New wheels Need spring advice....
 

I have had my new fr500 wheels for about a month or so now. I see the big need for new springs!!! Now MT.com offers a few types eibach, Ford racing, etc. I have a 1997 V6 my wheels are 18x9 in the front and 18x10 in the rear. What springs should i go with to get the right stance without it being to low? Or should i go with a full kit from Eibach? If so sportline or pro kit or pro system plus? I already have some bump steer if i get a full kit will it eliminate the need for a bump steer kit?

I know lots of questions any thoughts?
