    I am running 9" of lift in back and a CV with 6 degree shims. My shaft and pinion angle are off about 4 degrees. Jesse from www.highangledriveline.com says if you are within 2 degrees on a CV shaft, that is about right. If I could get away with using 8 degree shims, I think I will go that route for the short term until I get time to remove and replace my 14 bolt spring perches.

    My local 4xshop sells up to 15 degree shims, with a 12 month driveline warranty. Any thing over 15 degrees they wont give the driveline warranty. Never had anything done by these guys but hear they are all right.
    Not saying that 15 degrees is ok, just saying that they do it.

    I think the shim issue out back is no big deal. it is best of you can use one shim though anmd not stack them IMO.

    Up front is a whole nother issue...
