Why are you using SLR's specs ?

Regardless, all of you are going to have major problems soon with the amount of lift you've dialed in up front.

I've been running about 1.25" of clearance from the upper bump stop to the upper arm, and my steering crosslink is now toast, the end bushings are shot, and I have 3 degrees of toe-in play at the wheels.

A new one is going on next week, which should hold up for another 10,000 miles.
