im pretty sure its just a brace so it prevents flex within the unibody making the front stiffer and more responsive and for lowered cars im pretty sure it would be ok considering that pretty much any person that would want somthing like that is gunna have a lowered car now if u live in a place that has shity road /driveways/speedbumps then it will prolly rub on some shit depending on how low ur car is. id be buying this if my money wasnt tied into other parts already(N)
