Just got my C5 ZO6 aligned for the coming autox and HPDE/PDX season.

Everything was way off and radically different from what I had installed last year at this time. I thought all it needed was minor tinkering, but I must admit the car feels much better after readjusting everything. Same experienced shop.

So I wanted to ask: how often do all of you completely redo your alignment? I get the impression that an alignment doesn't hold up that well to a season of autoxing and doing occasional track events (even with only 3K miles driving on the street).

Am I right about this?

I don't have an answer for you, as I just had mine done three weeks ago. However: It's my understanding that C5's and C6's that are frequently autocrossed have a tendency to trash front control arm bushings fairly regularly. Are yours stock/original?

I use the David Farmer method for checking alignment and adjust them myself in-season. Just need a straight edge, a measuring tape, and a level and you're set for checking your toe and camber.

I also mark the cam bolts and the tie rod ends after professionally setting all the alignments so I can periodically check for changes.

I agree with marking after a pro-job. Then you can see if things move. If you run sticky tires, like the gators, or think your vette's a rally car, you'll need to check more often!

here is another tip use a wrench on the cam bolts to hold them and then torque the nut to specs.
your alignment will last a lot longer

I do my own alignment and it's never far off if any. You have to make sure the shop torques the cam bolts at 125#. If they don't, it will move for sure.

I highly suggest marking your cam bolts, so you can verify nothing has moved. At this point, if your alignment changes, then your bushings are deforming.

And as ErnieN85 suggest, you absolution have to hold the bolt in place. If not, it will move when you torque the nut to 120ft-lb

Where do you guys get the paint pens for this stuff?

I used a long breaker bar on one end and torque wrench on the other. I did it in an oil chage pit. It has not changed in two years of track time & street driving.

Wal_Mart medium paint pen or a sharpie
