For 17" and smaller, replica wheels are probably fine. For 18"+, either get factory originals or name-brand aftermarket wheels like BBS, AC Schnitzer, etc. At least one 18" M-Parallel replica wheel owner now drives over railroad tracks at snail speeds because he bent three of them at 30mph.
Also, keep the tires inflated to the higher end of the range, like 38F & 41R. The ride harshness may be slightly increased but it will protect the rims better.
Cheers,
David - driving on 17 & 18" BMW factory wheels for almost nine years without any bends; can't say the same for various aftermarket wheels.
