New wilwood brakes on drawing board

[weq92f]

.

I purchased a set of Wilwood pro spindles for my C10 off a board member here a few weeks ago. Now I'm getting ready to pull the trigger on a big brake kit to go with the spindles ( MCBMatt has the best price I've found ). I've got a couple questions for you guys regarding this upgrade.

I'm currently running ECE 2.5" drop spindles + 2" drop springs. Front HD GM brakes 73-87 ball joints and tie rods.

new parts to go in:
831-14202: pro spindles for 71 thru 87 C10
140-15304: AER06: black 6 piston calipers, 14" rotors dr/sl
-- SS flexible lines
-- possibly new drop springs for heavier BBC

1) If you guys were picking caliper colors for a Hugger Orange truck what would you put on it: black or red with white letters.

2) In the installation notes for the spindles and brake kit I find this:
"THIS BRAKE KIT HAS A HUB OFFSET OF:
This Hub Offset will move the wheels inward or outward from the fender by this amount on each side of the vehicle"
This is concerning me a bit but I can't find any other reference to this "offset" anywhere else in the doco. Anybody know the offset for these? I'll put a call in to support Monday, but looking for answere from the board if it's available.

3) I'm running a BBC on SBC front springs I'm pretty sure as I cannot get all the bounce/float out of the ride with new shocks ( stock/standard shocks ). Would you all suggest my going to BBC rated drop springs ( if available ) or upgrading the shocks to more aggressive ones? I've read where somebody had the same problem on the board and went with BBC springs ( standard ) and cut off a coil or two. This leads me to believe BBC DROP springs aren't available.

4) are there any caveats to this type of upgrade I'm maybe not considering?

Thanks ladies and gents,
