Last time I tested it, it made very little difference, but I still sit in the seat.

 

Rod, align it with both of you in it and see how the tire wear is.
Since Nick and a few others see a change then your tire wear is from toe out and you should notice a huge improvement over prior tire wear.

 

With 700f/650r, I measured a change of ~0.1 degree camber after when I had somebody sit in it. Negligible...

If you're worried about it, then set it up with a couple tenths less camber, then when you get in it'll be about perfect.

 

During my last alignment, we did a before/after comparison after placing 160 lbs of ballast in the driver's seat. We did not measure any deltas between the two. I'm running 18k front /16k rear spring rates.

 

What did you measure for toe?

 

Now those are some proper spring rates!

 

I always sit in the car, just so I can watch them if nothing else.

The car doesn't drive itself, you may as well be sitting in it for an alignment.

 

Thank's Mac,
We'll do that on the next alignment. We do go on the longest drives when both of us are in the car and that puts the weight up to 400+ lbs in the car. I posted this in the R/C forum because I knew that this is where I'd get the right answer to my question.

"I'm running 18k front /16k rear spring rates" Do you even need sway bars? LOL...

I always use ballast with performance alignments.

 

I remembering it making some difference in my 16k spring equipped S2000, but I'll check again when I do an alignment in a few weeks.
