8 lug brake upgrade options?

[FLYNAVY30]

Im looking at options to upgrade the brake system on my 8 lug C20. Ive seen all sorts of kits to upgrade the 5 lug, but is there anything for the 8 lug? Id like to get the biggest brakes I can fit under the 16 inch front wheels while converting the rears to discs. The factory brakes arent bad, but as a daily driver, Id like something that stops a bit better and has a better pedal feel. Right now, I really have to stand on the pedal to pull the thing down from speed, and it requires a full boot to keep it from creeping forward at a stop light.

Any input is much appreciated!
