alignment question

Yes, according to the BMW alignment specs, the cars must be weighted down. Do they not have weights and sand bags for this purpose? If not, find a better shop. Is it perfectly OK to do without it, but you may not get the results you want.

For a street and/or track car that you drive by yourself all the time alone, you can simply align with driver weight in the seat and a full tank. For race cars, I align and corner balance with driver weight and at least 75% fuel load.

BMW no longer requires this if done at a BMW dealer since the alignment software automatically adjust the alignment settings based on measured ride height. Most shops thyat have newer racks and software will not require weighting either.
