Thanks Jamie that's very useful advice. East Coast Z - I know very little about suspension setup so I'm just going to take it in at some point and have someone that does know have a look at it for me.
The best baseline setting is what is specified in the Nissan Factory Service Manual for your model year. Print out the specifications & take them with you. When you get there ask them what the alignment settings are for your vehicle BEFORE you let them do anything. Compare what they intend to set it to & what the Nissan specifications are. Make sure you get a printout of the final alignment settings front & rear. If the alignment can't be set within Nissan specifications, either the person doing the alignment has no idea, or there is something wrong with the vehicle eg, suspension or collision damage.
Dependant on modifications, its not always possible to set up the car to factory specs. A good example is with lowered z32's. when you lower the car with lowered springs or coilovers it effects the camber, and it cant be adjusted back to factory settings without using spacers or a adjustable camber arm setup. Flogged out bushings can also make getting a wheel alignment pointless as there is too much play in the suspension for the fine tuning done in a wheel alignment tio make much difference.
Obviously The solution to the lowering dilemma is to install adjustable components that will allow the suspension to be "tuned" to desired specifications. Wouldn't flogged out bushings be classified under 'vehicle damage'? Of course some people are only interested in the appearance of a lowered vehicle with wider than stock wheels. The detrimental aspects of incorrect wheel alignment doesn't enter the equation. These aspects include reduced traction, braking & tyre life.
