The 15mm spacer does not move the wheel far enough away from the hub to keep the OEM wheel studs from contacting the inside of the divots in the rim. 20mm spacers are thick enough to the point where the OEM studs do not really extend past the spacer and therefore have plenty of clearance with the wheel.

I would not have done it if I didn't get so much reassurance from the guys I knew were running 20mm bolt on spacers and running them hard.
