just to be sure. Goodluck. |

What I mean is that the rear springs push the damper upto max so it couldnt go higher. Hence adding a coil will make it stiffer through more preload! Are you saying the dampers are at full extension when the car is sat on the ground? This. Is your rear suspension at full with weight on it? If not then adding more coils (if you're talking about an otherwise identical spring) will make the rear higher and softer. Pre-load won't increase your spring rate. If it is, it shouldn't be, a road car should not be running pre-load. The only real reason to use pre-load is to allow for ride height changes caused by downforce at running speeds, and I'm guessing that's not a huge issue with your micra . |
