Drag Racing Alignment?
I posted this in the Drag Racing forum, I hope to get more responses here.
I recently lowered my C5 so I'll need a alignment soon. Which specs would be the best for drag racing, stock, ZO6, or a custom one?
Btw, is it me, or the car feels like it hooks much harder now that it's lowered?
Thanks,

Re: Drag Racing Alignment? (Face)
I just had mine re-aligned, as I was looking for more straight line traction. We went slightly custom on the alignment, removing much of the rear camber. It now has -0.1 degrees camber on each rear side tire, so they stand up straighter and put more rubber on the road when accelerating. The stock and Z06 settings emphasize cornering, and set in more negative camber. :cheers:

Re: Drag Racing Alignment? (6Speeder)
Ahh: development:
To get an alignment suitable for the strip: take a set of wire ties and place them firmly around the shock rod. move them by hand so that as the shock moves vertically, the shock body moves the wire tie on the shock rod. Go to the strip and run a few times. measure where the ties are after each run. This is a measure of how much the rear of the car sags under powerful acceleration. Don;t be surprised when the left side does not squat as much as the right--this is torque stear from the motor.
Go to the alignment shop and add weight to the rear of the car until the rear squats the same amount as measured by the wire ties. Align the rear from this position. Do not align the front with the weight in the rear. Don't be surprised if the strip alignment is a pig on the street.
I'm going to stay out of the straight up versus standard camber debate.
You can also experiment with right rear toe. It should be very so slightly farther out than the left rear toe (but both must remain toed IN.) This can compensate for the torque stear of the motor under hard acceleration.

Ask Tom Hall. I know when they did his, he had them strap the rear down to simulate the suspension action when you hit it. Hopefully he'll see your post.
