pointless importing control arms .. just buy bushes from bmw, about 800 bucks .. the e39 540 and M5 are identical, then just have the bushes pressed into the control arms .. you only have to replace the control arms if the ball joints have play on them .. and if thats the case
buy them from imcomex in centurion, or buy from goldwagen .. same thing ..
if u order from overseas you gonna get the same thing .. Lemforder make the bushes for all the control arms except Meyle ones .. which are just as good quality .. however Meyle have HD bushes, heavy duty ..
if you want alternatively, you can order X5 bushes from BMW .. they are abit stiffer than normal bushes .. same price really
just buy the gibbo from BMW .. the M5's is abit thicker than 540 .. the 540's has gaps and places like goldwagen will sell u the 540 one
