Aligning the suspension. How accurate?

[lal Naja]

I'm the final stages of setting up the suspension and I've set the car up on a perfectly level work surface. Frame has 5 1/2" ground clearance all around.

Wheel Camber on all four wheels is dead on.

Wheel Base measurement on the left is exactly the same as the right, exactly!. But the diagonal measurement for the four measuring points are off 1/4". So the four points make a parallelogram not a perfect rectangle. I Plan on finding out where the misalignment is and correcting it.

What have you guys found to be an acceptable tolerance?

This is my first Cobra build and I want it to ride and go where it's pointed. So all advice is respected and welcome.

Thanks,

Arthur

I just edited the above. I typed track Instead of whee base. Oops!
