Well, I've found them for $489 online, 17x9's and 17x11 set. 2 drag radials range from $160-$210 a piece, so figure $400, and then two front tires are about $100 a piece, so that's $200. Altogether, with rounding up, I figure $1100ish.
Whereas you're wheels are $750 + $85 per wheel for powdercoating (price YOU quoted at your work, probably a "hookup"), and the fact that your lips are chipped somewhat on the clear, and the tires are worn...and not the tires I want..that's $1100 for USED shit.
Make sense now?
