Hello, I'm needing to replace the struts on my 1998 BMW E38 750il. I want to upgrade and came across this site offering air suspension for only $1,100 dollars. >> https://www.dhgate.com/store/product/the-new-bmw-e38-twisted-tooth-suspension/410432123.html << Does anyone have any experience with this brand or even hard of it?? If so let me know, this is quite interesting for the price and might be worth a look. Thanks...
