as in, to create some semblance of a straight chain line.
i've added spacers to the non-drive side of the rear wheel, throwing it off center by a few cm. is this going to cause significant handling problems or anything?

Yes. A few mm's will make a difference. I tried it once, and the bike was all squirrely like, and I couldn't ride no hands. Just redish the wheel, and all will be well.
Redishing just brings the wheel to center again, after you move the wheel over by spacers.

ok, thanks. i should add that it's a singlespeed freewheel, not fixed.

If its a screw on road hub and your using a freewheel I've had some success with old screw on clusters, stripping down the screwed cogset and spacing the desired gear to exactly where I want.
A good quality old six/seven speed will match a current BMX freewheel for weight and you have a choice of a single step range of gears.
Wait there's more you also get to use the lighter 3/32 chain and your road rings.
Haven't had any success with splined clusters though, concentricity seems non existence or a minor concern on the newer gear.

I've seen a wheel 6mm out of line work OK-ish. Touring tyres, and it was a bit rabbity - that seems about the max before it gets nasty.
