Here is the reply I got from them regarding the difference between kontrol pro and rally spec ar. Called him after as well and def reccomended the kontrol pro. He did also tell me the the chrome and orange version hasn't been made since 2008 so anything you buy new should be the black and orange ones.
Thanks for contacting us here at Ksport.
The Asphalt Rally setup has stiffer springs on it and the kontrol pro is actually the street setup. I would recommend the kontrol pro setup for the car as it is 36 way adjustable dampening and I used it on my street car for both auto x and nasa DE events up through time trials.
I can help you get a set on order for you car. The Asphalt Rally setup is more in the middle of the road in regards to spring stiffness.
The street kit is the kontrol pro, then the stiffer asphalt rally, then the RR version (road race) which I would not recommend be driven on a street.
Give me a call to discuss or order.
