Sportlines are 1.9" f/r i believe. prokits are 1.4" f/r.dho said:Boosterwitch said: "It will probably work. But, the sportline springs lower the car too much. The reason it's too much is because B13s and B14s have very little suspension travel. So when you lower them 2.25" you are almost on the bump stops. This usually kills struts pretty quickly. AGXs are much better, but with Sportlines you'll kill those fairly quick as well."
I thought the Eibach Sportlines were a 1.6" F/1.2" R drop? And, I currently have the sportlines with the GR2's on my car now. You can take a look at my car here: http://www.1minute.com/dan/dancar.jpg
