wow.. sorry i guess i was misinformed when i picked it up then.. i dont really pay attention to the details when it comes to BMW stuff.. then yes its the oem stb..
im looking for a quick sale.. dont plan on picking up another z4 that this will fit on anytime soon. i have a 328 to hold me...
My lease just ended so im selling the OEM Strut Tower bar. This thing made a big difference in Canyons. I drive a lot smaller more nimble cars at the track and canyons, this definitely helped the car a bit.
the bar is pretty much flawless.. id say about 9.5/10. comes with 6 replacement wing...
