I am looking to upgrade the drum brakes on my 57 210. As far as i know everything is stock non power drum with the stock spindles. Looking at all of the kits there are way too many choices and i could really use some advice. It seems like you can spend a lot or a little depending on power upgrade / slotted vented rotors vs non / 1 piston caliper vs up to 6 / drop spindle vs stock. I am running what i was told are 15x6 rally rims from a 70s Camaro. they are a tight fit but don't rub as of now. I assume to keep them i would need to go with drop spindle kits to not move the wheels out or a zero offset kit. I am not against the drop as i do like the look of a lower front vs the rear and have been told the drop will help with handling. So i guess what I'm really asking is what do i NEED and what kits would you recommend. Not looking at a high performance race car type of set up and dont want to break the bank either but want safe and reliable. Thanks in advance for any advice.
