Hi Jason,
From your image, the front suspension arms are not correct in geometry.
I am not sure that your front ride height is actually at 4.5". But if it is, you have put the roll center at or below ground level.
This is very bad for many reasons, but namely because the car will try to jack the nose up in roll or bump.
The lower arms should be level or inner mounts slightly angled upwards to get the roll center above ground.
Exactly where the roll center should be in height is a sublect for a loooong thread, and it is not an easy thing to know. The main point is that it should never be at or below ground level.
I made a cheesy image from yours to point out the geometry, the yellow circle is the roll center. As further example, I include a diagram of the front Ferrari F50 suspension for comparison.
Hope it helps-
Cheers
Eric
