C/C plates, bump steer choices

Hello, I will be installing springs into my Stang in the next couple of weeks. I am only lowering is ~1". My workplace (Hunter Engineering) wouldl like to do some testing on my car and offered to by C/C plates and bump steer (possibly) kits for my car. I was wondering what would be the best ones to get. I told them a price of the C/C plates would probably be around $150-$200. As for the bump steer kits, I didn't know what they were up to a couple of minutes ago, therefore I have no idea on price. Thank for your opinions and knowledge.

Are the partshopper on here well priced and good quality products
 
When you install the lowering springs, it changes the steering mechanism angles. The Steeda ball joints bring things back to the right angle, so there is no binding. My car drives much better since I installed the bumpsteer kit and ball joints. Just my $.02 worth.
