Sorry I have been away from the computer also, my wife and I just had twin boys about 3 weeks ago!!! Anyways they guy never emailed me regarding the spring rate but I did talk to Pacific Customs, they recommneded on the front 150 over 200lbs and the rear 350 over 400.
Would you take some pics of your steering set-up? I am picking up a 091 tranny this weekend, I am hoping it holds up... I am actually located up in Washington but I am from California. I would love to come down and pound the desert. We are going to Dumont for Thanksgiving this year. I will send you an email right now. Talk to you soon!
Also I bet that things hauls with the turbo???? I heard around 400 horse?
