i've had poly bushings in a street car and always have come away thinking i crossed the line away from good streetability. Too much noise, harshness and eventual squeeking. You can press new bushings into the arm.
For control arms, i used the e31 part, it's aluminum, like the the oe M5 plus it has a speherical bearing instead of a rubber bushing. For thrust arms, you can typically press in a new bushing into the old arm at least once. After that, the ball joint is probably getting to the point of wear such that it's best to just replace the entire arm.
As an aside on parts prices, if you have the part number (easily gotten off realoem.com) you can plug that into the parts seller i have listed in my sig. This is an internet arm of my local dealer and they're usually pretty good with pricing.
