ok, just got off the phone with Ground Control. I told them that my car is a daily driver first, and it's an Autocrosser second, so I wanted a comfortable spring rate. I also told him about the Eibach sways that I want (more oversteer, along with adjustable endlinks; he already knew how the Eibach sways are

).
He recommended that I get 450F/400R. The regular off the shelf GCs for my car are 450F/300R. Anyways, if I were to go with a higher rate in the back than the front, along with the thick sways, it could be too much oversteer.
That being said, I asked him how the car would be performance and comfort wise on a scale of 1 to 10 (1 being the best comfort/worst performance, and 10 being the best performance/worst comfort)
He felt it would be a solid 6. That was cool, because I planned on asking this question, and stating that I would want a 6 (no BS).
Now that I've got that off my chest, I can go on and get as much seat time as possible
Also, I forgot to ask, but could I set the coilover to sit on the lower Koni perch, so I have to use less of the sleeve to lower the car? I would prefer to do that so I can decrease the chance of the spring rubbing on the sleeve...
