well...
i droped the car to do my rear subframe and RTAB. so i asked charlie with which bushings i should go with and he suggest powerflex, but i cheaped out and told him to just install OEM.
i went to pick up the car and he tells me he installed powerflex for me with no extra charge!!
i mean what kinda business is that
Thank you charlie and abustaif...car drives like new now
A+ to charlie and bimmersport crew
