Alignment question for the techies

I just got a $600 quote to install my suspension kit. (too high, I know)

The mechanic said it's a lot more than other places quote because the BMW needs to be "sandbagged" for the alignment. I'm sure he means weight needs to be added to certain points to acheive the correct results.

Is this true? Are shops who don't do this doing it wrong? I've had prev. alignments done for right around $60 on this car with no issues. My tires wear fine, steering is arrow straight, negative camber looks right for a BMW.

Just looking for someone to fill in the blanks. This guy is not doing the install but he got me curious about the alignment terms.

You need to have the correct weight in the car in order if you are trying to match the official BMW specs, which are given in that condition.

There's a thread or ten about that and other alignment questions, here's a couple to get you started.

Bear in mind you need the weights to do an alignment - you only need them to match the alignment readings as given by the BMW specs.

Just noticed I left an important word out of the prior post, corrected in bold above. Hopefully people were able to read between the lines, but my apologies for any confusion I may have sown.

You're certainly welcome. It was a bad alignment experience that first led me to this forum and I've since become a bit obsessive on the issue. But the nice doctor has a pill he says can help me...
