2.5/1.5 sounds reasonable, might be a little more with the old spring sag but it will be close.
Thanks for the info, I ended up going with the 5100's set to 0 with toytec/eibach springs on the from and got 2.5inches of lift. I'm really happy with the ride and can't wait to do the back. For the back i'm thinking 5100's with toytec super flex coils.
