Rear suspension

[Loren]

I'm gonna bet the primary effect in play here is the "toe curve" of the rear suspension. It's designed to be slightly toed in at the factory ride height, and as the suspension compresses in a turn, it toes in a little more for stability. This effect is all built into the rear axle assembly and the angles at which it rotates. So, by changing to the upper holes on a lowered car, you're effectively putting things back into the alignment they were designed for.

To verify this, someone should carefully measure their rear toe before and after making this change. If I'm right, you should see less static toe out after than before.

Hmmm i just had a alignment done few weeks ago. When i get a chance ill do this and get a second alignment done and see the difference and post results for you guys Ill also take a few pics more pics if no one has done it by then to make a little more detailed DIY for those who dont know exactly what we are talking about yet. GOOD FIND!
