Hello everyone, I desperately need some help. Every year I need to go to the vehicle inspection office with my car. Everything is fine with the car except the geometry. They checked the alignment and they said I can't drive my car anymore. The only thing different with my alignment and the alignment of the vehicle inspection office is the rear camber. I'm running - 2 degrees camber on the back whilst they say I can only run - 1degree55 on the back. The alignment they use is from an Australian Nissan S15 spec-s but I drive a Japanase S15 spec-r. I've already went to the tire shop for my alignment and they can' t get my camber less than - 2degrees and also said a spec-s and spec-r has a bit of a different suspension so the alignment normally should be different. My car is bone stock for the moment and I can't figure out what to do now. I already searched the internet for days and the only workshop manual I find is the Australian S15 workshop manual but it doesn't say if it's for a spec-s or spec-r or autech version. Can someone help me to get the JDM factory alignment settings for the S15 spec-r? The vehicle inspection office wants to ban my car from the road now because they also don't have the official geometry of the s15 spec-r alignment.
This car is my dream car since I was a littke kid and I really really don't want to sell it. Btw I live in Belgium... If someone could help me, this would mean the world to me!!!

You can look up what the stock specifications are on alignment settings. Then take them to you alignment tech. He can put them into the alignment machine and then align your car. Should not be a real issue other then that car not being sold in your country therefore he wouldnt have it in his machine.

Here's what's in the factory service manual. I wonder if the issue is really as simple as what "format" you're using for camber measurement, decimal degrees vs degrees in minutes.
