Need help interpreting Camber/Height specs W202
 

My tires are wearing fine for now and I have no intention of fixing what "aint broke" but I thought I would have some fun and see if I could check my caster/camber myself, and this knowledge might come in handy some day. (Also keeps me off the streets...) Anyway, I bought a really neat gauge from www.racerpartswholesale.com that I heard about, and I got it and I am pretty impressed with the quality and accuracy for the money (39.99). Only problem is I can't figure out what the angle is supposed to be. I have alldata.com as I have previously mentioned, and the specs there appear to come directly from some Mercedes documentation. The main problem seems to be in measuring the height, since the specs do not appear to be an actual height measurement from ground to some point, but rather a reading on a mercedes measuring tool. For example, the rear height spec for the W202 sport model is -5mm and I don't think any of it travels below the road. Anyway, once you measure the height then you read the camber angle off of a chart. Does anyone know how to do a DIY height measurement for this car to get the camber angle? Or is there some other way to get the camber angle spec?

Thanks,

Mike
