I know 7 people just in my area who have either Prokits or Sportlines who I talk to on a regular basis. I used to wonder which one I wanted to get, but they perform to what struts you're looking for. The sportlines were designed for a slight amount of stiffness over stock but mostly to eliminate all wheel gap. When I 1st called Eibach that is the information I got. The Prokits are what the name says.
"After the Sportlines sell enough it warrants the developement of a Kit of Professional springs for a little more performance, we call them the Prokit Series" they don't lower as much but are stiffer than the Sportlines. Anyway I've seen these in person as well as discussed them on DSM Tuning with Turbos and AWD owners, mostly of which live in my area. Most turbos in my area have either Prokits on KYB AGX or Illuminas. Some have the expensive Tein of HP complete coilover for raising and dropping for rallies or use Groung Controls with Illuminas or KYB. Anyway I Got the GC when the price was right. When I got my adapter for my front GC for use on umolested Tokicos they told me their springs were developed from the stiffer Prokit spings.

BTW Kory here are my spring rates for my Ground Control Slip Over Coil Overs: 450 in front and 250 in the rear. I called GC and asked them to give me a comparison between my GC CO spring rates and Eibach Prokit Springs -Get This- he told me they are about 3 times stiffer.
