I realize this is old but for future reference for other people who look..
You're running sway bars im assuming? If thats the case those pucks arent ever gonna come out no matter how hard you flex it, you dont have enough travel.
As for the tires you could make an add on craigslist saying that you will trade down to smaller tires of equal tread and quality and since they are giving the bigger and more expensive tire they can pay for your new mount and balance.
No new pucks, no new springs, no mo money spent!
