Matt,
Thanks for the advice. I know work has 3 different type of disks. The A disk is like the normal disk and fits most front (bigger) calipers while the O disk has a mounting surface that has lesser clearance, just enough to accomodate smaller rear calipers while providing a wider lip. Lastly the R disk which are for the 4 pot (or more) calipers.
My front wheels are 15x7 et+25 A disk. Although i know this already, i still don't know if it will clear the willwood calipers.
