Installing BDS leaf Springs... got ???'s

Just recieved my 5" BDS Springs... Little bummed to find out they don't come with Bushings! That's going to set me back a couple days. My question is: They come with an 6* Shim installed. I'm moving from 4.5 RE springs and I previously re-did my spring perches to set my pinion angle. Is there some reason I will need to keep these shims on? Are they manufactured in a way that requires the shim?
 
You will have to install the leafs and remeasure your pinion angle to see if they are needed. But IMO 1/2" isn't a big deal.
 
Probably they assume you have a stock axle and figure that the 6 degree shims are going to get you close to where you need to be. If you have already rotated your spring perches on the axle for a 4.5" lift I would install without the new shims then see where you are, you are probably closer to right without them than with I am guessing.
