Sand bags?

[SC986]

Sandbags? I know I'm kind of simple but couldn't one of them just sit in the car if they didn't have any?

I've certainly heard of the better, typically more track oriented shops wanting to simulate driver weight in the car, but as to why they would want your VIN I'm completely lost.

I believe they can tell the history of your car at the dealership. All mods and work done on the car is recorded. I imagine if your car has been highly modified it might affect their willingness to work on the car. Just a theory.

you gave the right response in saying goodbye.

I think if you would have asked for pre and post alignment numbers on a print out, the service manager's head would have exploded.

Whenever you have one of those types of conversations, jump into your car and immediately drive far away.

I went to a suspension tech session at one of the local Porsche shops a year or so ago, and one of the topics was corner-weighting.
The shop used big plastic bottles filled with water so simulate driver, passenger, etc. Then they went through changing this and adjusting that to get the corner weights right (or close). I suggested it might be easier just to move the bottles around in the car until the weights were right, but they didn't seem to want to do it that way.

My alignment guy will just let me sit in the driver's seat with a quarter tank of fuel while he does the alignment.

Yes, I know this is not how Porsche specs the alignment.

I also sat in the car when getting aligned so it is correct.

I wonder how you could balance the corner weight on a 986 since there are not any adjustments as there are in a 911.
