I talk'd to the guys who make this subframe, It's $1400 and requires modified spindles to eliminate bumpsteer

bumpsteer is when the toe changes in or out when the suspension is loaded or unloaded from the at rest position. Imagine attempting a pass while threshhold braking into a corner and your car darts one way or the other or side to side etc. Can get real scary. Can also get squirrelly while under hard accleleration or any bumps in the road, hence the term bumpsteer.

Typically the point at which the steering connects to the spindle is moved up or down depending if toe-in or toe-out is induced. This also looks to be the case with the 3rd gen spindles from the pictures.
