This is a can of worms. Read up on WRX forums and you'll find huge arguments about 5x100 bearings being junk, etc. But...I don't know if they used the same parts on the twins. And it's not spacers that cause wear, it's leverage. So a low-offset, narrow wheel will cause more stress on the bearing. A low-offset wider wheel would be better in this case. It's an involved subject, but honestly it's not likely to be a big deal for most folks. Hell, you'll probably be driving another car before it's an issue.
I'm pretty sure you can get bolt-on spacers as low as 10mm. They would have their own separate studs, but the downside is your wheels need to be able to accomodate the stock studs poking past the spacer.
I have 15mm bolt-on spacers on each corner, with shim spacers to clear the stock studs (didn't want to cut/grind them), for a total of 22mm and 23mm. The Discount Tire manager just about crapped himself and tried to tell me my wheels would fly off because of these. I beg to differ. I've checked the torque after putting some miles on and the lug nuts on the spacer had not budged at all. But just be aware that if you go to a big-brand tire shop, they may not even rotate your tires if you have spacers on.
