You, your BMW and your alignment
It is critical to know that weights must be added to your vehicle for the accuracy of your alignment, (with the exception of some M3’s).
BMW alignment specs are accurate only in a loaded or active suspension condition. In other words “weighted”. An example would be: 150 lbs. both driver/passenger front compartment, 50 lbs. in rear compartment, 50 lbs. in the trunk, and a full tank of gas. Your suspension will then compress to a certain point and the specs become precise.
BMW has no alignment specs for an “unweighted vehicle”. Is your shop performing the correct alignment for your BMW? Yes, it does take more effort, and a little more time, but it will be correct and to BMW’s specifications. This is how we do it everyday and have been for, (what seems like), forever!
The downside, (if it is not done correctly), is uneven, accelerated tire wear, and higher fuel consumption. We all know that tires and fuel are both more expensive these days, so get it done right!
