I wanted to replace my NON sport 528i suspension with the hr springs and sport bilsteins struts combo......... but i wanted to know if anyone has put the hr springs for the sport suspension on their NON sport 528i........ I figured the stock BMW sport suspension is about 1.5" lower than mine and the hr sport setup is about 1.5" lower than that so for me that would be an overall drop of 3" as opposed to the 1.5" drop hr has listed for there non sport package springs..... Any help would be appreciated thanks
