Sit in Car during Alignment
I have a friend that does alignments and I bet him 20 bucks that sitting in the car during the alignment will change the alignment slightly.
He aligned my Vette without me in it, then again with me sitting in the DS.
It did change. Slightly, but it did change. I bought him a couple of 6 packs with his own money.
Fact is that I used to drive sprints and they really get out of alignment pretty quick and the suspension is such that a driver in the car changes it drastically.
The next time you have your Vett aligned ask the person doing the work to let you sit in the car especially if you track it.
There is a bit of a difference.

So what are you trying to say??
- I guess I could stand to lose 20 lbs lol.......Benpup - thanks for the advice -
I suppose this falls under corner-weighting and other such suspension fine-tune tweaks.
Most people would never notice or need it, but it is nice to know about if you do use the car to it's capabilities on a track.
best regards -

My guy lets me sit in the seat while he does the alignment.

During a flat out scale job, we use the rotor trick, or lead bags, or any to add up to the driver weight. Then once we are very close, we throw in a person, it does make a very little difference, but needs to be dealt with.

We have performed numerous custom alignments and corner balancing. Driver and any additional weight (Fuel, etc.) is crucial for precise measurements.
Both of these Vette's in the underneath are setup for road course. Driver weight and average fuel is taken into consideration.
The C5 sits on hyperco composite leaf springs, shocks, and t1 sway bars. The C6 sits on hyperco full coilovers and t1 sway bars also.
