Difference Between German And Japanese

[Tony-Bones]

Before any Geometry calibration is measured the car needs to be conditioned so that the chassis is in the correct position to overlap the target data (preloading). There are two main manufacturers, German and Japanese who's cars benefit by calibration regularly but they are miles apart in the conditioning requirements, these are.....

Japanese

For 90% of these cars all you need is the car :D

10% need a full fuel tank.

German

10% need a full fuel tank only

90% need....

1: 68kg on the drivers seat

2: 68kg on the passengers seat

3: 68kg in the middle of the rear seats

4: 21kg in the boot

5: oil level correct

6: coolant level correct

7: washer bottle level correct

8: transmission level correct

9: brake fluid level correct

10: all floor mats in situ

11: spare wheel and tools in situ

12: A "spreader rod" is needed to push the front wheels apart, loading the steering linkage

Oh and a full fuel tank.

The target calibration expects all the above conditions are observed if not then the adjusted calibration will be incorrect. Taking the fact that all Geometry positions are theoretical then the German parameters remove any real chance to analyse handling or tyre wear issues after the car is set.

No wonder the average German marque dealer charges £500 for calibration!
